EXPERIMENTAL PHONETICS. 



of the air in the no.se, the movements of the lips, and the vibrations of 

 the hirynx were simultaneously reeorded. Speeial contrivances were 

 devised for transmitting- these movements to three of Marey's tam- 

 bours, so arrang-ed as to record on the surface of a ))lackened drum 

 three superposed curves which indicated the order of succession, dura- 

 tion, and intensity of the movements of the organs. The emission of 



air from the nostril indicated movements of the soft palat«\ and these 

 were signaled by an india-rul)ber tul)e inti'oduced into one nostril, 

 Avhilc the other end was coimccted with a taml)()ur, ;is in tig. I. A 

 small electi'omagnetic apparatus was place(l over the larynx, and by 

 making and bn^aking a cui'rent the vibrations of the larynx were 

 ti-ansmitted to another tambour. The movements of the lips were
