 SIR, 



A HE inclofed communication on the efFeds produced in a Introduftory 

 cafe of deafnefs by the perforation of the tympanum of the ^"'®*^' 

 ear, is extrafled from a letter which I have juft received from 

 Mr. Maunoir, an eminent furgeon at Geneva. The hiftory of 

 this cafe, drawn up by fuch an intelligent and accurate ob- 

 ferver, appears to me curious, both from the phyiiological re- 

 marks which it contains, and from the llriking illuftration 

 which it affords of a new mode of pradice lately propofed in 

 tliis country. And, as this fubjed feems fully as interefting 

 in its philofophical point of view, as in its connexion with 

 practical furgery, I (hould with, if you think it proper, that 

 you would give it a place in the next number of your valuable 

 Journal. I have the honour to be. Sir, 



Your obedient humble fervant,

 in this cafe, the euftachian tubes were obliterated. In con- ^^ * 

 denfing the air in his mouth and noftrils, he was totally unable 

 to diftend the membrane of the tympanum, a thing which is 

 yery eafy to do for any one who enjoys a perfed fenfe of hear- 

 ing. He could fcarcely hear, even when you (houted in his 

 ears, and although fo long deaf, he had not acquired the fa- 

 culty of under ftanding by the motion of the lips. After pe- 

 rufing the paper which I lately publilhed in the Biblioth^que 

 Britannique, Mr. F. conceived that he might be oneof thofe 

 in whom the hearing could be recovered by the perforation of
