Mr. T. Andrews's Chemical Researches 



than I should have wished, seem to me to warrant the general 

 conclusion, that the composition of the blood does not differ 

 from the normal state during the early stages of the disease. 



In order to show more clearly the changes induced in the 

 blood by cholera, I shall collate the results of my own experi- 

 ments with those obtained in the analysis of healthy blood. 



Serum. 



The analysis of healthy blood is Dr. Marcet's, which 

 closely agrees with those of Berzelius and Lecanu. A glance 

 at this table is sufficient to show that in the serum of cholera 

 blood, the albumen is in great excess, but that the salts arc 

 both qualitatively and quantitatively the saitie, the minute differ- 

 ences in their proportions being less than analysts have found 

 in healthy blood*. 



Blood. 



• It may not be uninteresting to obsferve here, the striking analogy be- 

 tween these conclusions and those of Dr. Marcet ; who found in the ana- 

 lysis of dropsical fluids, that however great the variation of albumen, the 

 proportion of salts was invariably the same as in the serum of blood.
