 inflammation subsided. We were then able to dress 

 the wound, but it healed slowly, taking three months 

 to recover. The jaw was left somewhat thickened. 

 We applied blisters to this several times, and now it

I regard this as one of the most instructive cases 

 that has ever come to my notice. It shows that there 

 may be ulceration of a root of a tooth without any 

 sensible manifestation of disease in the mouth, such 

 as the shrinking of the gum away from the tooth, as 

 we have heretofore been taught is always the case." 



"A case very similar to the above occurred in one
