140 Mr . W. Brande’s Observations on the Effects 
persevered in its use for six weeks without intermission ; his 
urine was several times examined during that period, and 
contained no superabundant uric acid, and he has not had the 
slightest return of his complaint, although he has put himself 
under no unusual restraint in his mode of living. 
CASE III. 
About the middle of October 1808, a gentleman, forty- three 
years of age, after taking violent horse exercise, was seized 
with pain in the right kidney and ureter. In the course of 
the night he passed a small uric calculus. For some months 
previous to this attack, he had felt occasional pain in the kid- 
ney, but had never voided either calculi or sand. His urine 
was now always turbid, and occasionally deposited red sand. 
On the 28th of October he began the use of soda water, 
and for a time, his urine was much improved in appearance, 
but the uric acid gradually returned, and at the end of De- 
cember, notwithstanding the continued use of the soda water, 
he voided more sand, and his urine was more loaded with 
mucus, than it had ever been before. 
In consequence of these symptoms, on the 3d of January 
1809, he was directed to take twenty grains of magnesia 
every night. 
The urine was examined after the third dose, and the de- 
posit of red sand was diminished in quantity, but it did not 
disappear entirely, after the magnesia had been taken for three 
weeks. 
About this time (on the 26th of January) he caught cold, 
and his urine was again very turbid, but this was found to be 
wholly the effect of mucus, and the symptom soon left him..
