PHOTOGRAPHY OF THE LARYNX.

bands are increased instead of decreased in length, and the chink 

 of the glottis is increased instead of decreased in size. In the 

 larynx before examined the chink of the glottis increased in size 

 and the vocal bands increased in length as the voice ascended in 

 each register, attaining their greatest length at the highest note of 

 the middle register ; but in this the vocal bands attained their 

 greatest length at the highest note in the voice of this subject, 

 which corresponds to about the highest note of the middle regis- 

 ter." 



Figs. 227 and 228 are from photographs of the larynx of the 

 contralto singer referred to on page 397, showing the same 

 mechanism of the vocal bands in passing from the lower to the 

 middle register, from E to F sharp, as is shown in Fig. 223, but 

 on a different occasion.

In concluding his Berlin address, Prof. French says : 



" Though the number of series of photographs which have been 

 taken of the larynx in singing is quite large, I do not yet feel 

 justified in drawing definite conclusions from them regarding 

 many of the movements of the glottis at different points in the 

 scale, but from the study made thus far the following conclusions 

 regarding the glottis of the female may, I think, be safely drawn : 



" 1. The larynx may act in a variety of ways in the production 

 of the same tones or registers in different individuals. 



" 2. The rule which, however, has many exceptions is that 

 the vocal bands are short and wide and the ligamentous and car- 

 tilaginous portions of the glottis are open in the production of the 

 lower tones ; that, as the voice ascends the scale, the vocal bands 

 increase in length and decrease in width, the aperture between the
