1S2 Mr Hermann on the Changes the Animal 



In the three specimens of the fluid which were examined, the 

 quantity of acetic acid varied considerably. In 1000 parts of 

 the fluid, of specific gravity 1.006, there were 1.204 parts of 

 acetic acid ; in that of specific gravity 1.0055, 0.942 parts ; and 

 in that of specific gravity 1.0035, 0.513 parts. 



A very superficial glance at the results of this analysis of the 

 vomited fluid, is suflicient, according to Mr Hermann, to shew 

 its analogy with gastric juice. 



Analysis of the Watery Excrement of Cholera Patients, '-' 

 The fluid excrement passed by cholera patients, Mr Hermann 

 describes as turbid, slightly and dirtily coloured, and possessing 

 a peculiar fetid odour, derived from the large intestines. When 

 the fluid stands for some time, it does not become wholly clear, 

 like that passed by vomiting. It is generally acid, both in its 

 chemical properties and taste, as ascertained by Dr Reuss. 



The fluid passed by stool resembles much in its chemical con- 

 stitution that which is vomited. It contains a free acid, in some 

 instances in considerable quantity, which is acetic ; also butyric 

 acid. The chief animal principles which it contains are mucus, 

 albumen, salivine, osmazome-like substance, and a small quan- 

 tity of picromel and resin of bile. 



In the body of a man who died after having been affected 

 twenty-four hours with cholera, and who had been purged with- 

 out vomiting, the fluid in the stomach was found to be exactly 

 the same as that vomited by other patients. In the duodenum 

 the fluid resembled much that in the stomach, though it was not 

 so sour. In the large intestine the fluid had the fetid smell of 

 excrement, and was darker in colour, and more acid than the 

 fluid in the stomach or duodenum. 



Analysis of the Urine of Cholera Patients. — Mr Hermann 

 states, that, as the urine is generally very much suppressed du- 

 ring cholera, he had no opportunity of examining this fluid at 

 the time when the disease was at its greatest height. ^ 



The urine which he analyzed was procured from a person 

 who survived the attack of cholera. It was the first passed after 

 the suppression. It formed a turbid yellowish fluid, which gave
