NASAL GLEET. 527 



mucous membrane is pale, perhaps thickened and infiltrated, or 

 is of a coppery hue; and the eye of the affected side appeal's 

 sunken, gummy at the lids, with a slight discharge of mucus 

 from its inner canthus. 



In every case of this kind the practitioner should he veiy 

 guarded in his diagnosis, as the disease may be glanders in its 

 latent form. Let the animal be isolated, kept in a loose box; all 

 pails, brushes, combs, sponges, &c. made use of for cleaning and 

 feeding him must be kept apart until time develops the true 

 nature of the malady. 



Inoculation with the discharge is unsatisfactory, as inflam- 

 mation and suppuration of the lymphatics are induced by any 

 unhealthy ichorous discharge. 



Great improvement often results from the effects of a sharp 

 fly blister to the face, over the sinuses and nasal chambers, 

 tonics being discriminately administered, and the best of food 

 allowed. Injections of cold water or some slight astringent 

 wash, as the tincture of the terchloride of iron, in the proportion 

 of an ounce to the quart of water, or of sulphate of copper, 

 daily, are often very beneficial. Inhalations of sulphureous acid 

 gas, largely diluted with air, are useful. The gas is made as 

 foUows : — Burn half-an-ounce of prepared sulphur — the milk of 

 sulphur in preference, being a pure preparation — in a moderate 

 sized loose box or stable, and make the animal inhale it for 

 half-an-hour every day. It has a stimulating and tonic effect on 

 the mucous membrane, and if sufficiently dilute, does not irritate. 



A chronic nasal discharge, with a snoring and snuffling sound 

 during breathing, may arise from some cause of obstruction 

 in the nostrils — polypi, or a thickening of the Schneiderian 

 membrane, — causing constriction of the anterior nares. These 

 sources of obstruction and irritation being removed, the dis- 

 charge and abnormal sounds disappear.
