VETERINARY DENTAL SURGERY. 67 



The cutting of the upper sixth molar frequently 

 causes slight catarrhal disorders. There will be a 

 thin, clear, watery discharge from one or both nos- 

 trils, usually the latter, which will continue as long 

 as the irritation exists. 



It is at this age that " wolf teeth are so destructive 

 to the eyes" It is a well known fact that small 

 supernumerary teeth (wolf teeth so called), exist in 

 most animals at this age unless previously extracted. 

 Their presence however, has nothing to do with 

 disease of the eyes. The discharge from the eyes is 

 due to the eruption of the last molar, and usually 

 subsides when that tooth is once through the gums. 



Opthalmia, both periodic (moon blindness) and 

 simple may result from teething ; but in such cases 

 we would suspect an hereditary tendency or pre- 

 disposition to those diseases, which only want a 

 sufficient stimulus to cause them to break out, when 

 they will make their appearance. 



The removal of supernumerary teeth (wolf 

 teeth), lancing the gums or withdrawing any teeth, 

 acts as a counter irritant, and may possibly be followed 

 by the remission of some of the opthalmic symptoms. 

 An incision or a blister below the eye often will pro- 

 duce the same result, so also will bleeding from the 

 angular vein. Wolf teeth can never be looked upon 

 as the source of serious disease of the eyes. If 

 their removal is desired, it should be accomplished
