110 A RING. 59 



by the exhibition of iodine internally : the hydriodate of 

 potash, given in doses of 5j or 5ij once or twice a day, at the 

 time we are employing the ointment. If this does not suc- 

 ceed, mercurialising the system seems to present itself as a 

 resource ; though I, for my own part, have little to say in 

 favour of it. In regard to such treatment as this, however, 

 although it holds out a prospect of success, in a case wherein 

 the roaring is but recent and manifestly traceable to late 

 inflammatory aff*ection — which may be still 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 has, from its duration, become 

 established, and where all remnant of increased 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 tra- 

 cheotomy on a roarer, had the good luck to cut against one of 

 these bands, and so, like a prudent man, excised it, and 

 thus par aventure achieved a cure on the horse whom 

 he had anticipated but to relieve. The circumstance was 

 eagerly caught at as opening a new and successful field to 

 experimenters, and the windpipes of many roarers were most 

 mercilessly slit open in search of similar bands. Alas ! so 

 many disappointments followed, however, that the new ope- 

 ration 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-up the windpipe. In fine, this is an operation 

 which, considering the extreme rarity of such cases, no 

 man is justified in performing unless he can practise auscul- 

 tation to that perfection that he can positively say, bands 

 of lymph do exist, and point out precisely the spot of their 

 existence. 



Treatment of roaring from tight reining-in. — One 

 cannot rationally entertain hopes of cases of even this kind, 

 of auy considerable duration. In time, as we have seen,
