poral bone, made it neceflary to put two or three 
circles of wafh-leather dipt in oil around the helix 
of the ear. On working the air-fyringe, the external 
ear fwelled, and became red ; and at length the pa-

air was re-admitted. One of thefe three patients

tion, and received permanent advantage;, the others 
received neither benefit nor difiervice. 
If this fmall degree of fuccefs from the ufe of the 
cupping-glafs, as fo little pain or trouble attends the 
operation, fhould encourage other deaf perfons to 
make ufe of ir, it may be a means to give fome light 
into the intricate difeafes of this organ, the ftrudture 
of the parts of which, and their uies are yet fo little 
un der flood.
