pluggers, the wonderfully delicate nerve extractors, the rubber dam and its adjustments, the saliva pump, the electric mallet, the improvement in our chairs, and that greatest of all boons, both to patient and operator, the Morrison engine, the name of the inventor of which valuable instrument, ought to be indelibly inscribed in letters of gold in the Archives of Dentistry, to say nothing of the application of vulcanite and celluloid, and the many ingenious appliances for the workshop. Surely these should lead us to value the benefits we enjoy, and teach us to strive to use them to the best of our ability, not influenced by the thought of self-glorification in attempting to surpass all others, in the performance of this or that brilliant operation, but ever remembering that the ultimate aim of all our efforts should be the increased amount of good which we are thereby enabled to accomplish for the benefit of our suffering fellow-creatures. Although the _Transactions_ of the Odontological Society contain a very voluminous and valuable collection of papers bearing on one speciality, there still remain numerous subjects and modes of operating which may be made productive of profitable discussion. Such are the replantation of teeth now attracting so much attention, the erosion of the surfaces of the teeth of which so little is known in the present day. The various improvements in the materials for filling, and amongst a variety of subjects, far too numerous to be mentioned here, the startling announcement of the so-called New Departure Creed. As this last is a subject which I think we all feel greatly interested in, and also bears on the branch of Dentistry which we are now considering, I will venture a few remarks on some of the articles of the accepted and new departure creeds as tabulated in the _Dental Cosmos_.
