A practical treatise on the diseases of the ear including the anatomy of the organ . e cleanly and delicate one. After air has been forced into the middle ear in this man-ner, the membrana tympani should again be examined by thesurgeon, to determine if it has become injected, or if it hasundergone any change in position; that is to say, he shouldsee whether the current has actually reached the cavity of thetympanum or not. Most authorities recommend the use of an instrument likethe stethoscope, which is placed in the ear of the patientwhile the air is being driven through the tube, and they claimto be generally able to decide as to whether the air enters bythe sound communicated through the tube. I am constrainedto think that it is very difficult to distinguish sounds proceed-ing from the pharyngeal mouth of the tube from those pro-duced in the cavity of the tympanum, and I do not, therefore,attach that importance to the use of the stethoscope in thismanner, that has been usually ascribed to it; but I rely moreupon the appearances of the membrane of the tympanum after. the air has been forced in, with some attention also to thesensations of the patient, as to where the air is felt, than uponthe use of the so-called otoscope—although I would be very 98 DIAGNOSTIC TUBE. far from wholly rejecting its employment, or from denyingits value. The otoscope consists essentially of a piece of elastictubing with a tip on each end, designed for the ear of thepatient and that of the examiner respectively. It should notbe called an otoscope, but rather, as Kramer suggests, thediagnostic tube. The mirror for examining the ear should becalled the otoscope, just as that for examining the fundus ofthe eye is named the ophthalmoscope; that for the throat, thelaryngoscope, and so on. POLITZERS METHOD OP INFLATING THE EAE. The next means of examining the condition of the Eusta-chian tube and cavity of the tympanum is named, from thegentleman who suggested it, Politzers method.
