as will be noticed hereafter. The carbonated alkalies wili 
be likely to prove less injurious than the sub-carbonates, be- 
cause their greater proportion n of acid will tend to prevent 
the deposition of the phosphates in the bladder: but 
at the same time they are Saar inert as the sub-carbonates 
as to the acids* in the stomac 
The preceding oe is "amply confirmed by direct 
experiments, upon € of uric acid, with alkaline —_ 
nates and Eiimverboaates and with magnesia. The result 
(prov. that the use of magnesia greatly relieved or ies 
ly removed the symptoms of uric acid, while the other rem- 
edies produced no such effect. 
I have been led to pay more particular attention to this 
subject, from the circumstance of my own case, which is- 
believed to have been of the nature alluded to, and a suc- 
cinct account of which may serve to shew a practical con- 
nexion between some remarks that have already been, and 
some that are yet to be ma: 
‘During a oteident bie portion of the year 1817, 1 had 
‘ved in a very sedentary manner and for some part ‘of the 
time was unusually abstemious in diet, closely confined in 
the damp walls of a new brick building, which was fre- 
quently neither well ventilated nor warmed. In November, 
I experienced several short and pungent attacks of a pain 
in the right side, and near the region of the kidneys, which 
were removed in a little time by a stimulating potion ; but 
at length, in a few hours after drinking a glass of wine, 
from which I had long abstained, a severe and most distres- 
ing paroxysm came on and continued for several hours. 
Some of the symptoms indicated a violent, flatulent cholic, 
while from others it might be concluded that either rheu- 
“matism, or the passage of calculous matter fron the kidney 
to the bladder was the cause of suffering. le 
eructations took place, there was acute and fixed misery in 
the loin and hip of that side, and frequent shooting and 
aegaatg pains down the right thigh urethra, &e. but 
_ there was no. nausea of the stomach nor fobtile’ affection.
