In testing the hearing power, a cylinder watch couldbe heard only when laid upon the auricle, or whenpressed upon the temple. Speech could be understoodonly at a distance of three feet. Upon opening theEustachian tubes by my method, the thin depressed cica-trix bulged out; the hearing distance for the watch,however, had not increased, whilst for sj)eech the im-provement amounted to one foot. In the right membrana tympani, in front of, and below,the manubrium, we found a perforation as large as a pin-. Supplement. 177 head, out of which, upon the Valsalvian experiment,came a drop of thick pus, soon followed by several air-bubbles. When the pus had been removed from themeatus, the watch was heard at a distance of two inches,speech at five feet, and the ticking of the watch could beperceived when laid upon the temple. The tuning-forkplaced upon the vertex was more distinctly heard in theleft ear, because, the impediment to the conduction ofsound out of this ear being greater, the vibrations trans-mitted through the cranial bones were retained and moreclearly perceived. We had, therefore, in this case to dealwith a purulent catarrh of the middle ear, upon the rightside, associated with perforation of the membranatympani. The same process was also present, at an earlier period,in the left ear, though there had been no suppurationfrom the mucous mem
