As already stated, increasing the pressure does not prevent the flocculation of hydrogen gas. Emulsification, which is due to cavitation, and the cytolysis of cells, especially the laking of blood corpuscles, present many characteristics in common. Since the laking of blood corpuscles lends itself to quan- titative treatment, most of these studies have been made with a suspen-. FIG. 1. Tube for studying flocculation of air bubbles. sion of unwashed turtles' corpuscles containing about 4 X 10° corpuscles per cc. in .65 per cent NaCl in tap water, which will be referred to as blood. A test tube filled with this dilute blood presents the silky ap- pearance due to the optical effect of disk particles and so scatters light that the filaments of an incandescent lamp run at reduced voltage can- not be seen through the blood corpuscle suspension. As laking proceeds and more and more corpuscles are destroyed, the filaments first become visible when about 80 per cent of the corpuscles are destroyed, after 8-20 seconds raying, depending on the conditions of the experiment. Finally all corpuscles are destroyed and microscopical examination shows only nuclei left floating in the fluid. The end point for begin- ning of appearance of the filaments is very sharp under constant con-.
