## Abstract The rate of locomotion in Amoeba proteus is dependent upon the nature of the substratum, the nature of the different divalent and monovalent cations present, and the ratio of the amount of the monovalent cations to the amount of calcium or strontium. Calcium is more efficient than stron
## Abstract Isolated fragments produced by bisection of Amoeba proteus differ by their position in the original cell and by the presence or absence of the cell nucleus. Immediately after the operation, both types of anterior fragments preserve the former motory polarity, and do not interrupt locomo
