46 DISEASES OF THE AIR-PASSAGES. 



walking by the side of the other up a hill^ I suddenly heard 

 a whistling behind me, occasioning me instantly to spring 

 round with alarm, thinking there was a roaring or rather a 

 whistling horse galloping close at my heels. My fright 

 subsided, but surprise and curiosity took its place, at finding 

 it was my young friend who was making all this noise in 

 his eflPorts in climbing the hill. On laughing and telling 

 him he was ^' a regular whistler," he informed me, he had, 

 not long before, been the subject of a severe bronchitis, which 

 had left this unpleasant impediment in his breath. 



Pathology of roaring.— This includes the investigation 

 of the morbid and other phenomena on which the existence 

 of roaring depends : it is a part of our subject replete with 

 interest, seeing that it is upon this knowledge that all our 

 hopes and expectations of remedy must be erected. Unless 

 we can arrive at a thorough insight into the cause of the 

 evil we shall deceive both ourselves and our employers in 

 attempts to remove it. To hear people talk about the seat 

 and the cause of roaring, one would suppose that both might 

 be included between the finger and thumb, and that it was 

 either too mysterious ever to be developed, or was universally 

 in one place. Such unscientific and narrow views as these 

 it is that have led people to talk about the cure of roaring, 

 as if some remedy were in existence at once to remove the 

 evil. Such discourse may impose upon our employers ; but, 

 surely, among ourselves, if we aspire to be thought men of 

 science, it must be nonsense in the extreme. Unless what 

 I am going to relate be untrue, it must be evident enough, 

 even to unprofessional minds, that the causes of roaring are 

 many and various, and that, consequently, the remedies 

 cannot but be something like proportionate in number, and 

 oftentimes extremely dissimilar. 



E-OARING IS NOT A DISEASE, BUT A CONSEQUENCE OF 



DISEASE — of catarrh, strangles, influenza, laryngitis, bron- 

 chitis : to which Hurtrel d^Arboval has added, pleurisy and 

 peripneumonia; when, I may remark, bronchitis is, as it 

 generally is, a concomitant of those diseases. Now, let it be 

 observed, that these are all inflammatory diseases of the mu-
