16 THE PRACTICE OF A^ETERINARY MEDICINE. 



yields a dull, dead sound, instead of the resonant sound 

 emitted on percussion of the parts when healthy. Slight 

 enlargement of the affected sinuses may be observed. A 

 large accumulation of pus will give rise to labou^^ed respira- 

 tion. The pus is exceedingly offensive in odour where the 

 osseous structures are involved. Nasal gleet is not a con- 

 tagious disease. 



Treatment. — Isolation as a precautionary measure should 

 be adopted ; endeavour to find and remove the cause. The 

 patient should be kept in well-ventilated quarters, and the 

 diet should be of a highly nutritive character, and sup- 

 plied in liberal quantities. The animal should be allowed 

 to rest, or, at the most, do only light work. The bowels 

 and kidneys are to be kept in as nearly a normal condition 

 as possible, and good grooming is a matter of some import- 

 ance. The nostrils should be kept clean by sponging. The 

 medicinal agents indicated are those which tend to restrain 

 undue activity of the mucous membranes, and at the same 

 time exert a general tonic and alterative action. Ferri 

 sulphate is often productive of good results, as are the 

 following : potassium iodide, cupri sulphate, cantharides 

 pulv. ; the latter being given in doses of grs. v. — x. Fre- 

 quent changes of medicines should be made ; a combination 

 of iodine and iron, forming ferri iodidi, is probably the 

 best agent known in the treatment of nasal gleet, to be 

 given in doses of 5i. — 5ii. twice a day ; ferri sulph. 5i. — 5ii., 

 acid arsen., grs. ii. — v. twice a day, is another prescription 

 highly thought of. Strychnia or nux vomica maybe sub- 

 stituted for the arsenious acid in the usual doses. In some 

 cases counter-irritation (as a blister applied over the part) 

 is attended with marked benefit ; the nasal chambers may 

 be injected with a weak solution of carbolic acid. There 

 is also a very good instrument known as an insufflator now 

 in use, by which the parts may be dusted with various
