410 Chittenden and Cummins—Influence of some Organic 
or lower tube (a), while the remainder was used in the two other 
tubes b and c. Several solutions of oxalic acid were employed, the 
average strength of which was such that 1 c. c. equaled about 20 
milligrams of carbonic acid. ;

Action of uranyl! nitrate. 
As stated in a preceding article,* the physiological action of ura- 
nium salts has been little studied. Experiments are now in progress 
to show the influence of uranium on proteid metabolism, and our 
present results show the influence of this substance on the excre- 
tion of carbonic acid. The rabbit first experimented with was de- 
prived of food for three days, and on the fourth day the experi- 
ment was commenced, extending through three entire days, during 
which time the animal was without food. The accompanying tables 
show the results obtained. The body temperature was ascertained 
by inserting a self-registering thermometer into the rectum.
