HUNTERS 



there are other causes, such as morbid growths 

 in connection with, or in juxtaposition to, the 

 larynx; a growth or growths in the nasal 

 passage; stricture of the air tube; malformation 

 of the larynx ; lead poisoning ; and the consump- 

 tion of Indian vetch (Lathyrus sativus). When 

 roaring is of an intermittent nature, the chances 

 are that it is due to some morbid growth, of a 

 pedunculated stalked character, in the vicinity of 

 the larynx, which by its presence, temporarily oc- 

 cludes the laryngeal opening. Its displacement 

 and replacement, in the situation named, have 

 positively been proved to be concurrent with the 

 development of the roaring sound at irregular 

 intervals. What may be termed acute 7varing 

 sounds are those incidental to swelling around 

 the throat, so commonly observed in strangles: 

 to the consumption of the Indian vetch ; to 

 inflammation of the larynx, and to other factors 

 of a less definable nature. As previously stated, 

 the sound varies in its intensity : some hunters 

 make a tremendous noise with the slightest 

 exertion, whereas in other instances, it is not 

 only necessary to employ severe, but also pro- 

 longed exertion in order to bring the sound to
