A distinction must be made between the cases in which the microbes themselves find their way into the Circulation, and those in which the chemical poisons alone reach it. In the first instance, that is, where the microbes also reach the blood, we pass by the cases in which there is mere metastasis, as simply repetitions of the original local process. Let us consider only the cases in which the microbes remain at the point of infection, but their chemical products find their way into the blood. What is the result? There is forthwith poisoning with these substances, and we have to deal with local process and fever. Example: acute infectious diseases: (1) croupous pneumonia: local processes in the lung produced by cocci; fever by their chemical products; (2) diph theria: local process in the mucous membrane of the respiratory tract produced by bacteria, fever by their chemical products. [it may be remarked in this connection that the diphtheritic mem brane is probably produced by the union of diphtheria ptomaines with some chemical tissue element of the mucosa] In febrile diseases, in the production of which specific microbes are concerned, the local manifestations are produced by the microbes, which act as living foreign bodies and are treated as such by the organism (inflammation), while the fever is the result of an intoxication of the nervous system brought about by the action of chemical products due to the growth and functional activity of the microbes.
II.' Febrile diseases occurring without the introduction of specific microbes.
