326 CIRCULATING FLUIDS : 



The blood-corpuscles, therefore, fall beloAv Lecanu's average, 

 while the albumen aud sohd constituents, generally, are consi- 

 derably increased. 



Lecanui has made several experiments upon the quantity of 



sohd constituents in the blood in cholera, and has arrived at 



the following results :

Water .... 660 749 480 670 



0'Shaughnessy2 has analysed the serum of the blood in this 



disease, and has detected a considerable quantity of urea in it, 



1000 parts were composed of. 



Water 854-0 



Albumen 133-0 



Urea 1'4 



Crj'stalline and fluid fat .... 1-4 



Chlorides of sodium and potassium ... 4'0 



Sulphates and muriates 1'6 



Extractive matter and albuminate of soda . 4*8 



I analysed the blood of a woman labouring under a severe 



attack of sporadic cholera. 



1000 parts of blood contained : Analysis 4o. 



Water .... 750-530 



Sohd constituents . . 249-470 



Fibrin .... 2-470 



Fat .... 5-434 



Albumen . . . 114-114 



Heematoglobulin . . 108-529 



Extractive matters and salts 10*631 



The salts amounted to only 5-41, the average quantity being 

 from 7 to 8 in 1000 parts of blood. We see that the water is 

 decidedly diminished, but the ratio of the blood-corpuscles to 

 the albumen is not such as was formerly supposed.^ In con- 

 sequence of the suppression of the urinary and biliary secre- 

 tions, the blood contained a quantity of urea and of the con- 

 stituents of the bile, (bilin and biliverdin.) 



[Heller examined the blood taken after death from the ca- 

 rotids of a man who died of sporadic cholera.

3 It was conceived that the thick and often imperfectly coagulated blood must be 

 very rich in corpuscles, in consequence of the amount of serum thrown off by the 

 intestinal canal.
