Dr. Adams made a vei-bal communication on a modified form ' 

 of telephone which he had constructed for the use of that class of 

 deaf persons in whom the auditory nerve is yet in good condition. 

 The action of the instrument is based on an experiment made by 

 himself, that, if the diaphram of the ordinary telephone is removed, 

 and the magnet core be put in contact with the mastoid process 

 of the temporal bone, the message can be distinctly heard when 

 the ear is closed. A deaf person who cannot hear in the ordi- 

 nary manner, can also hear in the same way if the auditoiy nerve 

 is in sound condition. The same result follows if the diaphram 

 of the telephone is put in contact with the temporal bone.
