THE BLOOD. 
different species of animals. In most animals the blood corpuscles have 
a relatively large proportion of potash salts and phosphates, whereas 
the preponderating salt in the serum is sodium chloride. In the bullock, 
however, this salt also occurs in large amount in the corpuscles.

In the pig's blood analysed, there were, in 1000 parts, 436 - 8 corpuscles, and 
563 - 2 serum. 
In the horse's blood analysed, there were, in 1000 parts, 531-5 corpuscles, 
and 468 '5 serum. 
In the bullock's blood analysed, there were, in 1000 parts, 318-7 corpuscles, 
and 681 - 3 serum.

Gases of the blood. — Arterial blood of the dog contains from 15 to 
25 vols, per cent, oxygen (at 0° C. and 760 mm. pressure), 25 to 40 car- 
bonic anhydride, and about l - 8 vols, per cent, nitrogen. Venous blood 
of the same animal contains from 5 to 15 vols, per cent, oxygen, 38 to 
52 carbonic anhydride, and also about 1/8 vols, per cent, nitrogen.- The 
proportions of these gases and the manner in which they are combined 
with constituents of the corpuscles and plasma is discussed elsewhere. 3
