It is likewise a common constituent, either as the free acid or as a urate, of urinary or renal calculi and of the so-called gouty concretions. From acid urines, uric acid is frequently deposited, on standing in a cool place, in the form of a reddish yellow sediment, nearly always crystalline. Chemically, it is composed of carbon, hydrogen, nitrogen, and oxygen, C5H4N4O3, and by decomposition yields urea, among other products. It can be made synthetically by heating together urea and glycocoll. It was formerly called also lithic acid, in allusion to its occurrence in stone, or calculus.
[ Webster]

Urim (?), n. [Heb. �rīm, pl. of �r, fire �r light.] A part or decoration of the breastplate of the high priest among the ancient Jews, by which Jehovah revealed his will on certain occasions. Its nature has been the subject of conflicting conjectures.

By gazing steadfastly on these, he may have been thrown into a mysterious, half ecstatic state, akin to hypnotism, in which he lost all personal consciousness, and received a spiritual illumination and insight.

[ Webster]

☞ In man, the urine is a clear, transparent fluid of an amber color and peculiar odor, with an average density of 1.02. The average amount excreted in 24 hours is from 40 to 60 ounces (about 1,200 cubic centimeters). Chemically, the urine is mainly an aqueous solution of urea, salt (sodium chloride), and uric acid, together with some hippuric acid and peculiar pigments.
