Cholera - Lecture Delivered at the Homœopathic Medical College of Pennsylvania, December 8th, 1865 #255576

The popular mind is prone to inquire about the existence of certain things or entities, rather than their quantitative relations; it asks, is there infection in this disease or in that? It does not think to inquire whether there is more or less infecting power; it does not suspect that this is the only difference in many diseases with regard to their power of propagating themselves.
