My object in presenting this subject before the Society to-night is manifold; I wish to show that in general practice the indications are limited for the use of opiates. We must fully realize that Ave have a broader basis for medical science than symptomatology, in order to give our patient the full benefit of our knowledge. Our position being at all times one of trust, Ave must endeavor, in helping our patient, to find the cause and remove it, rather than hide the symptoms it gives rise to by an opiate. Aside from the possible mental disturbances such a course of treatment might induce, it often materially complicates surgical efforts to relieve patients, the results of Avhich Ave have repeatedly heard discussed at these meetings.
In order to discuss this drug Avith due fairness, it will be necessary to give a few moments to the consideration of its physiological action
