234 THE &OG IN DISEASE. 



Sulphate of zinc, about two to six grains to the ounce, 

 half water and half glycerin, is one of the best. 



When there is much foulness, a little boracic acid or 

 iodoform may be blown up to advantage. 



The external parts must be protected from the irritat- 

 ing discharge or a form of eczema will result. For this 

 purpose the oxide-of-zinc ointment, or one containing a 

 little iodoform, etc., will be useful. 



Attention to the general health is very important, 

 tonics as quinine, iron, phosphates, cod-liver oil, etc. 

 being demanded, and proper evacuations of the bowels, 

 etc., indispensable. 



A dog long affected with catarrh is apt to get into a 

 dejected condition, and his psychic treatment is not the 

 least important. 



Ozsena is the term applied to a form of catarrh with a 

 fetid, more or less bloody and purulent discharge, which 

 tends to irritate all parts with which it comes in contact. 



If it does not yield to the treatment for chronic ca- 

 tarrh, a careful examination of the nasal passages is called 

 for to ascertain whether there is not disease of the bones, 

 etc. The external openings of the nose should be pro- 

 tected with some antiseptic, as iodoform ointment or vase- 

 line. This is also a good application internally, or iodo- 

 form powder, etc., may be blown up the nostrils. 



Catarrh may also be due to parasites.
