Excerpt from Report of the U. S. Board of Inquiry, Concerning Epizootic Deseases Among Swine, 1889The fact that the chemical products developed during the multipli cation Of the germs of hog cholera would create an immunity was first demonstrated by the experiments of this Bureau; and all that is known Of this subject was brought out by these investigations. I have recognized the fact from the time I began the study of swine diseases in the interest of this Department that this was one of the most prom ising lines of research; at the same time it is one Of the most difficult questions to investigate that is now before the scientific world, and the reason our experiments have not been carried further is that we have not had the laboratory facilities for this kind of work.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
