from the natural color of the tooth. There are no doubt other cir- 

 cumstances which influence the color of the decayed part, but just 

 what they are is not easy to determine. 



Tumors may make their appearance on the gums or exostoses on 

 the roots as a result of decayed teeth. A diseased condition of the 

 alveolar process is occasionally produced by dead or carious teeth ; 

 also in extensive caries of the jaw bone. Inflammation of the mu- 

 cous membrane of the mouth (sometimes giving rise to the condition 

 termed lampas), is an exceedingly common result of diseased teeth. 

 This inflammation may become very extensive, involving the whole 

 membrane of the mouth, extending to the throat, where it causes an 

 irritable condition, giving rise to a more or less troublesome cough. 

 Just how far this inflammation may extend is difficult to say, for the 

 mucous membranes of the mouth, nasal chambers, sinuses, pharynx, 

 larynx, esophagus, and bronchial tubes are continuous, without any 

 definite line of demarcation. It does not seem probable that a num- 

 ber of diseased teeth, involving in their disease (especially in young 

 animals), all the ramifications of the facial nerves and the whole 

 mucous membrane of the mouth, could remain for any considerable 

 period without producing grave results. Indigestion in the chronic 

 and even acute form is frequently associated with carious teeth, and 

 is due to imperfect mastication of the food. A very offensive odor 

 is also emitted from the mouth, especially if the carious condition 

 is far advanced T. D. Hinebauch. 



I always trephine if there is a fetid discharge from the nostrils, 

 due to carious teeth producing ulceration of the sinuses, even if I 

 first extract the diseased teeth with the forceps. C. E. Say re. 



THE temporary dentition of the foal, unlike that of children, pro- 

 duces no serious results. The temporary teeth are cut and de- 

 veloped without any apparent change in the animal system, the 

 foal growing and thriving during the process. T. D. Hinebauch. 



FILLING HORSES' TEETH. 



DR. SAYRE says: I think that in cases where caries has not gone 

 too far, that many teeth may be reclaimed and do the animal years 

 of good service. Filling the teeth of horses is only practicable when 

 caries first begins, as the nerve is so large that I think it impossible 

 to destroy it and remove it successfully ; and if it is not well done, 

 it is better not done at all. It is the only treatment we have re-
