    13D water it is nearly insoluble ; it lias a bitter taste, which is slowly developed on account of its slight solubility ; on the addition ot an acid it becomes intensely bitter. It suffers no change by ex- posure to the air. It is very soluble in alcohol, especially when hot and on cooling crystals are deposited. It restores the colour of litmus which has been reddened, and combines with acids to form neutral and crystallizable salts. When strongly heated it is totally decomposed, yielding ammonia.

Mucilago Seminis Cydonii Mali, P.L. 1788. Decoctum Cydonice, P.L. 1809, P.L. 1824. Take of Quince [Seeds] two drachms, Distilled Water a pint; Boil over a slow fire for ten minutes; afterwards strain. Medicinal Uses.—Quince seeds contain a large quantity of inodorous and insipid mucilaginous matter, which is readily dis- solved by water. The decoction is viscid and nearly colourless; it has been recommended as an application to erysipelatous sur- faces : it is also employed in aphthous affections and excoriations of the mouth, &c. It very readily suffers decomposition, and on this account should never be kept ready prepared. Incompalibles.—Alcohol, acids, and most metallic solutions.
