The discovery struck old Dr. Kent, Glora and Alan into a numb, blank confusion. The fly was scurrying along the floor close against the wall already it was as large as Alan's hand. Alan flung a bottle which was on the table beside him. It missed, crashed against the ceiling, came down with splintering glass and spilling liquid. Fumes spread chokingly over the room. The fumes of the shattered bottle of chemicals were choking Alan. He flung himself toward the monster fly, but Glora held him. He heard himself shouting. "Father, get back! It's too large! I've got to kill it!"
