are turned up where they can be conveniently so 

 done ; in other positions strips of gold must be 

 soldered on and the margin let in flush with the 

 surface of the teeth, which now may be fixed on 

 and completed. 



It appears to me that in this way every requi- 

 site is obtainable — a good fit, smooth and round 

 edges, and work of great strength and durability 

 combined with lightness. The work can, more- 

 over, be readily taken to pieces for repair; and, 

 from what I have seen and read, combines all the 

 advantages of either of the new methods, except 

 that of economy in money, time, and sldll, 



I would also draw attention to the swivels 

 which I have for some time made and used, as 

 having advantages over those in common use. 



Mr. Putnam, of New York, read the following paper — 



On the Vulcanite Base as applied to Dentistry, its 

 history and progress to the present time. 



Mr. President and Gentlemen, — In appearing 

 before you to-night to read this paper, in com- 

 pliance with the expressed wish of several of your 

 members (and by the permission of your Council), 

 I feel considerable difficulty, coming among you, 

 as I do, a comparative stranger, and proposing 

 a system of artificial dentistry, which, in a mea- 

 sure, is opposed to your preconceived ideas in this 

 branch of our profession.
