106 OZENA. 



by its usually flowing irregularly, being coughed up in great 

 quantities, more decidedly purulent, and the gland or glands sel- 

 dom affected. The discharge from ozena is constant, muco- 

 purulent, and attended by enlargement of the glands. It is of 

 imrhense consequence that w& should be enabled to distinguish 

 the one from the other ; for while ozena may, sometimes at 

 least, be manageable, the other is too frequently the precursor of 

 death. 



The cause of ozena cannot always be discovered. Chronic in- 

 flammation of the membrane may assume another and malignant 

 character. In severe catarrh, the membrane may become 

 abraded, and the abrasions may degenerate into foul and foetid 

 ulcers. It is not an unfrequent consequence of epidemic catarrh. 

 It has been produced by caustic applications to the lining mem- 

 brane of the nose. It has followed hemorrhage, spontaneous, or 

 the consequence of injury. 



In some cases, and those as obstinate as any, it cannot perhaps 

 be traced to any probable cause, and the health of the animal 

 has not appeared to be in the sUghtest degree affected. 



The steam of a bran-mash, scalding hot, could, by means of a 

 nose-bag, be made to penetrate the cavities of the nose, and would 

 cleanse the part. By means of the nose-bag and warm mash, 

 chloride of lime might be introduced into the cavities, removing 

 the stench and arresting the tendency to decomposition. The 

 vapor of turpentine, or of resinous pine shavings, can by the same 

 means be brought in contact with all parts of the membrane, and 

 it has been found serviceable. A run at spring grass promises 

 still better. It is the finest alterative, depurative, and restora- 

 tive in the whole list of remedies ; and if it is acceptable in the 

 form of a salt-marsh, there is no better chance of doing good.* 



* Note hy Mr. Spooner. — When a naaal gleet is attended by much offen 

 Bive smell, we may rest assured that it is not glanders, but that it either 

 arises from external injury, or may be justly included under the designation 

 ozena. This is a rare disease in a horse, and is generally produced by 

 catarrh, particularly that of the epidemic kind. The discharge is usually 

 thick, considerable, and very offensive. The treatment should consist of 

 tonics, internally and externally, fumigations of chlorine gas by means of 

 Read's inhaler, or with the common nose bag ; or, if this does not succeed 

 a solution of the chloride of lime may be syringed up the nostrils every day, 

 or may be alternated with a weak solution of the sulphates of zmc and cop- 

 per, and applied in the same manner. Nasal gleet, attended with fcetid 

 smell, and proceeding from one nostril only, is usually produced by some 

 blow, or external injury. This much resembles glanders, and has often been 

 confounded with It.
