It 
This gentleman informed me, that whenever he omitted the 
use of an acid diet, or took much w'ine, especially port, his 
urine deposited the white sand and mucus, for two or three suc- 
cessive days.

aged patient submitted to the operation for the stone within five years,

mucus. 
From the age of this patient, and the account of his case, 
there appeared little doubt that the calculi had been formed in 
consequence of a diseased prostate gland, in the manner de- 
scribed by Sir Everard Home*, and on examining them, they 
were found to contain no uric nucleus, nor indeed had there 
been any symptoms of disease in the kidneys, at any previous 
period. 
This gentleman had been in the habit of taking soda water, 
from which he was now desired to abstain, with a view of 
putting him upon the acid plan of treatment. He was ordered 
to take eight drops of muriatic acid three tjmes a day in two 
table-spoonsfuls of water ,• but the third dose produced so 
much irritation in the bladder, and consequent increase of his 
symptoms, that it became necessary to adopt another treat- 
ment. 
Lemon juice, or a solution of the pure citric acid, w'hen 
given in quantity sufficient to produce any change in the appear- 
ance of the urine, had the same effect as the muriatic acid. 
As water impregnated with carbonic acid could not be pro- 
cured, he was directed to dissolve, in separate portions of water, 
twenty grains of citric acid, and thirty grains of the crystal- 
lised carbonate of potash, and to take the mixed solutions, 
during the effervescence. This quantity was at first only taken 
night and morning, but as it agreed perfectly well, it was 
afterwards repeated four or five times daily. Under these cir- 
cumstances the appearance of the urine was soon improved.
