When vegetable food only is taken the same variations are seen as when mixed diet 
is eaten. The acidity is most before food. The highest acidity was 26*36 measures; 
then the uric acid =0*049 gr. per lOOOgrs. of urine, specific gravity 1024*0. The 
uric acid was most after food; the highest amount being 1*01 gr. per lOOOgrs. of 
urine, specific gravity 1025*6. The acidity then was only 12*67 measures per 1000 
grs. of urine. The variations of the acidity in (9.) are very remarkable. 
For three days in succession animal food only was taken, meat, eggs, cheese, coffee 
and water. Breakfast at 9 a.m. Dinner at a quarter to 6 p.m.

In these experiments also the uric acid is increased after food, and the acidity is 
diminished. The highest amount of uric acid was 1*022 gr. per 1000 grs. of urine, 
specific gravity 1027*8. The acidity at the same time was 18‘48 measures. Previous 
to food the same day the uric acid =0*073 gr. per 1000 grs. of urine, specific gravity 
1027*1 ; then the acidity =24*34 measures. 
Comparing the three days on animal food with the three days on vegetable food, 
we have the highest amount of uric acid on the third day ; in the one case =1*022 gr..
