The science and practice of medicine . ar sand of a golden lustre, sometimes mingled with blood-discs; and generally the deeper the color of the urine the darkeris the uric acid sediment. Its appearance does not necessarily in-dicate that an excess of uric acid is forming in the body. The urineis generally yellow and transparent, and the acid is deposited slowlywithout admixture of urates. Liquor potassfe, and also nitric acidin excess, dissolve uric acid. 3. Sediments of Hippuric Acid.—Owing to the solubility of thisacid its sediments are rare. When it does occur, it is in the shapeof long four-sided, acuminated prisms, or acicular needles fixed onuric acid crystals, with which they are sometimes confounded, aswell as with phosphates. They are distinguished from phosphatesby being insoluble in acids; and from uric acid they may be sepa-rated by boiling with strong alcohol (Parkes), 4. Sediments containing Phosphoric Acid are formed of the amnio-niaco-ma/jnesian •phosphate^ the phosphate of lime^ and the phospli/ite of. * The most usual forms of uric acid sediment, with blood-corpuscles intermixed(after Dk.
