This deposit is observed on the sides of the glass as well as at the bottom : and the particles vary greatly in point of size, not only in different urines, but in the same sample—from mere dust to coarse sand ; when in a fine state of division, uric acid resembles lateritious urates in appearance, but is readily dis- tinguished by warmth failing to dissolve it. Urines that deposit uric acid are always acid—often per-acid. The clinical significance of Uric Acid de- posits.—The precipitation of uric, acid sand is definitely pathological, if it takes place befoire the urine is voided—the uric acid crystals being discharged with the urine —or as the urine cools. It implies acidity of the urine, and, as a rule, a lower density
