Abstract : An investigation was made of the mechanisms by which pattern swimming is accomplished in ciliates and flagellates, including the mechanism of geotaxis. By means of high speed motion pictures, the variations in flagellar movement between several species of flagellates were determined. Furthermore, a new hydrodynamic theory is proposed explaining how spirochetes locomote by means of traveling helical waves. One of our most outstanding discoveries was the fact that the cilia of Paramecium and Tetrahymena beat with a traveling helical wave and not with a back and forth movement as previously believed; however, it was found that Spirostomum does beat with a back and forth movement.
