twice a day, the same equivalent of antimony, and at the end of the 
17 days the one rabbit had taken 2°34 grams of tartar emetic, the 
other 1:08 grams of antimonious oxide. While each rabbit had 
taken the same amount of antimony, the one which had taken it in 
the form of potassium antimony tartrate was much more severely 
affected by the poison. In this case there was severe purging and 
finally death on the 17th day. In the case of the rabbit fed with 
antimonious oxide, the only apparent effect of the poison was a loss 
of appetite and great thirst. This animal was killed with chloro- 
form on the death of the first rabbit. Both forms of antimony were 
administered as powders, by way of the mouth, in small gelatin 
capsules. 
Following are the results of the analysis of the various parts

Looking at these results and remembering that each animal re- 
ceived the same amount of metallic antimony, it is evident that 
tartar emetic is much more completely absorbed than the oxide. 
With tartar emetic, however, the results are not exactly in accord 
with the previous ones, obtained with this salt; thus the amount of 
antimony absorbed by the brain is far smaller proportionally than
