Venous blood is always richer 
in extractive and fatty 
matters ; the purification, however, which it undergoes in the’ 
above-named organs, removes them again, so that arterial 
blood contains these substances 
portions, as compared with th 
examination. 
It is also remarkable that this increase, 
extractive matter, was more 
only in very minute pro- 
€ results obtained in this 
especially in 
marked in proportion to the 
time which had elapsed between the first attack and the 
period when the animal was 
killed. I assume here, that 
most of the animals were attacked at about the same time. 
The amounts of fat and extractive matter found in 1000 
parts of the blood of different animals were, on

The qualitative examination 
of the extractive matter 
showed, that it was largely composed of the constituents of 
bile and urine. 
Urine—I have unfortunately not been able to secure so 
many samples of urine as were desirable for a thorough: 
examination,
