discoveries of the utmost value to the whole animal kingdom (N.B., man included) have been gained, may be of interest to your readers as well as infor- mation to Dr. Hadwen. From the blood or tissues of man or an animal suffering from a disease repeated cultivations are laboriously made by Pasteur's methods in a bacteriological laboratory until any microbe which may be present is obtained growing actively and in pure culture—i.e., alone and uncontaminated by the concurrent growth of any other microbe. The culture of such microbe is then injected hypodermically or into the circulation of a normal animal. If this animal develops the symptoms of the disease, and if from its blood or tissues the same microbe is again obtained in pure culture, that organism is accepted as being the parasite which causes the disease. VICTOR HORSLEY. [From The Daily Mail, September 16.] DR. HADWEN. Sir,—Sir Victor Horsley has evaded every point in my challenge for proof of his statements, and has avoided all reference to the points in which I definitely showed him to be inaccurate. He professes to deal with one point and one point only—namely, that which concerns the germ theory of disease—by quoting the technique of microbe culti- vation based upon the postulates of Koch. This is not an answer to my challenge, and his conclusions are again inaccurate, as I will show. Koch's postulates are as follows : (1) The alleged specific micro-organism must be found in the disease of which it is supposed to be the sole cause. (2) It must not be found apart from the disease it is supposed
