Excerpt from The American Practitioner, 1879, Vol. 19: A Monthly Journal of Medicine and Surgery This deposit seems to the naked eye formed of small, gran ular, adherent, Opaque masses, Of a Semi-crystalline character, and sulphur-yellow color; but viewed with a microscope by reżected light, the small nodules are seen to be composed Of a great number Of minute hexagonal prisms, sharpened at the ends, and grouped together in the form of a rosette, making a beautiful specimen for preservation. It is not freely soluble in cold water, but hot water dissolves it readily, and it is not precipitated on cooling; it is also soluble in alcohol. Its solu tion is neutral to test-paper; it is odorless, but is intensely and peculiarly bitter to the taste; it produces no discoloration in solution Of starch. I at first thought it probable that this deposit was a double iodide Of cinchonidia and potassium; but when a portion of it was carefully heated on platinum foil over a spiritlamp, it melted, turned dark', emitted fumes, swelled up, becoming a porous mass of charcoal, which finally entirely disappeared under continued heat, leaving no ash or residuum. The absence of potassium was also proved by adding tar taric acid to a solution of the yellow deposit in dilute alcohol, when no precipitate Of bitartrate Of potassium occurred.
