246 OZENA. 



food. The animal should be daily exercised (weather permit- 

 ting). If the appetite fails, discontinue all medicine for a 

 time ; otherwise bad consequences may ensue. 



One evil, amongst others, to be guarded against in Ozena 

 (and indeed in the generality of diseases), is that of over 

 treatment. Practitioners may trephine into the frontal sinuses, 

 or into the malar cavities, or inject fluids into the nostrils ; 

 until, in the end, the patient becomes ten times worse than at 

 the commencement of the treatment. "When this occurs (and 

 it happens more frequently than is suspected) cease for a time 

 all treatment except that of washing the nose with tepid water, 

 and keeping the patient clean ; or if the weather be favour- 

 able, turn the animal to grass, and allow him a run of two or 

 three months ; when, in all probability, he may come up per- 

 fectly free from the disease. 



Some practitioners recommend Blisters and Setons to the 

 bridge of the nostrils. I have not found them of any value. 



In conclusion, I may remark, that I consider TrephiniDg of 

 the malar cavities of little or no use beyond evacuating any 

 matter which they may contain. 



LAEYNGITIS. 



(inflammation of the laetnx.) 



Laryngitis is a disease which but rarely exists unconnected 

 with other maladies of the respiratory organs, being generally 

 accompanied either with Epizootic Catarrh, or Bronchitis ; 

 nevertheless it occasionally presents itself with such force and 

 clearness, as to show that it can, with strict propriety, be 

 classed as a primary disease. 



Not unfrequently Laryngitis constitutes the principal feature 

 in Epizootic Catarrh.
