WHISTLING AND ROARING. 4:00 



ten or fourteen days, when a rest may be given, to be again 

 continued for a similar period. At the same time, and while 

 receiving these medicines, smart blistering applications ought 

 to be employed around the throat and larynx, being brought 

 well forward between the branches of the lower jaw, and well 

 up to the aural region. 



The best blister for this purpose is an ointment composed of 

 equal parts of common cantharides and the bin-iodide of mer- 

 cury ointments. 



Unfortunately the greater number of the cases of roaring 

 or whistling which we encounter in young horses seem to 

 be the result of the laryngeal lesions muscular paralysis and 

 atrophy. They are certainly, also, the most hopeless as respects 

 treatment. 



It is probable that such measures as smart blistering, or the 

 application of the actual cautery, may in some instances be 

 productive of good by arresting atrophic changes, and impart- 

 ing strength to the weakened tissues. It is said by some that 

 when employed early a fair percentage of recoveries may be 

 expected ; while from the fact that benefit has resulted in 

 even a moderate number of instances, they are always worth 

 a trial. 



It has been proposed, by operative interference, to remove 

 the offending cartilage, which through muscular paralysis has 

 dropped into a false position. The removal of this, it was 

 thought, might give increased calibre to the air-tube, and 

 thus avoid the harsh and unnatural sound. The cases in which 

 this operation have been carried out have not in this country 

 been so successful as to warrant its general recommendation. 

 It is probable that with many, a steady and judicious em- 

 ployment of a galvanic current might be productive of good. 

 From the limited experience which I have had of this and 

 the operative interference, there seems more likelihood of per- 

 manent benefit resulting from the former than the latter. 



Very confirmed and severe cases are much benefited, and the 

 animal often rendered capable of moderate work, by the use of 

 a compress or pad fitted to the nostrils so as to regulate the 

 amount of air admitted to the larynx, and also by the use of 

 a tube inserted into the upper portion of the trachea through 

 which ordinary respiration may be carried out.
