DR. BENCE JONES ON THE VARIATIONS OF THE ACIDITY 
grains of carbonate of ammonia were taken at 11^40^a.m. The same quantity at 
]h j 5 m repcatod at 2^ 25™, 
and again repeated at 3'* 55™. In all, eighty 
grains dissolved in about eight 
ounces 
of distilled w-ater.

‘ Plate LIII. gives the means 
of comparing the acidity of the 
urine on these days. 
Here also it is evident that th 
e acidity is not so much diminished after food when 
carbonate of ammonia is taken, but 
the increase in the acidity after the volatile 
alkali is taken is not so evident as in the previous Plate LII. : this probably arose 
from the very considerable increase in the quantity of water 
made on the day the 
carbonate of ammonia was last taken. 
The volatile alkali acted as a diuretic. This 
is seen by the lower specific gravity of the urine the second day. The actual quan- 
tity of water passed was one-third more than it was on the previous day. 
Still this experiment shows 
that eighty grains of carbonate of ammonia do not 
lessen the acidity of the urine. 
(49.) The following day no carbonate of ammonia was 
taken. Breakfast at 
8^ 20™ a.m. Dinner at 7^ 15™ p.m. An increased quantity of urine was secreted during 
this day also.

(50.) The next day eighty grains of carbonate of ammonia were taken in divided 
doses : twenty grains at iT* 45"^ a.m. ; the same quantity at T' 15™p.m., at 2*’ 30™ p.m., 
and at 3’* 45™ p.m. Breakfast was at 8^' 20™ a.m., and dinner at 7^" 30™ p.m. 
The quantity of urine was much less than on the two previous days.
