So wedded are we to custom, so hampered by precedents, so enslaved by habit, that we cannot bring ourselves to believe that what is wrong in our proceedings can possibly be corrected, or what is right in the practices of our neighbors can possibly be adopted.

The operation pales the face slightly, but the pulse is little, if at all, affected. In profound sleep the breathing is stertorous, but otherwise free. The inspirations are deeper. The mind dreams with much activity, and a few seconds appear as hours, from the number and rapid succession...
Страница 29 - This diminution however, of the sensibility to external impressions, is not unfrequently accompanied with severe degrees of pain." In fact, in making the experiments to which I have above adverted with the pounded ice, few of us could allow the hand...
Страница 15 - ... vapours. So far as my experience goes, it has shown no tendency to cause faintness ; and usually, after its employment, no unpleasant feeling whatever remains. I think it may be found useful as a remedial agent in certain headaches, tetanus, asthma, and other spasmodic diseases, and to prevent pain in such small operations as the extraction of a tooth or the opening of an abscess.
Страница 43 - CHAPTER IV. PREPARATORY TREATMENT OF THE MOUTH. THE condition of the mouth is not sufficiently regarded in the "application of artificial teeth, and to the neglect of this the evil effects that so often result from their use are frequently attributable. An artificial appliance, no matter how correct it may be in its construction and in the mode of its application, cannot be worn with impunity in a diseased mouth. Of this fact, every day's experience furnishes the most abundant proof. Yet...
