![A REPORT ON THE ^ MICROSCOPIC OBJECTS FOUND IN CHOLERA EVACUATIONS, ETC. BY T. E. LEWIS, M.B. lOf Date April, 1870.] In accordance with instructions issued at the commencement of this inquiry, attention has been specially directed towards obtaining facts bearing on the truth or otherwise of two hypotheses regarding the cause of cholera—namely, the theory of its fungoid origin, particularly the one advanced by Professor Hallier of Jena; and the theory of the connection existing between cholera and certain conditions of the soil, promulgated by Professor Max von Pettenkofer of Munich. In both theories the existence of a specific poison of an organised nature is maintained—a ,(/erm; and both savants believe it to exist in the alvine discharges of a person affected with cholera. The Munich Professor does not risk an opinion as to whether it belongs to the animal or to the vegetable kingdom, but infers that the soil is the nidus in which it grows ; whereas Professor Hallier maintains that it multiplies in the human body, and unhesitatingly affirms it to be a fungus. An account of the observations which have been made in order to test the views advanced by Professor Hallier will occupy the first portion of the report; and, as in the course of the investigation my attention has been directed to a consideration of the microscopic objects which are found in the evacuations of cholera patients, a description of them will at the same time be given; together with illustrations of various initiatory experiments bearing on the general question of disease-germs. [The second portion of the report mainly deals with Professor Pettenkofer's theory.]](https://iiif.wellcomecollection.org/image/b21296996_0039.jp2/full/800%2C/0/default.jpg)
