Mr. MAHONIE (Sheffield), moved a vote of thanks to the President for his able and eloquent address, and in doing so, said that when the Association was weak, Mr. Campion had come to their aid in a very courteous manner, and they were now asked to give him their heartiest thanks for the paper which they had just heard read. The paper was one which would last more than a year. It was very instructive, and he (Mr. Mahonie) thought that Mr. Campion was eminently capable of giving them instructions in the way of Dental Reform. He moved “That the best thanks of this meeting be given to the President of the Midland Counties Branch of the British Dental Association, for the able and eloquent paper which he had just read.” Mr. W. H. Nicol (Leeds), seconded the motion in suitable terms. Dr. W. H. Waite in supporting the motion, said that it was a very great privilege for them to have such a President as they had in Mr. Campion. His wisdom had been of great service in superintending the efforts which the Executive have had to put forth. They had been delighted that morning with the interesting and instructive address which Mr. Campion had given them, but most of all with the very high and generous tone that breathed throughout the whole of the address, and he (Dr. Waite) thought Mr. Campion had struck a key-note which, when the address came to be printed, would vibrate not only throughout the Midland Counties of England, but through every country where the Dental profession was carried on. The motion was carried with much enthusiasm, and the meeting then adjourned till the afternoon. * * * * * The Members assembled in the Memorial Hall at 2.30 p.m., Mr. Campion in the chair. The PRESIDENT stated that some idea had been started of bringing specimens to the meeting, and in order to show what curiosities might be casually collected, he offered a few specimens to the notice of the Members. Mr. ROFF KING, Shrewsbury, then read a paper on “Modelling and Modelling Composition.” Mr. J. S. CRAPPER (Hanley) read a paper, entitled “New Ideas in Mechanical Dentistry,” and exhibited specimens of teeth which had been manufactured by a new process and sent to him to exhibit. The SECRETARY read a paper received from Mr. F. Richardson, Derby—“Has Vaccination any Effect on the Degeneration of the Teeth?” Mr. H. MARSH (Manchester) read a paper on the “Use of Nitrous Oxide Gas.” Mr. MURPHY desired to ask the Chairman whether Licentiates in Dental Surgery were legally responsible if a patient expired whilst under the influence of the nitrous oxide gas, or subsequently to the administration. In the discussion which followed, there appeared to be a unanimous opinion amongst those present that Licentiates were not responsible, but that it would be impossible to define such a position.
