WHEN SUPPURATING, ETC. 379 



to like it, so greatly is it the fashion in the present 

 day to exalt bitter beverages. 



The effect of the solution upon the decalcified 

 dentine of the tooth is to form a sort of leather, 

 I believe, a true tannate of gelatine or analogous 

 substance; and in cases where the pulp has not 

 been actually exposed, although pain may have 

 been experienced in the tooth, a covering is formed, 

 under which calcification of the pulp seems to take 

 place very readily. 



In cases where the pulp has been completely 

 disorganized and has suppurated away, the solu- 

 tion is still valuable in subduing the discharge. 

 I will give a good case to illustrate this. 



Mr. D — , ast. 19, called upon me on 13th March, 

 1860, to have a right, lower, wisdom tooth re- 

 moved, on account of the pain he believed he had 

 suffered in it. On examining his mouth, I found 

 the wisdom tooth decayed to the level of the 

 surrounding gum, which was quite healthy, while

 molar of the same side, which was decayed on its

I'he ether and tannin was applied twice, and
