TREATMENT OF UOAHING. 
Whenever the ball produces purging, omit it for a few days, and 
then give it again every day, or every other day, according to 
circumstances. Apply a strong blister to the throat; and likewise 
—should there appear any reason to suppose disease exists in the 
windpipe—extend it along the front of the neck, in the course of 
the pipe. As soon as one blister is worked off, apply another; or 
else insert setons through the parts. The latter is an excellent prac¬ 
tice where we are desirous of keeping up continual irritation. 
In regard to all this treatment, however, let it be observed, that, 
although it holds out a prospect of success in a case wherein the 
roaring is but recent and manifestly traceable to some inflammatory 
affection which is still probably concealed under the form of an 
occasional cough, a shortness or pursiness of breath, or some slight 
fever in the system lurking about the air-passages, it will not and 
cannot prove of any avail in a case in which the roaring is, from 
its duration, become established, and where all remnant of inflam¬ 
matory action has, for some time past, disappeared. 
Excision of the Cross-bands of coagulable Lymph.— 
It is said—for its truth I cannot vouch—that, once upon a time, a 
veterinarian in performing the operation of bronchotomy on a roarer 
had the good luck to cut against one of these bands, and so, like a 
prudent man, excised it, and thus fortuitously achieved a cure on 
the horse whom he had anticipated but to relieve. The circum¬ 
stance was eagerly caught at as opening a new and successful field 
to experimenters, and the windpipes of roarers were most merci¬ 
lessly slit open in search of similar bands. So many disappoint¬ 
ments followed, however, that the novel operation was abandoned 
for the introduction of a practice which, if it does not offer the 
same glittering prospects, is, at all events, free from evils that may 
accrue from cutting and slitting the windpipe. In fine, this is an 
operation which, considering the extreme rarity of the cases wherein 
it is applicable, no man is justified in performing, unless he can 
practise auscultation in that perfection, that he can positively say, 
bands of lymph do exist, and precisely point out the place of their 
existence. 
Treatment of Roaring from tight reining-in. —One can¬ 
not rationally entertain hopes of cases of even this kind, of any con¬ 
siderable duration. In time, as w'e have seen, not only does the 
distortion of the larynx and windpipe become permanent and irre¬ 
mediable in consequence of the parts losing all their wonted tone 
and elasticity, but changes of their structure take place : the muscles 
shrink and waste away; and the cartilage itself becomes altered— 
probably converted partially into bone. Should the subject be a 
harness-horse, and have been in the habit of being tightly borne up, 
let him, for the time to come, be driven without any bearing-rein 
at all; and, in addition to this, when in the stable, let him be bitted
