It is certain that no theoretical views conceived by one experimenter are binding, or need even be interesting, to others. What is obligatory is the acceptance of the results obtained. T/tc Plague Prophylactic. In order to accumulate for the plague prophylactic a large amount of extra-cellular toxines, the bacilli are cultivated on the surface of a liquid medium where they are suspended by means of drops of clarified butter or of cocoanut oil. The bacilli grow down in long threads into the depth of the liquid, and produce what I have termed a stalactite growth in broth, an appearance quite peculiar to this microbe, and which, I hope, will be accepted as the specific diagnostic feature of this microbe. The products of their vital exchange--the toxines--are secreted by the stalactites into the liquid and accumulate there. The growth is periodically shaken oIf the surface of the broth, after which a new crop appears underneath that surface. Thus a large quantity of the bodies of microbes is collected at the bottom of the cultivation vessel, and the liquid itself gets gradually permeated with increasing quantities of toxines. The process is continued for a period of five to six weeks, at the end of which the bodies of the microbes become extremely deteriorated. It will be seen from this that, in my eagerness to put to test our ability to influence the case mortality I may have, perhaps, paid less attention than I might have done to the problem of reducing the number of attacks; and I have now sketched out a simple plan whereby to test this circumstance, and to try to improve our results from this point of view. In order to render harmless the inoculation of the virus above described, ...
