There can be no reasonable doubt that much of the good obtainable from the use of narcotics in painful affections is attributable to the benefits arising from increased sleep, during which trophic and irrita- tive disturbances are corrected. This aspect of the question has, up to the present time, received far less attention than it deserves. The best manner of administering morphine, the al- kaloid of opium, which of late years has obtained such a high position among the resources of the pharmaco- poeia, is by the means of the hypodermic syringe. When it is desired to exert a more or less general effect upon the nervous centres, the point at which the injection is made is not so much a matter of consequence as where a more local action is required. Any spot about the abdomen or arm, where the skin is at once thin and ]cose, and where there are few veins, will do. It is usually well to begin with a dose of from one- sixth to one quarter of a grain, and increase the same as required. When the effective dose has been ascer- tained, it may usually be employed for a considerable period without material increase. By degrees, how- ever, the system becomes habituated to the remedy, so that in the course of time it becomes imperatively necessary to increase the dose in order to obtain the requisite physiological effects.
