Polyanthus. SeePRiMuoss. POLYPODY, or P0/.IJ podium, L. a genus of plants comprising 142 species : 1 8 of which are indigenous, but the iollowing only deserve to be mentioned: 1. The viilgarc, or Common Polypody, is perennial; grows on old walls, shady place*;, and at the roots of trees : it liowers from June till October. — The root of this plant has a sweetish tastej but, by long boiling, it becomes bitter. Vv'hen frevh, it operates as a mild laxative, so that an infusion of six drams of this root, in half a pint of boihng water, may be taken in di- vided doses. 2. The FiUx-mas. Sec Feux the Male, vol. ii. p. 262. 3. The Oit'iipterls, or Heath Polypody, thrives on most of the dry hills of Scotland j also in moist woods, and mountainous si- tuations of England. Jt flowers from July to October. — This plant is likewise perennial, and its leaves emit a verj- agreeable scent. POMAIUM, an ungoent, which was formerly prepared from >0. X.II. VOL, »?. POM [417 apples, lard, and rose-water, tri- turated together to the consistence of an ointment. At pesent, it is generally copnpoilnded by beating up lard with a certain quantity of rose-water, and communicating to the mixture the odours of violets, roses, jessamines, &c. Pomatums are commonly used in dressing the hair 3 and as many are deprived of that ornament, chiefly by dissipation, mercenary- adventurers amuse the public with various preparations, which are sold to the credulous with the speciou.9 pretence of rendering the hair long and thick. Such mixtures, how- ever, consisting frequently of hurt- ful ingredients, we refer the reader to the directions already given, in vol. ii. p. 423. — ^Thcse unguents are also occasionally employed for icaiififying the face and skin; re- movirig pimples, and other cutane- ous eruptions ; especially by those votaries of fashion and vanit}', who are addided to tlie use of ardent spirits, whether pure or mixed ; and who endeavour to conceal the effects of such indulgence, by re- laxing the s! in with unftaous ap- plications. Here we cannot too' severely reprimand parents, and more particularly mothers, thus pitiably situated ; because the rao- ment."ry gratification of the palate, or a temporary exhilaration, ap- pears to suppress every moral rc- lleftion, every duty they owe to themselves and their children ; while they eventually render them- selves vietims of disease and misery.
