Show Nature of Infectious Diseases. This discovery of the parasitic naturo of infectious diseases is of more than scientific interest; it is of vast practical value. It has uot yet, perhaps, contril-uted contril-uted very materially to tho mothods of treating disease directly, although we may confidently expect great results in the future along this line. There is nothing noth-ing to prevent direct experiments with germicides upon living bacteria in the laboratory, and we may hope in this way to get a more scientific method of curing Infectious diseases, after the theory of their parasitic nature becomes moro truly the property of doctors as well as scientists. scien-tists. Thus fur, however, the value of the theory has been rather as the foundation founda-tion of tho science of preventive medicine. Here its importance cannot be overrated, and isonlp beginning to become realized. II. W. Conn in Science. |
