Abstract

The presence of microfibrillar structures in the nucleus and cytoplasm of Amoeba proteus has been described after glutaraldehyde and osmium fixation. The possible roles of cytoplasmic microfibrils in the contraction process of amoeba and nuclear microfibrils in the formation of the honeycomb nuclear lamina are discussed.

## 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
