13. _In the Dysentery of Natives, and in that especially of Native Children_, Dr. Evers (_Indian Medical Gazette_, Feb. 1, 1875) speaks very highly of Acorus given in decoction as follows: Take of the bruised root-stock two ounces, Coriander seed one drachm, Black Pepper half a drachm, Water one pint; boil down to about twelve ounces (or for about a quarter of an hour), and set aside to cool. The dose for an adult is a wine-glassful three times daily; for a child from one to three tea-spoonfuls, sweetened with sugar, two or three times a day. Astringents or Quinine (the latter when the disease is apparently of malarious origin) may be added if necessary. Dr. Evers found this decoction not only useful in _Dysentery and Diarrhœa_, but also in the _Bronchitic Affections of Children_. He considers it worthy of a more extended trial. 14. This root, especially when freshly collected, and retaining its full aroma, is reported, on good authority, to _drive away fleas and other insects_, a fact well to bear in mind in a sick room, as well as elsewhere. 15. +Aloes.+ The inspissated juice of Aloe Socotrina, _Linn._, and other species of Aloes. Musabbar, Ilvá, Yalvá (_Hind._), Musanbar (_Duk._), Móshabbar (_Beng._), Elwá (_Punj._), Mússbar, Sibar (_Kash._), Kariya-pólam, Irakta-pólam (_Tam._), Múshámbaram (_Tel._), Chenna-náyakam (_Mal._), Musam-bara-bóla (_Mah._), Yéliyo (_Guz._), Kalu-bólam, Kari-bolam (_Cing._), Mo (_Burm._), Jadam (_Malay_). 16. Aloes, as met with in the bazaars, are generally imported, and of a very inferior description, but they may be rendered fit for medical use by the following process: Take of bazaar Aloes, in small fragments, one pound; boiling water, one gallon; stir them well together until they are thoroughly mixed, and set aside for twelve hours; then pour off the clear liquor, strain the remainder, mix the liquors, and place in open vessels in the sun, or over a gentle fire, till it is evaporated to dryness. Aloes of very good quality may also be prepared from two indigenous species of Aloe, A. Indica, _Royle_, and A. litoralis, _König_; the former inhabiting dry sandy plains in the Northwestern Provinces, and the latter similar localities on the sea-coasts of the Madras peninsula. The viscid juice with which the thick leaves abound should be collected and evaporated to dryness by exposure in open pans in the sun or over a gentle fire. 17. The principal use of Aloes is as a purgative, in doses of from three to six grains. If administered alone, it is apt to cause griping, nausea, &c.; hence, it is generally given in combination with aromatics, &c. _It is ill adapted for children, for persons subject to Piles, or for Pregnant Females._
