on the Blood of Cholera Patients. 301 



vomiting, but who afterwai'ds recovered. I did not see them 

 myself, and therefore cannot be certain whether they were real 

 cases of cholera or not : the specimens resembled in every 

 respect healthy blood. The sp. gravity of the serum of one 

 was 1-024.3, and of that of the other 1-0232. The latter was 

 subjected to analysis ; it contained. 



Water 919-99 



Albumen 71*62 



Salts 8-39 



1000-00 

 The serum was to the crassamentum in the ratio of 51-3 

 and 48"7j and the latter contained 74; per cent, of serum. 

 Hence the blood was composed of, 



Water 80-35 



Albumen and salts • . . 6-99 

 Red globules 12-66

 Specimen 6. Bally macarrett Hospital. — This was taken 

 from a female (aet. 45), who had been affected with violent 

 purging and vomiting. The pulse was feeble when the blood 

 was drawn, but she did not fall into collapse. The blood co- 

 agulated as usual. 



Scruvi. — Sp. gravity 1-031 ; very pure. It consisted of, 



Water 891-69 



Albumen and salts . . . 108-31 



1000-00 

 Crassamentum. — The fibrin in this case was determined by 

 agitating a separate portion of the blood with a network of iron 

 wire, and was thus readily obtained pure, and found to be -296 

 per cent. The blood contained, 



Water 77*93 



Albumen 9*43 



Red globules 12*34 



Fibrin -30 



100-00 

 In three other cases of incipient cholera the serum was 

 found to have the following specific gravities. 

 Sp. gravity . 1-027 

 1-030 

 1-033 

 The last was from a very well marked case. These experi- 

 ments on the blood of incipient cases, though less nunieious
