THE EGG (Continued)
Too Long; Didn't Read
“Let us return to the hen. We know the calcareous nature of the shell; now let us look at the structure. Open your eyes wide and look attentively; you will see on the shell, chiefly at the large end, a multitude of tiny dents such as might be made by the point of a fine needle. Each of these dents corresponds to an invisible hole that pierces the shell through and through and establishes communication between the interior and the exterior. These holes, much too small to let out the liquid contents of the egg, nevertheless suffice both for the emission of humid vapors, which are dissipated outside the shell, and for the admission of air, which penetrates within and replaces the evaporated humidity.
