NASAL GLZET.

the decomposed matter. The Schneiderian membrane may be 

 excoriated, presenting patches of abrasions resembling ulcers, 

 but not the characteristic pit like depression of the glanderous 

 ulcer. The mucous membrance is pale, perhaps thickened and 

 infiltrated, or is of a coppery hue ; and the eye of the affected 

 side appears sunken, gummy at the lids, with a slight discharge 

 of mucus from its inner canthus. 



In every case of this kind the practitioner should be very 

 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 foT 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 honphatics are induced by any 

 unhealthy ichorous discharge. 



Great improvement often resvdta from the effect^ of a shtirp 



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



'tonics being discriminately administered, and the tiest of food 



allowed. Injections of cold water or some slight astringent 



Iwash, as the tincture of the tercldoride of iron, ir^ the proportion 



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



daily, are often very beneficial. Inhalations of sulphiireoiis acid 



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



follows : — 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 membmne, and if sufficiently dilute, does not iiiitate. 



A chronic nasal discharge, with a snoring and snuflling sound 



[during breathing, may arise from some cause of obstruction 



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



membrane, — causing constriction of the anterior nares. These 



sources of obstruction and irritation being remoYcd, the, dis-- 



charge and abuoi-mal sounds disappear.
