    A parcel of it was subjected to evapora- tion, with some expectation of obtaining a saccharine extract. To my great surprizes when the heat rose to 160° of Fahrenheit, the fluid became uniformly opaque and white, and a considerable precipitate took place, which, when strained, but not much dried, amounted in weight to more than half an ounce, from two quarts of urine, or about one ounce from the quantity dis- charged daily. A similar effect was produced by nitrous acid. The filtrated liquor on evaporation gave a very small extract, which did not contain any saccharine matter. Dr. Latham, after exhibiting a few laxa- tives, which seemed to answer their purpose well, proceeded to the use of astringent me- dicines, and a blister to the loins, but with- out any good effect. This patient quitted the Hospital, after re- maining there about three months, and six weels afterwards he died. M
