THE BLOOD. 21 5 



analyses of human blood as a whole the following may be 

 taken as best illustrating the mean composition, in 1000 parts.

The individual analyses from which these means are taken 

 show rather wide variations. Some more recent analyses 

 made in Bunge's laboratory show the distribution of the min- 

 eral matters and may be quoted, the figures here given refer- 

 ring to the blood as a whole.

These figures do not show the distribution of the salts be- 

 tween the plasma and corpuscles. In the original analyses 

 from which they are calculated by far the larger part of the
