£60 GALVANISM IN DEAFNESS. 



a story among the inhabitants of the Feroe isles, if they be- 

 lieved that the diver lived constantly on the dry land. It seems 

 obviously to have originated among them from a similar 

 cause that produced it among the inhabitants of the Orkney 

 and Shetland islands, a peaple till lately connected with 

 those of the Feroe isles by Frequent intercourse and common 

 language. 



Jalous t . 0ryf *" ^ he trut]l is ' l bL ' llev . e > tlmt the two species of colymbi 

 here noticed live almost constantly on the water ; when they 

 leave it, it is only for the purpose of incubation; and they 

 then seem, from the best accounts, always to choose some se- 

 questered spot very near to their favourite element. Indeed 

 the position of the legs of all the divers, and the structure 

 of their feet, show that they are totally unfit to live con- 

 They neTer stantly, or even principally on the dry land. 1 have never 

 I'idlv Imh se€I1 e ither the c. immer or c. glacialis attempt to fly; nor 

 stay very long did I ever hear any one say, that they had observed them do 

 under water. gQ ^ \\rjien closely pursued they swim with great ease and 

 rapidity, and dive for a much longer time than any other 

 bird I recollect to have observed.

Inquiry concerning the Use of Galvanism in Deafness. By 

 a Correspondent, 



-I 



To Mr. NICHOLSON. 

 SIR, 



Apphca.ion of J^T appears, that galvanism is successfully applied 111 some 

 galvanism in f ., , .. . .... , , 



cases of deaf- cases ot deafness; and particularly in such as cannot be re- 

 news, lieved by other means. I am so fully persuaded of your 

 desire to render the Philosophical Journal subservient to 

 objects of utility, that I presume to request you to invite 

 your correspondents, to transmit a particular account of the 

 mode of applying galvanism in cases of deafness. 

 I am, Sir, 



Your most obedient servant,
