Again, "Look at the diseases of the circulation," he says. "The doctors say that digitalis and nitrite of amyl act on the heart; and that the action of these drugs was discovered by the help of experiments on animals. Very good. The heart is concerned with the circulation. Very good. But here are the Registrar-General's returns of the annual death-rate for all diseases of the circulation. See how it has gone up, from 1371 per million persons in 1881 to 1709 in 1900. Therefore, either these two drugs are never used, or they are useless, or the Registrar-General's returns are false." It is impossible to understand how Mr. Coleridge could bring himself to write thus. Digitalis has a certain effect on the heart-beat; nitrite of amyl diminishes arterial tension. The Registrar-General's returns for all diseases of the circulation include every sort and kind of organic disease of the valves of the heart; include also pericarditis, aneurism, senile gangrene, embolism, phlebitis, varicose veins, and 35,499 deaths from "other and undefined diseases of heart or circulatory system." RABIES For rabies, Mr. Berdoe praises the "Buisson Bath Treatment for the Prevention and Cure of Hydrophobia." The virtues of this treatment are proclaimed by the Chairman of the Canine Defence League, F. E. Pirkis, Esq., R.N., of Nutfield, Surrey, and it is founded, we are told, _on the simple common-sense principle that if poison is injected into a person's veins the best thing to do is to get it out as quickly as possible_. This sentence, and the reference to Mr. Pirkis for further particulars, and the fact that there is, or was, a Buisson Bath at the "National Anti-vivisection Hospital," bring us to the question, What is the value of the evidence in favour of this treatment?
