Do you own an Android phone but feel restricted when compared to iOS devices? Have you ever wished there was a way to access specific apps without having to jump through hoops? Learning how to handle APK files will empower you and bring added flexibility to your Android device. Let us take a closer look at what APK files are and discover how managing them can change your mobile life forever. What Is An APK File? An APK (Android Package Kit) file functions similarly to an executable program (EXE) on Windows systems. It comprises all the elements needed to launch and execute an application on an Android platform. When you download an app via the Google Play Store, an APK file gets silently installed on your device. Yet, sometimes circumstances arise where we may prefer direct involvement with APK files. Why Should You Know About APK Files? Here are four convincing reasons why being familiar with APK files can elevate your Android experience: Early Access
Oftentimes, developers release newer versions of their apps before their appearance on the Google Play Store. Direct interaction with APK files allows you to indulge in fresh features ahead of everyone else.


Regional Restrictions
Residing in particular regions may prevent instant access to worldwide releases. Through manual manipulation of APK files, one can circumvent localized barriers effortlessly.


Version Selection
Perhaps you crave older iterations of an app no longer maintained by the creator. Or maybe you seek exclusive modifications that are only attainable outside conventional avenues. Either scenario becomes feasible once you grasp APK files.


Cost Considerations
Sometimes, price discrepancies exist across different markets for identical products. Acquiring an international version via APK files can result in cost savings. How To Deal With APK Files Let us now delve into straightforward procedures involved in safely and productively managing APK files. Downloaded APK Files Locating dependable repositories for acquiring APK files represents step zero. Regrettably, numerous online portals lack stringent verification processes. Renowned websites such as Apk.ortweb3.tools guarantee credibility and legitimacy. Refrain from visiting sketchy domains peddling dubious offers disguised as tempting lures. After identifying a legitimate website, browse the catalog employing any internet browser. Identify preferred programs, hit 'download', and preserve the APK file on your device. Installed APK Files Before continuing further, activate the 'Unknown Sources' setting nestled under Settings > Security. Note activating unknown sources entails embracing inherent dangers linked to external applications. Allow only established entities meeting high-quality assurance criteria. Having made adjustments, track down the stored APK file and tap it to commence installation. Adhere to subsequent directions, concluding successfully. Upon wrapping things up, remember to deactivate 'Unknown Sources.’ Managed APK Files Implement dedicated file supervisors to streamline organization tasks involving APK files. ES File Explorer, Total Commander, and Solid Explorer serve as exemplary specimens facilitating seamless browsing, classification, renaming, distribution, backup creation, and elimination of APK files. Moreover, contemplate utilizing cloud storage providers like Dropbox, Google Drive, or Box to safeguard crucial APK files. Merely transfer vital APK files to protected vaults, ensuring resilience against mishaps that result in unwanted deletions. Tips And Tricks Below are additional recommendations for enhancing proficiency levels regarding APK files: Verify Integrity
Before integrating APK files, scrutinize digital signatures confirming genuine origins and preventing tampering attempts. Most authenticated vendors exhibit transparency, ensuring enduring peace of mind during transactions.


Update Regularly
Periodically review archived APK files, updating obsolete entries and maintaining optimal functionality. Neglecting routine maintenance invites unnecessary complications, ultimately undermining efficiency goals.


Remain Vigilant
Never overlook potentially hazardous consequences lurking beneath attractive veneers, concealing latent threats lying dormant until activated unexpectedly. Practice discretion when venturing off beaten paths traversed less frequently. Conclusion Understanding APK files brings substantial command over your Android device, transforming it into a personalized tool that is tailored explicitly according to individual preferences.

Simple Steps To Handle APK Files Like A Pro

Lessons From a Six Month Job Search - AdatoSystems Now that I’m free to that I’ve landed at – a visionary company filled by an amazing group of folks who believe that the value of their team goes far beyond what they might offer to the business – I wanted to take a minute to reflect on my job search, comment on the state of the job market, and share some lessons I’ve picked up along the way. share the news Kentik Let me be clear – I’m under no illusion that the world has breathlessly awaited the thoughts of a middle-aged white dude and will now, graced with my heretofore-undiscovered wisdom, be a truly better place. People with far more knowledge, experience, and expertise have written and spoken on this topic, with data and examples that are far more eloquent and compelling than anything I could hope to share. No, my point in sharing this is to offer what little confirmation and comfort I can to anyone currently looking for work too. Confirmation that the job market is really, REALLY challenging right now. And comfort that the rejections and (possibly worse) the ghostings you’re getting daily are both common in this current trend, and also not at all a reflection on you, your skills, your experience, your value to a business, or your worth as a person. I’ll be blunt and honest: As a white (or at least white-passing), cis-gendered, heterosexual, middle-aged man with over 35 years of industry experience, I have literally every ounce of privilege a human body can contain – with the possible exception that I’m not the son of a CEO and will inherit the company someday. Despite all those advantages, it took me six months of solid searching to find my next gig. Even when you take into account that the job I was seeking (Developer Relations Advocate) is less common than, say, a staff developer or sales engineer, it’s still a significant span of time to find a job. Now, when I say it’s a “bad” job market, I want to offer some qualifiers only time and experience can bring: It’s not the 2009 “the housing market just crashed and we’re in the Great Recession” bad. It’s not the 2002 “the dot-com bubble just burst” bad, either. If we’re really trying to find the low water mark, it’s also not as bad as the 1973-1975 US recession, let alone the Great Depression. But playing the “back in my day” game is cold comfort to anyone looking for a new job in the here and now, whether by choice or due to one of the far-too-common layoffs playing havoc with the tech industry right now. At the same time, the context offers some reassurances: Yes, it’s bad. No, it’s not the worst ever seen. And in those other cases, the economy and job market bounced back. While financial analysts will tell you it took 15 years for the NASDAQ to recover from the 2000 dot com bubble, most folks in tech will say that the job market cleared up in about 8 to 18 months, depending on where you lived and what you did. The market recovered from the 2009 housing market crash that triggered the Great Recession in about 4 years. Employers began adding jobs a year after that. Beyond context and perspective, there are other lessons I’ve learned, which I plan to share in upcoming blog posts. But my message for this one is pretty simple: Being honest with yourself will carry you forward when everything else seems uncertain. Take time every day (yes, every day) to check in with yourself and ask if the goals you are pursuing are the ones you still want, and whether the cost – in time, energy (physical, mental, emotional), and also money – are still worth it. If the equation doesn’t balance out, be equally honest about what you think would. I have a few friends who have done this math and pivoted to entirely different careers, or to different areas of tech, or who have put their job hunt on hold. All of these are valid choices and don’t let anyone tell you otherwise. At the same time, the job market won’t be this hard forever. By all indications, it’s not even “this hard” by the time you read this post. Things appear to be easing up a bit. While that might be the result of a , it could just as easily be a sign that things are looking up. Only time will tell. September surge From the start of my job search, I had an inkling that my experiences might be the source of a blog. Actually, who am I kidding? I *KNEW* that I’d try to turn this into a blog, no matter what happened. In any case, I resolved to keep copious notes on which companies I applied to, and how those conversations went. What I hadn’t expected was how hard it would be to turn those notes into a meaningful visualization. As it turns out, I needed three separate graphs to really convey everything about the process. This first animation (courtesy of ) does a good job of showing the number of simultaneous job conversations over time. Flourish HackerNoon doesn’t allow embeds from Flourish, so you’ll have to follow the link here: https://public.flourish.studio/visualisation/14974769/ But it fails to really give you a sense of how those conversations went. For that, my good friend and former colleague suggested I use a Sankey view. Honestly, I struggled to figure out exactly HOW to turn my information into Sankey data, until I saw from . Thomas LaRock this post Eric Browning But even those two graphs still fail to convey the sheer volume of applications, rejections, and so on. For that, I’ve defaulted to a simple bar chart: Across six months, I applied to over 40 companies, actively interviewed at 30, and gained a lot of interesting insights along the way. I plan to share some of those lessons in the coming weeks, and even the output from some of the take-home assignments I was given as part of the interview process. But for now, my main point is: You can do this. You can handle it. It’s a lot, but it’s not more than you can bear. You may need to approach it differently or consider an alternate path forward, but it’s never the less, something you can do. If you’d like to share your own experiences in the comments, I’m sure other folks who are in the midst of their own job search would find it helpful too. Also published here

Scientific American, Volume XXXVI., No. 8, February 24, 1877 by Various, is part of the HackerNoon Books Series. You can jump to any chapter in this book . The Speaking Telegraph. here The Speaking Telegraph. We have heretofore given accounts of the wonderful success of Professor Bell in transmitting the vibrations of the human voice by electrical means over a telegraph wire. He has lately made improvements in his method of transmission, by which he dispenses with the use of the battery, and substitutes the magneto-electric plan of producing the current. The Boston describes a recent experiment with the new apparatus, by which conversation and singing was successfully carried on between Boston and Malden, a distance of six miles. The telephone, in its present form, consists of a powerful compound permanent magnet, to the poles of which are attached ordinary telegraph coils of insulated wire. In front of the poles, surrounded by these coils of wire, is placed a diaphragm of iron. A mouthpiece to converge the sound upon this diaphragm substantially completes the arrangement. As is well known, the motion of steel or iron in front of the poles of a magnet creates a current of electricity in coils surrounding the poles of the magnet, and the duration of this current of electricity coincides with the duration of the motion of the steel or iron moved or vibrated in the proximity of the magnet. When the human voice causes the diaphragm to vibrate, electrical undulations are induced in the coils environing the magnets, precisely analogous to the undulations of the air produced by that voice. These coils are connected with the line wire, which may be of any length, provided the insulation be good. The undulations which are induced in these coils travel through the line wire, and, passing through the coils of an instrument of precisely similar construction at the distant station, are again resolved into air undulations by the diaphragm of this instrument. Transcript The experiments were as follows: Telephones having been connected with the private telegraphic line of the Boston Rubber Shoe Company, conversation was at once commenced. Stationed at the Boston end of the wire, Professor Bell requested Mr. Watson, who was at the Malden end, to speak in loud tones, with a view of enabling the entire company at once to distinguish the sounds. This was so successful that a smile of mingled pleasure and surprise played on the features of those present. That it, however, might not be supposed that loud speaking was essential to intelligibility, Mr. Bell explained that soft tones could be heard across the wires even more distinctly than loud utterances, even a whisper being audible. In confirmation of this statement, Mr. Watson commenced speaking in turn with each member of the company; and after the efficiency of this method had been proved to the satisfaction of all, he took up a newspaper and informed the assemblage that gold had closed the previous evening at New York at 105-5/8. As there were quite a number of business men present, the effect that this practical demonstration of the value of the telephone produced can scarcely be exaggerated. Other passages from the daily journals were then given, and by this time the desire for conversation having become general, Mr. Watson was plied with questions such as: "Is it thawing or freezing at Malden? Who will be the next President?" etc. It was remarkable that Mr. Watson was able to distinguish between the voices at the Boston end, he calling at least one gentleman by name as soon as the latter commenced speaking. This went on for some time, until a lady at the Malden end sent the company an invitation to lunch per telephone, and an appropriate response was made by the same medium. At length the Boston company were requested to remain quiet while a lady at the other end conveyed to them the sweet strains of music. The assemblage thereupon listened with rapt attention while a young lady commenced singing "The Last Rose of Summer." The effect was simply charming. The sound of the voice penetrated into the Boston end of the telephone with distinctness equal to that attainable in the more distant parts of a large concert room, and a unanimous vote of thanks was sent by the handy little instrument which had procured for the assemblage so agreeable an hour.

Scientific American, Vol. XXXIX. No. 6. [New Series.], August 10, 1878, by Various, is part of the HackerNoon Books Series. You can jump to any chapter in this book . A VELOCIPEDE FEAT EXTRAORDINARY. here A VELOCIPEDE FEAT EXTRAORDINARY. Two intrepid velocipedists, M. le Baron Emanuel de Graffenried de Burgenstein, aged twenty years and six months, and a member of the Society of Velocipede Sport, of Paris, has accomplished, with M. A. Laumaillé d'Angers, the greatest distance that has been made with a velocipede in France. Leaving Paris on March 16, they returned on the 24th of April, after having traveled a distance of more than three thousand miles. Their route extended through a part of the west, the middle, and the south of France, Italy, and southern Switzerland. They traveled through Orléans, Tours, Poitiers, Angoulême, Bordeaux, Montauban, Toulouse, Montpellier, Marseilles, Toulon, Nice, Menton, San-Remo, Genoa, Turin, Milan, the Simplon—where they barely escaped destruction by an avalanche—Vevay, Berne, Lausanne, Geneva, Dijon, Troy, and Provins. The longest distance that they accomplished in a single day, was between Turin and Milan, a distance of 90 miles, which they made in 9-1/2 hours. Superior Excellence of American Goods. The , of Birmingham, England, remarks with regard to American competition, that "perhaps the most humiliating feature of the business for British manufacturers is the fact that their competitors are prevailing, not through the cheapness, but through the excellence of their goods. Time was when English workmanship ranked second to none, and the names of our great manufacturing firms were a guarantee for the sterling quality of the goods they turned out; but competitions, trades unions, piece work, short hours, and other incidents of the 'march of progress' have altered all that. Complaints, received by hardware merchants from their customers abroad, are not confined to the goods of second class firms. Manufacturers who have obtained a world-wide reputation for their products are frequently convicted of sending out scamped and unfinished work, and they do not venture to deny the impeachment, pleading only that the most vigilant must be sometimes at fault, and that their men, unfortunately, are not to be depended upon. In other cases it is the merchants or their customers who are to blame for the inferior quality of the articles by cutting prices so low as to preclude the possibility of honest work, thinking, probably, that anything is good enough for a foreign or colonial market. But whatever the cause, the fact is now undeniable, that a great deal of the manufactured produce shipped from this country of late years has been of a very low standard, and that the American manufacturers have consequently had an easy task in beating it." Post Petroleum Oils as Lubricators. Oils from petroleum are now produced suitable for nearly every mechanical process for which animal oils have heretofore been used, not excepting those intended for cylinder purposes. A serious objection attaching to the animal oils is present in petroleum. If, through the exhaust steam, some of the oil be carried into the boiler, foaming or priming is the consequence, but the same thing happening in the case of petroleum is rather a benefit than otherwise, for it not only does not cause foaming, but it prevents incrustation or adhesion of the scale or deposit, and this aids in the preservation of the boiler, and is perhaps the best preventive of the many everywhere suggested. Often, in removing the cylinder head and the plate covering the valves of an engine, we see evidences of corrosion or action on the surfaces, differing entirely from ordinary wear, and the engineer is generally at a loss how to account for it. According to the general impression grease or animal oil is the preservative of the metal, and is the last thing suspected of being the cause of its general disintegration. The reason of this is that vegetable and animal oils consist of fatty acids, such as stearic, magaric, oleic, etc. They are combined with glycerin as a base, and, under ordinary conditions, are neutrals to metals generally, and on being applied they keep them from rusting by shielding them from the action of air and moisture. But in the course of time the influence of the air causes decomposition and oxidation, the oils become rancid, as it is called, which is acid, and they act on the metals. What happens at the ordinary temperature slowly goes on rapidly in the steam cylinder, where a new condition is reached. The oils are subjected to the heat of high pressure steam, which dissociates or frees these acids from their base, and in this condition they attack the metal and hence destroy it. This applies as well to vegetable as to oils of animal origin, fish or sperm oil included. Petroleum and oils derived therefrom (generally called mineral oils) are entirely free from this objection. Petroleum contains no oxygen, and hence it cannot form an acid, and therefore cannot attack metal. It is entirely neutral, and so bland that it may be and is used medicinally as a dressing to wounds and badly abraded surfaces where cerates of ordinary dressing would give pain.— Coal Trade Journal. Influence of Light on Plants and Animals. Professor Paul Bert, who has recently devoted a great deal of attention to the study of the influence of light on animals and plants, denies that the leaves of the sensitive plant close on the approach of evening, the same as if they had been touched by the hand. On the contrary, he finds that from 9 in the evening, after drooping, they expand again and attain the maximum of rigidity at 2 in the morning. What is commonly called the "sensitiveness" of plants is but the external manifestations of the influences of light. Professor Bert placed plants in lanterns of different colored glass; those under the influence of green glass drooped in the course of a few days as completely as if placed in utter darkness, proving that green rays are useless, and equal to none at all. In a few weeks all plants without exception thus treated died. It has been proved by the experiments of Zimiriareff that the reducing power of the green matter of plants is proportionate to the quantity of red rays absorbed, and Bert shows that green glass precisely intercepts these colored rays, and that plants exist more or less healthily in blue and violet rays. In the animal world phenomena of a directly opposite nature are found, and of a more complex character. Here the light acts on the skin and the movements of the body, either directly or through the visual organs. M. Pouchet has shown the changes in color that certain animals undergo, according to the medium in which they live. For instance, young turbots resting on white sand assume an ashy tint, but when resting on a black bottom become brown; when deprived of its eyes the fish exhibits no change of color in its skin; the phenomenon, therefore, seems to be nervous or optical. Professor Bert placed a piece of paper with a cut design on the back of a sleeping chameleon; on bringing a lamp near the animal the skin gradually became brown, and on removing the paper a well defined image of the pattern appeared. In this case the light acted directly, and without nervous intervention. If, however, the eye of the chameleon be extracted, the corresponding side of the animal becomes insensible to the influence of the light. Professor Bert's conclusion, therefore, is that the circulation in the transparent layers of the skin must be affected by light. According to Dr. Bouchard a sunstroke is the effect of the direct action of light upon the skin, produced by the blue and violet rays. The heat producing rays have no part in such accidents, as proved by the fact that workmen exposed to intense heats do not feel their fatal effect. Professor Bert, in a series of experiments on a variety of animals, found that none avoided light, but all rather sought it; and the lowest forms, like the highest, absorbed the same rays. As regards intensity of color, however, there was a difference, some being more partial to one ray than another. Thus the microscopic daphne of the pond preferred yellow; violet was less in request; spiders seemed to enjoy blue rather than red rays—so resembling people suffering from color blindness. No two persons are sensible to the same shades or tones, while absorbing the same light; and this would seem to indicate that the retina possesses a selective power. New Mechanical Inventions. An improved Weighing Scale has been patented by Hosea Willard, of Vergennes, Vt. The object of this invention is to economize time in ascertaining the weight of an article by avoiding the necessity for shifting the poise on the scale beam. It consists in providing a scale beam with a number of dishes suspended from different points on said beam, and representing or corresponding with different weights, so that the weight of an article may be ascertained by placing it in one or more of said dishes and observing which dish is depressed. William John, of Rigdon, Ind., has patented an improved Tire Setting and Cooling Apparatus, by which the tire may be set by one person, easily and quickly, without burning the fellies, and without straining the wheel by the unequal cooling of the tire. Joseph A. Mumford, of Avondale, Nova Scotia, Canada, has patented an improved machine for Sawing and Jointing Shingles. This machine cannot be properly described without engravings. It has an ingenious feeding device, and its flywheel carries the jointing knives. Ill-balanced Production. The Philadelphia sensibly remarks that the popular complaint of over-production is a mistake. Though of a few things we make or mine too much, our main trouble arises from not producing enough, in variety if not in quantity. Record "The wants of mankind never can be satisfied. Every new means of supplying a want creates new wants. They grow by what they feed on. As long as humanity is so constituted, over-production, in a general and enlarged sense, is impossible. It is this impossible thing with which the reformers would deal who propose to work fewer hours each day, or fewer hours in the week. The trouble they deplore does not exist; the remedy they propose defeats itself. A man cannot get rid of his load by shifting it from his right hand to his left hand. Production will not be stopped by making men their own employers certain hours in the day or certain days in the week, instead of allowing them to pursue their usual avocations. "The real trouble, which the labor reformers seem incompetent to fathom, is that there is not enough diversity in employments. What is desired is more work in productive enterprises, a more diffused industry, and a closer commercial connection with those countries wherein we can make desirable exchanges both of our raw material and our manufactured products. Every miner that drops his pick and takes up a hoe, every idle man that turns himself into an earner of wages, every person that picks up some loose thread of employment, every capitalist that takes advantage of stagnating industry and cheap material to build a house or beautify or improve a country seat, or set on foot some new process of manufacture, does something toward working out the problem which is puzzling the economists. In good time the surplus iron and coal will be sold; new populations will want new railroads; recuperated capital will gather confidence and take hold of new enterprises, and the whole nation will move forward again to more assured prosperity and to vaster undertakings." Labor in Germany. The consul at Barmen reports that for agricultural labor the pay varies greatly, according to the proximity to or remoteness from manufacturing centers; and ranges from fifty-six cents a day in the neighborhood of Barmen to thirty-one cents a day in the lower Rhine valley, and as low as eighteen cents in parts of Silesia. At Barmen, Crefeld and Düsseldorf, carpenters, coppersmiths, plumbers, machinists and wagonsmiths earn fifty-one to seventy-five cents daily; saddlers and shoemakers forty-seven to fifty-two cents daily; bakers and brewers, with board and lodging, from $1.42 to $2.14 weekly, and without board from sixty cents a day to $4.28 a week; farm hands are paid from $107 to $215 yearly, with maintenance; railroad laborers from fifty-six to eighty-[Pg 90]three cents per day, and as high as ninety-five cents daily for piece work on tunnels; silk weavers can earn $2.15 to $2.85 a week per loom; factory women $2.15, and children $1 a week. Business and wages are very low. In good times wages are eighty per cent higher. The cost of the necessaries of life has increased some fifty per cent in thirteen years, although it is now but little higher than five years ago. A man and wife with two or three children can live in two or three rooms in a poor and comfortless manner for $275 a year, and to support such an establishment all the members have to work ten or twelve hours daily. For a family of six persons the cost is about $7 per week—an amount but few families can earn, as the depression of trade and the reduction of time allow few to do a full week's work, although wages are nominally a trifle higher than five years ago. Petroleum June Review. DRILLING WELL ACCOUNT. The low price of oil and large accumulation of stock in the producing regions have had the effect to lessen operations in this department during the month of June. The total number of drilling wells in all the districts, at the close of the month, was 266, which was 110 less than in the preceding month. Rigs erected and being erected 243, against 309 last month. The number of drilling wells completed during the month was 269, being 151 less than in May. Aggregate production of the new wells was 3,788 barrels, against 6,851 barrels in May. The total number of dry holes developed in the month was 22, against 42 in May. The operators in the great northern field (Bradford district) have curtailed operations to an extent which will compare favorably with the operators in the other portions of the producing regions, as will be seen by the following statement, namely: Number of wells drilling at the close of the month, 187, against 284 at the close of the previous month. Number of drilling wells completed in June, 193, against 346 in May. Number of rigs erected and being erected, 196, against 234 in May. PRODUCTION. The daily average production for the month was 40,575 barrels, being a decrease of 227 barrels. The new wells completed in June failed to make good the falling off of the old ones, by decreasing the daily average 227 barrels. Bradford district shows a daily average production of 16,000 barrels, being an increase of 1,280 barrels over last month. The aggregate production in June of all the other districts combined, with the aid of 76 new wells, decreased the daily average 1,507 barrels. SHIPMENTS. The shipments in June, out of the producing regions, were 174,225 barrels larger than in the preceding month. The total shipments of crude, and refined reduced to crude equivalent, by railroad, river and pipes to the following points, were 1,135,119 barrels: New York took 555,794 bbls. Pittsburg " 153,182 " Cleveland " 239,389 " Philadelphia " 73,426 " Boston " 29,266 " Baltimore " 26,623 " Richmond " 7,000 " Ohio River refiners took 5,200 " Other local points took 45,239 " Total shipments 1,135,119 " Included in the above shipments there were 140,299 barrels of refined from Titusville and Oil City, which is equal to 187,065 barrels of crude.— Stowell's Petroleum Reporter. Remarkable Poisoning of a Lake. A contributor to describes the remarkable poisoning of Lake Alexandrina—one of the bodies of water which form the estuary of the Murray river, Australia. This year the water of the river has been unusually warm and low, and the inflow to the lakes very slight. The consequence has been an excessive growth of a conferva which is indigenous to these lakes and confined to them. This alga, , is very light and floats on the water, except during breezes, when it becomes diffused, and being driven to the lee shores, forms a thick scum like green oil paint. Nature Nodularia spumigera This scum, which is from two to six inches thick, and of a pasty consistency, being swallowed by cattle when drinking, acts poisonously and rapidly causes death. The symptoms of the poisoning are stupor and unconsciousness, falling and remaining quiet (as if asleep), unless touched, when convulsions are induced, the head and neck being drawn back by a rigid spasm, subsiding before death. The poison causes the death of sheep in from one to six or eight hours; of horses, in from eight to twenty-four hours; of dogs, in from four to five hours; and of pigs in three or four hours. A shows the plant is rapidly absorbed into the circulation, where it must act as a ferment, and causes disorganization. As the cattle will not touch the puddle where the plant scum has collected and become putrid, all they take is quite fresh, and the poisoning is therefore not due to drinking a putrescent fluid full of bacteria, as was suggested. post mortem When the scum collects and dries on the banks it forms a green crust. When, however, it is left in wet pools it rapidly decomposes, emitting a most horrible stench, like putrid urine; but previous to reaching this stage it gives out a smell like that of very rancid butter. A blue pigment exudes from this decomposing matter, having some remarkable properties. It is remarkably fluorescent, being red by reflected and blue by transmitted light; it appears to be a product of the decomposition, and allied to the coloring matter found in some lichens.
