[For Formula; for Hypodermic Solutions, see Appendix,] Parenchymatous Injection is the delivery of a medicine deeply into the tissues, either to affect a muscle itself or to locally influence some important nerve-trunk. 1 he principal agents used in this manner are Strychnine for palsied muscles. Chloroform tor sciatic and other neuralgias. Salts of Cocaine for local anaesthesia, and Carbolic Acid lor deep-seated inflammations. The Integument is an active absorbent of crystalloidal substances when its epidermis or cuticle is removed, and many substances may be made to pass through the latter and produce their characteristic effects on the system. By this route there are four methods of introducing medica- ments into the circulation, viz. :—the Endermic, Enepidermic and Epi- dermic Methods and Inoculation. The Endermic Method obviates the difficulty of absorption through the cuticle by removing the latter with a blister, and then powdering the medicament over the surface of the denuded derma. Before the intro- duction of the hypodermic method this procedure was quite common, but it is rarely employed now, as it is both painful and unpopular. An ordinary Cantharides-plaster, followed by a poultice to raise the blister, may be employed ; but a quicker method is to place upon the skin a piece of lint soaked in Stronger Water of Ammonia, covering it with a watch-glass or a piece of oiled silk to prevent evaporation. The blister raises rapidly and should be removed with scissors, and the medicine in powder then placed on the raw surface. Morphine, Atropine, Quinine and Strychnine, are the agents generally used in this manner. The Enepidermic Method consists in placing the medicine in simple contact with the epidermis, no friction being used to hasten its penetra- tion. Chloroform and oleic acid solutions of the alkaloids pass by osmo- sis in this manner with comparative ease, but aqueous solutions act very slowly, and alcoholic ones with great difficulty if at all. Drugs are readily absorbed from the surface of hot, moist poultices, a fact to be remem- bered in directing such applications for children, as narcotic poisoning may follow the liberal use of opium in this manner.
