The oriental bezoard, a resinous intestinal calculus, chiefly met within certain species of goats and deer, appears (like ambergris in the whale) to be the result of morbid secretion from the bowels of the animal, and not to be composed (as was imagined by Vauquelin) of materials derived from its food. A very doubt- ful case of calculus occurring in the human intestine, with close resemblance to ambergris in its characters, has been published by Dr. Kennedy.* We have lately examined some masses composed solely of fibrin, (Univ. Coll. Mus. presented by Dr. Rayner,) passed from the rectum after prolonged sufferings, simulating those of cancerous disease. (£.) Biliary, (Gall stones, Choleliths).— Biliary calculi are found in every part of the system where the bile circulates, and even make their way occasionally into localities in which that fluid is not naturally found. Most com- mon in the gall-bladder, they are frequent in the larger ducts ; far less rare than has been affirmed by some writers in the radicles of the hepatic duct, not uncommonly encountered in their transit through the different parts ofthe intestine (where it is possible they may be sometimes actually formed), they are very rarely seen in the stomach. Biliary calculi vary in number from one to several hundreds and even thousands : 3,646 are said to
