in consequence of the use of such remedies : the time which 
has elapsed since the cure of this and other cases, □ without a 
relapse, is also strongly in favour of this mode of treatment. 
Case 2 A gentleman, twenty years of age, who had suffered 
from heartburn, and other dyspeptic symptoms, was seized, 
on the 1st of June, 1811, with a violent pain in the loins, and 
more especially in ihe right kidney ; and during the night he 
passed a large quantity of r-d sand with his urine. On the 2d, 
with a view to relieve the pain, which had increased consider- 
ably, he took fifqy drops of laudanum, and drank freely of 
barley water. The night was passed more quietly ; but on the 
morning of the 3d, he was seized with a violent pain in the 
kidney, and with the usual symptoms of the passage of a cal- 
culous along the ureter. These continued, with more or less 
violence, till the evening of the 4th, when he became perfectly 
easy, and remained so till the morning of the sixth, when, with 
considerable pain and difficulty, he voided a calculous composed 
of uric acid, weighing nine grains. For several successive days 
bis urine deposited a large quantity of red sand, and three very 
small round calculi were voided. 
He w'as now directed to abstain from all kinds of fermented 
liquors and sour food, and to take a pint of treble soda water, 
(containing three drachms of sub-carbonate of soda,) daily. 
Under this treatment he continued to recover, and remained 
perfectly free from complaint until the end of August, when 
a copious denosit of red sand appeared in his urine : he had 
little pain in the affected kidney, but complained of almost 
constant nausea, or want of appetite. The soda water was 
increased to a pint and a half, and afterwards to two pints 
daily, and in the intervals, he drank very freely of barley 
water. 
Having persevered in this w-ay for ten days without receiv- 
ing any benefit, he was induced to make a trial of magnesia, 
of which he took one tea-iponnful night and morning in cold 
chamomile tea. In about a week the state of his stomach was 
much improved, and the deposit in the urine proportionally
