gentlemen, you must understand, was only a fraction of the very first stage of growth. As you may have noticed, it was constantly accelerated. This acceleration attains a speed of possibly fifty thousand times that you observed. Beyond that, it is my theory, the change is at a uniform rate." He looked at the body of the fly, lying inert on the floor. "You can appreciate now, gentlemen, the importance of having this growth cease after death."

"Good Lord, I should say so!" murmured the Big Business Man, mopping his forehead. The Chemist took the lump of sugar and threw it into the open fire.
