Mr. President And Gentlemen:—The importance of this sub... more »ject is so well known to you, and the matter has been so admirably presented by Dr. Salmon in his report read yesterday, that I will not detain you with preliminary considerations, but will plunge at once in medias res. We will take up the subject from three standpoints: First, direct experimental transmission of tuberculosis from man to animals; second, clinical evidence of its transmission from animak to man; and,third, theoretical considerations. In that order I will discuss the subject. First. The transmission of the disease from man to animals is susceptible of direct experimental proof, and it will take but a few minutes to dispose of this phase of the subject. Chauveau was the first in 1868 to prove the possibility of infecting cattle with tuberculosis from man. His experiments were carried out on animals selected from the Jura Mountains where tuberculosis was not known. Consequently the objection which has been raised that these cattle were possibly not free from tuberculosis because the tuberculin test had not been made, does not hold good. Tuberculin had not been discovered at the time of these experiments, but Chauveau took the precaution of selecting his animals from a district in which tuberculosis had never been known, just as at the present time in certain districts in our own country no case of tuberculosis has ever been seen. In 1879, Bellinger succeeded in transmitting tuberculosis of man to cattle, and of others who have made similar experiments I may mention Klebs, Crookshank, Kitt, Sidney Martin, and more recently since the publication of Koch's paper in 1901, Thomassen, Nocard, de Jong, Arloing,...« less
