230 CIRCULATING FLUIDS : 



The analyses of Denis, (althougli from the very different 

 manner in which they were conducted, their results cannot 

 very well be compared with mine,) upon the whole, support my 

 statements with regard to the proportions in which the most 

 important constituents occur. 



I shall give some of his analyses in a condensed form, re- 

 ducing them to the relative proportions of water, solid residue, 

 fibrin, blood-corpuscles, and albumen. 



The venous blood of healthy men contained in 1000 parts : 



In my observations on Denises method of analysing blood I 

 pointed out the reasons why some of the constituents would 

 not be correctly determined. It is obvious that, in these 

 analyses, two of my characteristics of healthy venous blood, 

 namely, the proportions both of the solid constituents and of 

 the blood-corpuscles are given in excess. I fix the proportion 

 of the solid residue by an exact determination of the water, at 

 about 20J5, whereas these analyses would bring it up to 26-85. 

 Still greater discrepancies occur in the relative proportion of 

 the albumen to the blood-corpuscles. In my analyses the pro- 

 portion of the albumen to the hajmatoglobulin (the principal
