H—Cl. tetani; A—C. diphtheriae; \ |— Cl. perfringens; Q—M. aurens; A—B. cereus; O—Sea water; |—Sir. pyogcnes; V—Cl. sep- ticum. These data are not conclusive since the heated toxins apparently had an effect similar to that of the toxins. However, it is interesting to note that the effects of these toxins on the eggs are in many respects the same as those on erythrocytes. In the case of Arbacia eggs, the toxins from C. diphtheriae, Cl. tetani, and M. aurens accelerate respiration. The significance of the lack of inhibition by the streptococ- cal toxins will be discussed in a future publication. In the case of Asterias eggs, the tetanal toxins clearly accelerate respiration; the diphtherial and staphylococcal tox- ins may accelerate slightly for the first hour or two; the perfringens toxins may ac- celerate slightly, while there is a suggestion of a delayed acceleration in the case of the toxins of B. cereus. The streptococcal toxins and those of Cl. septicum inhibit respiration. DISCUSSION A comparison between these data and those previously reported (Hunter et al., 1949a, b) shows that in general the action of the toxins on the four types of cells.
