By Prof. James Ritchie. Introductory.—The study of the pathology of infection in the widest and most scientific sense of the tvord is almost, if not quite, conterminous with the study of the effects of any foreign living agent when it gains a foothold — and especially when it multiplies — in the animal bod3^ Another great truth has also emerged in modern times in the recogni- tion of the fact that notwithstanding the diversity of clinical tjqies produced by different agents, there is a great unity in the morbid pro- cesses set up. ^Ye must therefore, in taking a broad view of the subject, be prepared to account for observed facts, and to recognise common processes in such varied conditions as the following:— (1) The action of parasitic fungi and bacteria in such diseases as favus, septicaemia, tuberculosis, diphtheria, enteric fever, etc. (2) The action of parasitic protozoa in such diseases as malaria, tsetse-fly disease, etc. (3) The action of what for the present are called “ultra-microscopic'’ living agents in such diseases as pleuro-pneumonia and foot-and-mouth di.sea.se in cattle, and probably yellow fever in man. (4) The action of parasites of unknown character, though probably belonging to one or other of the last three groups, which are in all likelihood associated with such diseases as small-pox, scarlet. fever, hydrophobia, mcjisles, and so foith. (o) It is a question whether certain phenomena associated with the presence of parasitic worms in the body ought not properlj' to be classed along with the phenomena of undoubted infections. Most of our knowledge regarding the pathology of infection has been derived from the study of the Ijacterial infections of known origin, and in the following article these will form the chief basis for discu.ssion. It is unncccssjiry to enter into any details regarding the nior])holog3’
