The weight of evidence being in favor ofKocKs views, they have been adopted, with a mention of the results of other observers. ^NOTE BY THE TRANSLATOR. PLATE 85. iiih. ^öch. Cholera Peyers microscopy. MICROSCOPY OF THE STOOL. 179 Drinking-water is the usual carrier of the infection. The ba-cilli do not leave the intestine to pass into the bfood ; they do noteven penetrate the mesenteric glands. Koch explains the fatalaction as a kind of poisoning of the system caused by the changesof nutrition induced by them. Similar organisms have been discovered under different circum-stances. So by Lexois in the saliva, by Finckler and Prior incholera nostras; but they do not seem to respond to the character-istic culture-proof of the comma-bacilli of Koch. Emmerich dis-covered other bacteria, said to be peculiar to cholera, in additionto the comma-bacilli, thus not excluding the latter. KocKs discovery has practically the following advantages: 1. It renders an early diagnosis possible, with consequent ad-vantages to hygienic measures. 2. It establishes the fact that the infection dies when in a drycondition.
