From this table we find that the average daily output of urine during 
Period II was greater than that of Period I but smaller when compared 
with the average daily volume of urine excreted during Period III.* 
The amount of total solids of the experimental Period II was less as 
compared with either of the basal periods (I and II) which served as a 
check in this work. The acidity of the urine excreted during Period II 
was on the average slightly greater than that of Period III which agrees 
with the results obtained in the first experiment.^ 
The total nitrogen output is highest in Period TI due to the fact that 
additional feeding substances, in the form of pumpkin seeds, were added 
to the basal diet. 
Of the nitrogenous ingredients of the average samples of the three 
periods, uric acid of Period II shows a marked relation to that of Periods 
I and III. Namely, taking the average quantity of uric acid excreted 
during Period III as 100%, we find that the average output of uric acid 
during Period II was 128.12%. 
Creatinine of the average sample of urine excreted during Period II 
as compared to that of Period III is as 100% is to 87.97%. The excre- 
tion of urea during Period II was 117%. 
A comparative qualitative test (Obermayer's) for indican of all the 
nine samples of urine gave the results shown in table 6 below :

It is of significant interest to note that the last two samples of the experi- 
mental period and the first sample of the final period gave the deepest 
coloration when tested for indican.
