gone. I at once extracted the broken tooth and another, and the jaw was put in place with the greatest ease, and we allowed her to slowly come to. She made a perfect recovery. In my experience of thirty-five years this case is unique, I am glad to say.
I do not suggest that these cases present any specially interesting features, but as they are a little out of the run of our daily work I venture to think they may interest you. I have always considered that as dentists, or rather surgeon dentists, we ought to study the surgery of the mouth more than we do. The high manipulative skill that a dental surgeon must acquire, gives him great advantages over the general surgeon in some operations about the mouth, and should be more turned to account than it is. I do not wish in any way to reflect upon the medical man in the last case, who dislocated the jaw in an attempt to extract a tooth. Such an accident might occur to any one, if the patient possessed a shallow glenoid cavity and lax ligaments. Such contretemps are fortunately rare however.
Mr. WOODRUFF said the cases referred to were of great interest, especially the last with reference to the luxation of the jaw. It had happened to all who had had any considerable practice that occasionally, without undue force, the lower jaw did slip out. He had had one or two cases where it had happened previously, and he had used his best endeavours to prevent its recurrence but it had still happened. There was no blame to be attached. It was simply due to the fossa being so small and the lower jaw not being properly locked in. They must be rather generous, therefore, in their condemnation of other men who did this sort of thing. It struck him that Mr. Hunt was hard on the medical man who did it; seeing that it happened again with his partner it might not have been the doctor's fault.
The HON. SECRETARY asked Mr. Hunt if he knew anything of the pathology of the case of the cavity that he found after ten years.
Mr. HUNT said with regard to Mr. Woodruff's suggestion, it had not been his good fortune or misfortune to have a dislocation during extraction, except in one case of a man, and he had a remarkably loose jaw which dislocated on the slightest provocation. This case, however, occurred in a strong, healthy young woman. If he seemed to reflect on the medical man he did not intend to, because he knew these accidents would occur with the most careful. While there might have been some looseness of the articulation, certain it was that the doctor had made tremendous efforts to get the tooth out, and injured the soft parts extensively. There was an immense Ideal of force used. With regard to Mr. Goard's question he was inclined to think he did not remove the whole of the dead bone. A part was prob. ably left, and in the course of the next ten years it set up a kind of action whereby the dead bone came into a sort of softened solution, the cavity constantly enlarging with the irritation of a foreign body. The size of the cavity was enormous, and it looked impossible to do anything but excise that portion of the jaw, but when he could leave such good healthy walls he was content to.
K. FOSTER LANE, L.D.S.Eng., Honorary Dental Surgeon to the Deal and Walmer Cottage Hospital.
T. W. F. ROWNEY has been appointed by the War Office, Dental Surgeon to His Majesty's troops in Derby and the district.
North Midland Branch.
A MEETING of this Branch was held at Hull, on Saturday, February 22, and was well attended, especially by the members of the East Riding of Yorkshire, and many had come from the west coast of Lancashire. An enjoyable "social" on the Friday evening opened the proceedings, an excellent programme being provided by the members, and Mr. Storey's sons contributed violin and cornet solos.
The Council assembled early on the Saturday morning, and had several meetings during the day to conclude a somewhat lengthy agenda.
Those present were: Messrs. T. Gaddes (President), J. C. Storey, I. Renshaw, T. Mansell, W. H. Gilmour, G. H. Lodge, A. A. Mathews, C. Rippon, J. A. Woods, and David Headridge (Hon. Sec.). Letters regretting inability to attend were read from Messrs. W. E. Harding, E. P. Collett, J. M. Nicol, T. E. King, R. Edwards, C. Stokes, G. O. Whittaker, and W. H. Waite, G. G. Campion, and G. Brunton.
The important subjects considered were the reports of the Committees, that to nominate the Hon. Secretary, Mr. R. M. Capon, as suggested, was unanimously agreed to. And that of the Committee on Standing Orders, with certain amendments, was also adopted, and the committees named therein appointed. The question of a "Stock Exchange" advertisement was held in abeyance, and the legal cases were referred to the Committee on "Law and Ethics."
The Rules of the Leeds and District Sections were considered, and several new members elected.
A report of a Committee regarding advertising by L.D.S.Engs. was presented, also a statement of a case of successful prohibition of a medical practitioner allowing his name to be used in connection with an advertisement. A vote of condolence was passed to the widow of Mr. Arthur Cocker-an old member of the Branch.
Other matters included nomination of officers and arrangements for General Meeting.
The General Meeting commenced at 11.30. Amongst those who signed the attendance book in addition to the members of the Council were: Messrs. P. T. Leigh, H. Mahoney, Alf. Cocker, S. Mitchell, J. A. Fothergill, E. Catt, W. Cass Grayston, W. Storey, G. E. Wilson, J. A. Taylor, J. W. Lumley, A. B. Wolfenden, W. E. Margetson, V. R. Morley, J. L. Charter, J. Hayes Rice, Z. C. Blyth, G. Fisher, J. S. Wallis, R. M. Capon, Frank Harrison, C. Browne-Mason, T. Audas, J. W. H. Wilson, and in addition there were three visitors.
The PRESIDENT, having welcomed the members, said: The Council has carefully considered and thought out a means of extending the usefulness and the influence of the Branch. With these conditions in view the new Rules have been framed. Those Rules were, you will remember, accepted and confirmed by the Branch at the Annual Meeting at Harrogate, and they have also been approved by the Representative Board. Provision is therein made for the formation of District Sections in connection with the Branch. It is hoped that that provision will stimulate and encourage groups of Members to form small societies affiliated with the Branch. The Leeds and District Section, founded in 1897, has proved a great success, and continues to grow in numbers and in
usefulness. Because of the opportunities which it presents for Members frequently meeting together for social, intellectual, and mutual intercourse, the Section has been the means of bringing men into the Association, and also into the Branch, that they might enjoy those facilities and advantages. That our confrères in the Hull district should likewise band themselves together as a section of the North Midland Branch would certainly appear to be to their personal benefit, and for the furtherance of that esprit de corps which is the soul of professional brotherhood. I would heartily commend this suggestion to the earnest consideration of our friends in this eastern area of our Branch.
In order to facilitate the bringing of reputable practitioners into the fold of the Branch and of such a Section, with the minimum of expense to the individual, there exists the Associateship of the Branch with the nominal subscription of five shillings only. Associates of the Branch have not any rights in connection with the General Association; they have two privileges only, viz., entitled to attend the meetings of the Branch, and also to become Associates of a District Section. We regard the Associateship as a first step towards full Membership. It is a provision that has proved useful in different ways and that has brought Members into the Association. Those two factors -the Associateship and District Sections-work for good and for the advancement of professional brotherhood.
The PRESIDENT showed a large piece of a maxilla containing the three molar teeth, fractured during a previous attempt to extract those teeth, and also a model presenting little or no resulting deformity.
Mr. GADDES read a paper.1
Mr. F. HARRISON showed a number of specimens of various dental anomalies and dilated on the occurrence of supernumerary teeth in the upper incisor region. He pointed out that the supernumerary teeth in the lateral incisor region were in character of the lateral incisor form, but as they approached the central incisor region they became first tubercular and then spiky. The CHAIRMAN remarked upon the interesting nature of the paper, and said the conclusions arrived at were worthy of more than ordinary attention.
Mr. J. A. WOOD said the suggestions put forward by Mr. Harrison were quite new. The method suggested, that the further the supernumerary teeth were removed from the lateral region the less they partook of the nature of lateral teeth, was worth thinking about and worth observing. In the course of his remarks Mr. Wood advocated the collection of such cases as mentioned by Mr. Harrison for the purpose of having them placed in a museum.
Mr. HEADRIDGE congratulated Mr. Harrison on the interesting specimens he had brought before the meeting, but doubted the deductions drawn, and explained some of the views held in regard to “supernumeraries." He urged the necessity of duplicates of these sort of cases being sent to the museums associated with the different schools, as from a large collection interesting testimony would be forthcoming.
Mr. HARRISON said he only threw his remarks out as suggestions. There were three forms, viz., supernumerary teeth like the lateral teeth, the tubercular, and last of all the conical shape which come in between and behind the upper central incisors.
Mr. W. C. GRAYSTON read a paper on "Some Forms of Extracting Forceps."

Mr. J. C. STOREY (Hull) showed several models of cases of supernumerary teeth that he had taken at various times in his daily routine of practice, bearing on the casual contributed by Mr. Harrison. He further presented for inspection two cases which he had shown at meetings of the Odontological Society, the first being a case of replantation of a bicuspid which had lasted for eighteen years after he replanted it, and, according to a letter from the patient, had been quite comfortable until a month before it dropped out. The other was one of dilaceration, which had been demonstrated to be this by the aid of Röntgen rays. Specially interesting was the result of the treatment which, as shown from models, was very successful. He also exhibited models of a younger brother of the same patient who singularly had an irregularity in a similar position, which, however, by watching the case and waiting, was proved by a later model to be an irregularity merely and not dilaceration.
The CHAIRMAN characterised Mr. Storey's contribution as a very valuable one to keep in mind. He (the Chairman) stated that the Council had that day decided to form a committee of scientific investigation to collect data bearing upon the science and practice of dentistry. The subject matter mentioned by Mr. Storey was a very fitting one for their attention. It was only by a number of cases that any collection of practical value could be got together; therefore they would perceive the desirability of keeping on record all such cases that came within their ken.
Mr. STOREY read a paper by Mr. Coysh, entitled "A Case of Replantation of Upper Incisors, making use of a New Form of Splint."
Mr. P. T. LEIGH read a paper on "A Few Notes on Bridge Work.” ' Mr. WALLIS related an incident which happened to him on the previous Monday morning, when, on extracting a lower canine tooth it flew out and struck him in the left eye. He also showed a model of a supernumerary in the molar region. On one side it was a distinct molar and on the other it was more of a conical shape. He further exhibited two bone substances, supposed to be teeth, that were taken out of a mouth, and were the most extraordinary upper centrals he had seen in his practice. Mr. Wallis also showed a case of two centrals of a child aged 12, only represented by very small beads of enamel; the child had been in the habit of taking teething powders when a baby.
Mr. C. RIPPON showed an extraordinary case of an accumulation of tartar. The patient was an invalid who had been in bed for some years and the medical adviser thought it was a tumour. One day, however, in a fit of coughing the tooth and its accumulation of tartar was expelled from her mouth. Mr. Rippon also showed a case where false teeth had been repaired by the village blacksmith.
Mr. J. A. FOTHERGILL showed a model which dealt with the case mentioned by Mr. Harrison. The model showed the whole of the teeth except the left canine and the left central. The case was treated in 1895. A few months ago the case turned up again, and he was surprised to find a supernumerary tooth had come between the central incisors. It was rather difficult to know where the supernumerary was situated when the case first came under his notice. He imagined it was just between the root of the central incisor.
Mr. S. MITCHELL mentioned a case in which by the aid of the Röntgen
rays he was enabled to find the position of certain teeth in the gums.

In the afternoon session, after the discussion on the "Casuals" read in the morning had concluded, Mr. Ernest CATT read a paper on "Capping Pulps." Mr. TURTON read a paper entitled "Impressions of the Mouth.” '
The CHAIRMAN said he must congratulate the Members upon the success of the Hull meeting, and formally thanked the readers of the papers, and the contributors to the Museum.
Reports of Societies and other Meetings.
Odontological Society of Great Britain.
AN ordinary monthly meeting was held on January 27, Mr. W. A. MAGGS, President, in the Chair.
The following gentlemen were elected members of the Society: NonResident—Mr. Edgar Ashby, L.R.C.P., M.R.C.S., L.D.S.Eng., 58, Bootham, York; Mr. M. Philpots, L.D.S.Eng., 29, High Street, Windsor; and Mr. Charles F. Witcomb, L.D.S.Eng., 26, Wellesley Road, Croydon. ResidentMr. F. H. J. Carter-Braine, L.D.S.Glas., 67, Wimpole Street, W.
The CURATOR (Mr. J. F. Colyer) announced the presentation to the Society of a large number of old instruments, bone dentures, &c., by the Students' Society of the Royal Dental Hospital of London.
Mr. ERNEST B. DowSETT exhibited some interesting sections of human teeth, showing Plici-dentine (?) The sections showed an absence of pulp canals, with aberrant formations of dentine throughout the roots, and radiating dentinal tubes. Mr. Dowsett said that he had ventured to bring them forward as anatomical peculiarities and examples of human plici-dentine; they were certainly, he said, object lessons in root reaming.
Dr. E. A. PETERS read a paper on "The Use of Suprarenal in Dental Cases" :-
In dentistry there seemed to be three groups of cases in which suprarenal might be more readily employed. It might be used: (1) As a hæmostatic; (2) as an adjuvant to local anesthesia; (3) as a local application to allay the pain of inflammation.
The use of a liquid extract being for obvious reasons impracticable, he had employed for most cases an extract from Messrs. Burroughs and Wellcome's dried gland; the tabloids are powdered and shaken with cold water, to form 10 or 20 per cent. mixtures, according to the weight of the original fresh gland. The containing vessel is then placed in boiling water and heated, with occasional shaking, for ten minutes. The filtrate is secured and is reliable for two days or so. If allowed to stand, a dark brown precipitate forms and carries with it the efficient properties. The vaso-constricting body is said to be an alkaloid.
Five minims of a per cent. solution of the tabloid extract, diluted with normal saline, injected beneath the skin of the forearm, gives the typical suprarenal reaction. In five to ten minutes the skin on the site of injections becomes white and "goose skin" forms; in marked cases the skin resembles
