NASAL GLEET. 201 



Supposing it to liave grown, and the surgeon is endeavouring to extract 

 it, lie must not use any great force. It must not be torn out by the root ; 

 the tumour must be gently brought dowTi, and a ligature passed round the 

 pedicle, as high up as it can conveniently be placed. If the polypus can 

 then be returned to the nose, the animal will suifer very little incon- 

 venience ; and in a few days it will slough off, and the pedicle will contract, 

 and gradually disappear. 



If the polypus is so large that it cannot be well returned after it has 

 been brought down, we must, notwithstanding, use the ligature, passing it 

 round the pedicle sufficiently tightly to cut off the supply of blood to the 

 tamour. We may then immediately excise it. Except the pedicle is ex- 

 ceedingly thick, there will be little or no hcemorrhage. Should some 

 bleeding occui% it will probably soon stop, or may be stopped by the 

 cautery, which should, however, be avoided if possible, for our object is 

 to produce as little irritation as may be in the membrane, and the actual 

 cautery will be apphed with considerable difficulty in the cavity of the nose, ■ 



In very bad cases, when the tumour cannot be drawn out of the nose, it 

 may be necessary to slit up the ala or side of the nostril. It -will be better, 

 however, not to cut through the false nostril, for that consists of a duplica- 

 ture of such thin integument, that the stitches can hardly be retained in it, 

 when the horse will be continually snorting at the least inconvenience. It 

 will also be difficult to bring the edges of this thin membrane accurately 

 together again, or, if this be effected, there is scarcely life enough in it for 

 the parts readily to unite. The false nostril should be avoided, and the 

 incision made along the lateral edge of the nasal bone, beginning at its apex 

 or point. The flap will then conveniently tui^n do\vn, so as to expose the 

 cavity beneath ; and there will be sufficient muscular substance to secure 

 an almost certain union by the first intention. The nostril being opened, 

 the pedicle v^dll probably be displayed, and a ligature may be passed round 

 it, as already recommended ; or if it is not actually in sight, it may 

 probably gradually be brought within reach. 



NASAL GLEET, OR DISCHARGE FROM THE NOSE. 



There is a constant secretion of fluid to lubricate and moisten the mem- 

 brane that lines the cavity of the nose, and which, under catarrh or cold, 

 is increased in quantity, and altered in appearance and consistence. Tliis 

 will properly belong to the account of catarrh oi- cold ; but that which is 

 immediately under consideration is a continued and oftentimes profuse 

 discharge of thickened mucus, when every symptom of catarrh and fever 

 has passed away. If the horse is at grass, the discharge is almost as green 

 as the food on which he lives ; — or if he is stabled, it is white, or sti-aw- 

 coloured, or brown, or even bloody, and sometimes piu^ulent. It is either 

 constantly running, or snorted out in masses many times a day ; teasing 

 the horse, and becoming a perfect nuisance in the stable, and to the rider. 

 This has been known to continue several months, and eventually to destroy 

 the horse. 



The discharge is sometimes confined to one nostril, and there may exist 

 considerable tumefaction of the submaxillary glands, which has caused 

 this disease to be mistaken for glanders. Should any doubt exist, no time 

 should be lost in obtaining the opinion of a veterinary surgeon respecting 

 its nature. 



If the discharge is not offensive to the smell, nor mixed with punalent 

 matter, it is probably merely an increased and somewhat vitiated secretion 

 from the cavities of the nose ; and all fever having disappeared, will fre- 

 quently yield to small doses of blue vitriol, given tvsdce in the day. K
