GENIT 0-URINARY IRRITATION. - In all kinds of irritation of the genito urinary tract it is useful. Irritable blad der, priapism, chordee, seminal emis sions, incontinence of urine, and sexual erethism in its varied phases yield to lupulin, given in doses of 5 to 10 grains in syrup or jelly (larger doses of lupulin may cause colic and constipation).
MACE.—Mace (Macis, S. P.) is the arillode of the seed of Ilfyristica fragrans (nutmeg), which is indigenous to the East Indies. Its active principle is a volatile oil, which closely resembles oil of nutmeg. Mace and its volatile oil are used principally for flavoring purposes, but occasionally as carminatives. Mace is given in doses from 1/2 to 1 grain. The oil (non-official) may be given in doses of 1 to 3 drops on sugar.
Physiological Action. — The volatile oil, as shown by the experiments of H. C. Wood and Cadeac and Meunier, causes, when injected into the veins of lower animals, marked intoxication, character ized by tremors, loss of co-ordination, and gradually-increasing frequency of respiratory motions. In excessive doses there is narcosis; loss of reflexes and death from paralysis of the respiratory centres follows.
Therapeutics.—Mace is an aromatic stomachic and tonic, and in large doses a powerful narcotic. The oil is sometimes employed externally, as a rubefacient in paralysis and rheumatism. Poisonous doses cause a sensation of great thirst, a feeling of tightness in the chest, and in duce vomiting. Coffee and stimulants are indicated when poisonous doses have been taken.
MAGNESIA.—Magnesium is a metal, light and having the appearance of sil ver, which, when rolled in thin plates or ribbons, can be ignited, and will burn with a brilliant, white flame, giving off a dense white smoke, which is the oxide, or magnesia. The metal is not used in ? r • magm.‘sia. and
