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

 ting). If the appetite fails, discontiaue aU mediciae for a time ;, 

 otherwise bad consequences may ensue. 



One evU, 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 favourable, 

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

 months ; when, in aU. probabihty, he may come up perfectly free 

 from the disease. 



Some practitioners recommend Blisters and Setons to the 

 bridge of the nostrils. During my experience I cannot affirm 

 that I have found them of any value. 



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

 the malar cavities of little or no use beyond evacuating any 

 matter which they may contain. 



LARYNGITIS. 



(inflammation 01' THE LARYNX.) 



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 fea- 

 ture in Epizootic Catarrh.
