Drinking water contain- ing this air may impregnate the urine with it, and make it more efficacious in diflblving calcareous matters than it would otherwife be. * The drinking of waters impregnated with fixed air is recommended and extolled by Hoffman and others, as very efficacious in preventing and diflblving cal- culi. Human calculi, by being macerated in thefe waters, were confiderably diminifhed. They are alfo diminifhed by immerfion in the urine of thofe perfons, who had drunk water impregnated with fixed air; while the urine of aperfon in health, not ufing fuch water, had no effect in leffening their bulk.j From this fact the inference muft certainly be drawn, that fixed air is conveyed unchanged into the urine. Doctor Sydenham entertained the idea that malt liquors alleviated the pain and irritat ion arif- ing from gravel. In his own cafe, he obferves, that whenever he was obliged to ride over flones, it was his cuftom to take one or two large draughts of fmall beer, which prevented bloody urine.
