Its aggregation and colour: whether it be amorphous or crystalline, light or heavy; the manner of itssubsidence or precipitation. 9. Its solubility or insolubility by heat; solubility in nitric acid, in acetic acid, in liquor potassse; insolu-bility in both acids and By the microscope :—absence or presence of crystals,their appearance and form; of epithelial cells—renal or extra-renal; of blood disks ; pus globules ;spermatozoa ; fibrinous cylinders; confervoid vegeta-tions, & Fig. 1.

Six-ounce graduated 15. Small flask. These may be conveniently arranged together for use on acircular stand of two tiers, as represented at E.* A microscope is, of course, essentially necessary. It shouldbe provided with a first-class i-inch object-glass, and an eye-piece to magnify not less than 240 diameters. III.—EXTRANEOUS MATTERS IN U
