In Organic Liquids.—Corrosive sublimate may be sometimes ob-tained by decantation as a heavy sediment from the mucous and bloodycontents of the stomach or the matters vomited.

Unlike arsenic, corrosive sublimate insolution is precipitated as an insoluble compound by many organicprinciples, such as albumen, fibrin, casein, mucous membrane, also bygluten, tannic acid, and other vegetable substances. Thus, then, wemust not expect to find it in all cases in a state of solution in the PROCESS FOR SEPARATING THE POISON. 373 stomach. After removing the mineral sediment, we may separate anyof these insoluble compounds, reserving them for further analysis. As a trial-test for the presence of mercury in solution in the organicliquid, we may employ copper gauze or foil. A small portion of liquidacidulated with one-fourth

Chloride of tin added to a solution of corrosivesublimate, produces at first a white and then a black precipitate which,after it has been boiled, is resolved into globules of metallic mercuryeasily separable by filtration.

It is probable that some unexplained cases of illness or death fromirritation of the stomach and bowels, simulating chronic irritant poison-1ing, may have been the result of eating trichinous food.
