Secretions underffo during Cholera Morbus. 



131 



Mr Hermann states, that he found blood taken from the right 

 ventricle of the heart of a patient dying of cholera, very firmly 

 coagulated. When shaken a little, this blood became fluid, and 

 quite homogeneous. Viewed in the microscope, no globules 

 could be perceived in it. 



Mr Hermann sought for urea in the blood of cholera patients, 

 but in vain. No trace of it was discoverable. 



Analysis of Watery Fluid vomited hy Cholera Patients.—^ 

 This fluid is described by Mr Hermann as thick, of a dirty 

 slightly yellow colour, and a sour smell. Its specific gravity 

 varied in different patients, as 1.0060, 1.0055, and 1.0035. 



When allowed to rest tranquil for some days, it becomes 

 clear, while a grey-coloured mucus is deposited in variable 

 quantity. By an analysis detailed by Mr Hermann, the differ- 

 ent steps of which we do not think it necessary to mention, he 

 found that this fluid consisted of the following ingredients : 



Water and mucus, 990. 



Osmazomelike substance, . . , . 6.61 



Salivine, . . 1.04 



Acetate of soda, muriate of soda, with small quantity 



of phosphate of lime and magnesia, . . . 1.56 

 Anhydrous acetic acid, 0.89 



1000. 



A little butyric acid was afterwards discovered.
