Several attempts were made to obtain the so-called "optic" rhythm from the eye-o

It is possible to consider calcium as of primary importance in initiating protoplasmic activity (compare Heilbrunn, '28, Heilbrunn and Daugherty, '33). The protoplasmic fluid when stimulated stiffens or clots and this clotting reaction depends in large measure on the presence of free calcium ions. B
## Abstract Amoeba responds to a mechanical shock by a cessation of movement which occurs shortly after the application of the stimulus. The length of the reaction time, the period intervening between application of stimulus and the response, varies inversely with the magnitude of the shock. After
