The content of total sulphates was almost 123 per cent in the hypothet¬ 
ical mean sample of period II as compared with the same of period I. 
COMPOSITION OF SEEDS 
The composition of the pumpkin and squash seeds (less the hulls) which 
were used during period II of this experiment is given in Table IV.

The low water content was due to the fact that the kernels were 
roasted. The high percentage of fat and protein keeps the same relation 
to the water content in raw seeds. 
Comparing the results shown in Tables I and II, it is noted that not 
only the volume of kidney excretion during the experimental diet period 
is considerably less than that during the basal diet period but also the 
amount of total solids is about 5 per cent less in the former as compared 
with the total solids calculated for the excretion during the basal diet 
period. The marked differences are well illustrated in the supplemen¬ 
tary Tables V and VI.

Since a slight increase or decrease in the output of urine, so far as 
volume is concerned, is not of great significance, the determination of 
the creatinin and total nitrogen, as found in the samples of periods I 
and II, was made. The results and comparison of both periods relating 
to the output of creatinin and total nitrogen is shown in Tables VII 
and VIII. 
The data presented in these tables clearly indicate not only that the 
volume of urine and the amounts of total solids excreted during the 
experimental diet period were considerably less than during the basal
