CONTRIBUTION TO OUR KNOWLEDGE OF TUBERCULOSIS ANTITOXIN.

It is very probable that in the future the serum of geese will prove to be a very efficient toxin-carrier Injections (intraperitoneal) of high doses of TBET, etc. (from human tuberculosis) act in them, stimulating to a much higher degree; antitoxin is readily produced and accumulated. I shall report as to my experiments in this line, as well as a series of experiments with the serum of a number of immunized horses, in another paper. I will only mention here that I can fully substantiate my former conclusions by repeated investigations, although I must admit that a number of animals reported on in my previous paper afterward died; some of them succumbed to a very slow form of tuberculosis, while others died from intercurrent diseases, mostly intestinal adhesions and constrictions following the injections. Still, a great number have survived until today, and have repeatedly propagated and given life to several
