Itis apt to be deficient in urea, though it may contain urates or urine contains a large amount of grape sugar, for the detection ofwhich several methods have been recommended, the following are amongthe best:—1. Trommels test.—Add a few drops of a solution of Sulphate ofCopper to the urine, enough to give it a pale blue tint, (a pale blue Phos-phate of Copper may be precipitated); now add an excess of Liquor Potassa,if sugar be present, a purplish-blue solution is formed, and if the mixturebe carefully boiled for a few minutes, a reddish or yellowish-brown precipi-tate ensues ; if no sugar, a black precipitate. 2. Moores test.—Add to theurine about half its bulk of pure Liquor Potassa, and boil gently for a fewminutes; if sugar be present, the liquid will assume an orange-brown, or DIABETES. 437. bistre tint. 3. Horsleys test.—Mix together equal parts of Neutral Chro-mate of Potash and Liquor Potassa. Place a small quantity of this test insome urine in a test tube, and boil; if sugar be present, a deep sap-greencolor will ensue from the decomposition of the Chromic Acid; the reducedOxide of Chromium is held in suspension by the Potash. To test canesugar, substitute a solution of the Bichromate of Potash for that of theNeutral Chromate. 4. Lutons test.—To a cold saturated solution ofBichromate of Potassa add an excess of Sulphuric Acid in such amanner that some free Sulphuric Acid will Fi 30 be present when all the Chromic Acidis liberated. The liquid will be of a beau-tiful limpid red color, and is composed ofwater, Chromic Acid, Bisulphate of Potassa,and an excess of Sulphuric Acid.
