PIERRE DOZOIS AND FRANK HACHTEL Department of Bacteriology, University of Maryland School of Medicine, Baltimore, Maryland Received for publication May 14, 1935 Although the literature contains numerous references to the effect of heat and storage on the bacterial cell, a careful review fails to reveal any information as to the influence of either on the electrophoretic migration velocities. Recent workers, in their studies of those physical agents which influence the zeta potential, suggest that heat may play a part, but experimental evidence for this has not, to our knowedge, been published. In the various studies on the effect of x-rays and radium on the zeta potential (Dozois, Titsler, Lisse and Davey (1932), and Dozois, Ward and Hachtel (1935)) the question has arisen of the part heat may play in the results obtained. In the determination of the zeta potential of pathogenic microorganisms, using the Kunitz modification of the Northrop-Kunitz microcataphoresis cell (1928)-work now
