ON ROARING.

ing the cartilages inwards. A bony tumour, growing from the 
cervical vertebras, I have seen, in one instance, occasion incuinblo 
roaring: it formed between the first two veitebice. 
Temporary cases of roaring sometimes occur from simple in¬ 
flammation of the parts, or spasm in the muscles of the larynx, 
and ceases with the restoration of the parts to health. 
Treatment. —In the early stages a cure may often be effected, 
and in the chronic state much relief obtained. 
The first and most obvious treatment that suggests itself, is to 
give the organs their full liberty of action, and gradually to extend 
them by reining the head up two or three hours daily, between 
pillars, "or to the side rings of the stalls, allowing play for the 
head. . . . 
Local bleeding from the jugular or palatine vein is serviceable. 
Pass a seton transversely under the larynx, or one each side be¬ 
hind the angle of the jaw, taking great care the parotid gland, or 
its duct, or the jugular vein, does not become injuied. A veiy 
skilful hand is required to perform this operation, and a proper 
blunt-pointed slide seton needle*. Mild purgatives, occasionally 
moderate exercise, and not too full a diet, are essential. 
In about a month the advantages derived will be evident. 
In desperate chronic cases, tracheotomy has been employed 
with considerable advantage, by cutting down through the skin 
and separating the muscles, and excising about an inch in 
breadth of two of the cartilaginous rings. A small bulbous tube 
may be kept in and tied round the neck a few days, at intei vals, 
to keep Ihe parts extended until the air passes freely without it. 
In about a month the parts will be healed, and the animal be 
much relieved. 
A CASE OF BRONCHITIS. 
Jhj C. Percivall, Esq., Enniskillen Dragoons. 
A BAY gelding, twelve years old, in very high condition (indeed 
far too much so, being overloaded w r ith fat and flesh), was taken 
out of the stable by the groom early in the morning, for the pur¬ 
pose of having his usual exercise, in apparent good health and 
high spirits. lie had not left the stable more than thice-quaitci* 
of an hour, during which time lie had had nothing but walking 
exercise, when he was suddenly seized with great difficulty of 
breathing, sweating profusely; and it was with the utmost difn-
