REFERENCE HANDBOOK OF THE MEDICAL SCIENCES Cell Vital Phoperties of Cells.—Under this licadingare groiipeti the plioiiomena of movemenl, irrilabilily,metabolism, iiiid n prodiictioii. Cells exhiint the [jhenoinena of movement underthree forms: proloplaamic, ameboid, and ciliary. Proloplnsmir movemenl is ditlicult of observationon account of the slowness of the process. It hasbeen in a few animal cells, and in plantcells it is easily observed, the streaming of the cyto-plasm being an example. All animal cells are be-lieved to possess it to a greater or lesser degree. It ismade manifest by the changes in the form of thecN-toplasm, by the movements of the microsomes,and i)y the changes in the position of tlie luicknis. Ameboid movement is similar to that exhibitetl bythe unicelhilar organism, the ameba. Tliis phenom-enon was described first by Rosenhof, in 1755, inthe protens animalcule. Nearly all animal cells.
