These latter unite again to form still larger masses, and ultimately, after several steps of this kind, only to be followed by prolonged observation, the different granule heaps collect into a single mass which, at first, is irregular and mamillated, but gradually becomes smooth and assumes an ovoid or spherical form. According to Nicolet, the contractile body-sub- stance of the animal diminishes and becomes more transparent in direct proportion to the increase in size of this central aggregation of granules. The move- ments of the Amoeba, also, become slower; it remains.
