Dental review; devoted to the advancement of dentistry. . ORIGINAL COMMUNICATIONS. 1113 The roots of the teeth to be shown were each imbedded in plas-ter and mailed to the various members with the request that they befilled according to the usual method pursued in like cases, and re-turned to the committee, with a brief description of the response was quite general. The teeth were then removed fromthe plaster, a number attached corresponding to the number of writ-ten description, then the roots were carefully filed down to exposethe root canal throughout the entire length. They were then photo-graphed and lantern slides made which I shall now have the pleasureof showing you. Slide i, No. 43. Root—lower bicuspid. Dried writh alcohol andhot air. Introduced chloropercha on broaches of different openings with warm blunt instrument. Result: Sectionshows division of canal in lower third forming island, and numerousforamina, at least four. Filling perfect at apex, some shrinkage in. larger portion of canal. No. 16. Root—a long curved with alcohol and warm air. Introduced sandarach varnish onsmooth broach.

As canal increases in size crownwardsome air spaces are noticeable. No. 24. Root—Lower with alcohol and hot air. Introduced eucalyptol, excess after-ward taken up with cotton-wound broach. Gutta percha point in-serted with pliers and after somewhat softened by the oil, was fur-ther softened by heat and packed with broach small enough to pass,say, half way to apex. Result: Apical third neither cleansed orfilled, remaining two-thirds shows considerable room to let. Slide 2, No. 66. Bicuspid root.
