Prof. A. Graham Bell, now a resident in Salem, occu- 

 pied the evening with a singularly interesting and curi-

 of hay was attached to one of the ossiculte, and a hearing 

 tube was inserted in the outer ear. When any sound 

 w^as uttered into the tube, the membrana tymfpani was set 

 in vibration, and its motion was communicated to the 

 style. This latter was then caused to record its vibration 

 upon a plate of smoked glass passed rapidly underneath.

 tube caused the style to trace a different curve upon the 

 glass. A Uirge number of these tracings were exhibited 

 to the audience by means of the camera.
