Third—organization takes place better when the tooth is moderately tightly fitted in solid bone, and for this reason the cicatrix of bone formed after the extraction of a tooth is the most favorable place for implanting teeth. Fourth—that the resorbtion and rebuilding of the tissues of the body necessitate the absorbtion of the dentine of the roots of implanted teeth, and thereby their loss. But that as a temporary replacement of lost teeth, the operation of implantation is justifiable to those who comprehend it to be such. _Discussion_—DR. BUTLER:—I have not performed this operation, as I was doubtful of its final success. The question now is whether it is justified by its duration of three to five years, and the patient's liability to disease, etc. DR. SAGE:—I wish to know what was considered large or small ivory peg. DR. FLETCHER:—The experiments of the men go to show that bone will become organized when ivory will not. The only part of a tooth that may be organized is the cementum. The line of reorganization or absorbtion is a softened tissue, so when the process reaches the crown and is about complete, the crown drops off. If a very fresh tooth is implanted, the membrane may be accepted. The following officers were elected for the ensuing year: President, E. G. Betty, Cincinnati, O.; First Vice-President, J. R.

SMITH:—Mr. President, the essayist this evening has presented a paper which is a resume of the methods of practice of many practitioners throughout the country, but although they have given their methods of capping exposed pulps, I do not see that they give their results, and he cites but one case and pronounces that a failure.
