    b. A second portion is to be treated with one or two drops of a solution of sulphate of copper CuO,S03 + 5Aq., and afterwards a considerable excess of potash KO,HO is to be added. The dark blue solution is then to be heated over the spirit-lamp and boiled for a moment, when a yellowish brown precipitate of suboxide of cojjper CugO, will be produced [Trammer's test] (§ 277). c. A third portion is to be heated with about an equal bulk of the solution of tartrate of copper in potash, Barreswil's solution (§ 278). d. Fermentation.—Fill one of the tubes placed on the table with urine, and the other with water, to each add six drops of yeast, and then a little more urine and water, in order that the fluids may rise above the brim of the tubes. Apply the india-rubber pad, and invert them in the small beakers. Remove the india-rubber, and add some mercury. Place the whole in a temperature of 80°, and, after the lapse of two hours, compare the size of the bubbles of gas in the respective tubes (§ 283). e. Crystals.—Allow a few drops of diabetic urine to evaporate spontaneously upon a glass slide, and examine the residue on the next day to see if crystals have formed (§ 274, Plate XIIL, Fig. 66). 29. Bile.—a. One portion of the urine is to be placed in a test-tube, and after the addition of one drop of syrup, two-thirds of its bulk of strong sulphuric acid SO3HO are to be added cautiously by drops. Shake the mixture, and allow it to stand for a few minutes. If sufficient heat is not produced by the addition of the acid, warm the tube slightly over the lamp. The mixture becomes of a dark violet colour, which, however, is destroyed by a tempera- ture a little above 140*' [Pettenkofer's test] (p. 144). b. Pour a few drops upon a clean white plate, and after spreading it over the surface, allow a drop of nitric acid to fall in the centre. Observe the play of colours (§ 258 a). c. To another portion add a few drops of serum, and, after agitation, a little nitric acid NOsjHO. Observe the colour of the coagulated albumen [Heller's test] (§ 259).
