At first, only very few corpuscles show knobs, and the knobs are extremely small and few in number, say only one, or at most two or three, on a corpuscle; but in the course of an hour or two, more cor- puscles protrude knobs, more knobs are pro- truded from one corpus- cle, and the knobs grow larger (Fig. 22, (i). Occa- sionally a knob is drawn in again, and the former contour reestablished.
