Abstract
DR. TUTIN is a member of the Institution of Naval Architects, and I accept his statement that the relative speed of Monas stigmatica is only about two hundred times that of a modern destroyer. In the past, the relative speed of living organisms has always been expressed as the ratio distance per sec./length of organism1. It would indeed be interesting if one could measure the revolutions per sec. of the organism; but I fear this is impossible at present, since it could only be done either by the use of high-speed photomicrography or by the use of the stroboscope attached to the microscope.
