This is the name of a symptom rather than a disease. It im- 

 plies a sound made in breathing in connection with some contrac- 

 tion of the air passages. The term is however usually reserved 

 for those conditions in which the sound results, from chronic dis- 

 ease or malformation, the noise attendant on laryngitis and other 

 acute diseases being rarely spoken of as roaritig. In neither case 

 does the noise indicate more than that there is some impediment 

 to the ingress and egress of air through larynx or trachea. 



The pitch of the note varies exceedingly with the causes that 

 prodtice it and with the hurried nature of the breathing. There 

 have thus arisen the epithets of grunter, roarer, whistler, high- 

 bloiver, piper, trumpeter, ivheezer, etc. The most common dis- 

 tinctions are those of roaring and whistling. The r^(a;r<?r produces 

 a loud deep basso .sound in in,spiration, the larynx or windpipe 

 being only slightly narrowed while the whistler or piper produces 

 a shrill blowing or sibilant noise because of the greater constric- 

 tion of the passage. The term grunter is derived from the facts 

 that a roarer usually makes a grunting noise when struck or 

 threatened with a cane, and that when the tipper cartilages of the
