duty, but with due regard for his opinion, I think it would be an imposition and should be performed by a special Committee.

UNDESIRABLE ATTENDANCE.

The doors of our Association will always stand open and a hearty welcome will always await all reputable and decent practitioners of either medicine or dentistry. To all such we gladly extend an earnest right hand of fellowship and bid them come, mingle with us and be cne of us, and in what I am about to say I hope I may be rightly understood. It is becoming noticeable each year that a certain class of objectionable characters who are ineligible for membership on account of the degrading commercial manner in which they conduct. practice, have the brazen effrontery to infest our meetings with their presence. On clinic days they are especially numerous, and their brass noses may be seen in front of every clinician, while others may see as best they can. There is nothing in common between that class and the members of this Association or our eligible invited guests. They are opposed to codes of ethics, to societies, to professionalism and to all high and noble sentiments. They have never contributed a dollar, a sentiment or a thought to the advancement of dentistry or to any other progressive science. Their every act, word and thought has been to retard advancement, pull down and degrade. Then why are we in any way bound by liberality, sociality or otherwise to allow such arch enemies of our profession to infest our meetings with their obnoxious presence? It is true we must maintain at any inconvenience, the spirit of liberality, nothing selfish, nothing secret, but are we to allow this audacious imposition by such scabs and blots simply because they have the cheek and the determination to push themselves into respectable company uninvited, and after obtaining all the benefits procurable, the next day in public prints and by private conversation in public places, proclaim to the people, "that associations are their worst enemies, are trusts and combines whose only object is to keep up high prices and commit robbery." Under the existing circumstances it would seem that we have the right and should exercise the privilege of ridding ourselves of such intruders even though it became necessary to point out to them an opening in the wall through which they might retire.

THANKFULNESS.

We must not forget to return thanks to a kind Providence that our number has not been decreased since last we assembled, by any dreaded visitation from the scythe of time and extend a hope that it may meet His approval that the same manifold blessings may extend through another year.

PROGRESS AND FUTURE.

Looking back at the unexampled progress made in the last few years, I wish to say generally, and from which we may derive satisfaction as well as consolation, that we who have lived and labored in this time and age have, upon the whole, not ill performed our duty. But while it is our privilege to take consolation from this thought, lct us be careful that we do not become too well satisfied with ourselves and our surroundings. We must push onward in the future as in the past, there must be no retrogression. Let us continue to work in the fields of science and having obtained knowledge, let no unworthy prejudices or selfishness induce us to withhold from any part of our professional brethren that which is justly their due. As you have received, freely give of the knowledge which you are fortunate enough to have in your possession. “A man is a man only as he makes life and nature happier for others." Therefore, let us never cease to delve in nature's laboratories, in search of truth that we may be better fitted to help others who may be in need of assistance, ever remembering that it is "more blessed to give than to receive," and "to wear out than to rust out." In our work at this meeting let no differences or contentions arise to retard progress unless perhaps it be "that noble contention or rather emulation as to who can best work and best agree." Let no previous convictions or prejudices against any system or any man, prevent you from examining into every subject brought before you, with impartial eyes and an unbiased mind, that the light of truth and knowledge, which is power, may find free ingress into your higher being which may be instrumental in guiding you in your future investigations.

With these convictions sunk deep into your minds, I feel persuaded that you will push forward with increased zeal and that the result of the deliberations of the next few days will mark an epoch in the

history of our profession and a new mile stone will be set up on the road of progress.

I now heartily invite you to allow your minds to freely partake of the many wholesome fruits which the labors of our efficient Committeemen have gathered together for your benefit.

On motion of Dr. Foster, the following Committee was appointed to make subsequent report on the President's Address: Drs. A. R. Melindy, Chmn., Geo. S. Vann, and J. Hall Moore.

The Committee on Chemistry, Metallurgy and Anatomy being called Dr. J. P. Gray, Chmn., made the following report:

Dr. Gray:—I am sorry that I have no formal report to make. I wrote to the President that possibly I would have a paper on Anatomy as applied to Prosthesis, but did not want it to go in the program. He has placed it in the program, and I have no paper. I am sorry that this Society was imposed upon by being promised a paper under this head and then not have one. Dr. Chace was to have prepared a paper on Chemistry, but the President asked him to write one on Operative Dentistry, as they were scarce on that subject, so the President is to blame for you not having any paper from this Committee. Doubtless, I would have had one, had the President not put it in the program.

Possibly the Committee will have some report to make before the session closes.

Committee on Operative Dentistry was called, and Dr. J. J. Sarrazin, New Orleans, Chmn., reported several papers to be read, and also a good many excerpts from the Dental Journals, which being very long, and having several papers from this Committee, he suggested that they be read by title, and motion was carried to this effect. The excerpts are as follows:

Excerpts from Articles in Operative Dentistry and collateral subjects prepared from some of the 1901 Dental Journals and presented by some members of the Committee on Operative Dentistry of the S. B. N. D. A.:

Excerpts from the Dental Review and from the International Dental Journal are from the pen of Dr. J. E. Chace of Ocala, Florida, as follows:

The Dental Review for Jan., reports a paper by J. Milton Walls, D. M. D., on "Enamel Cleavage Relative to Preparation of Cavities," in which an important point is brought out on the preparation of gingival enamel margins. The principle laid down is that the enamel bevel should be great, in proportion to the extension of the margin rootwards. The reason for this is clearly seen on a study of the Micro-photographic pictures of the enamel prisms in situ, with which this article is illustrated, the angle made by the prisms with dentine increasing as the root is approached.

Dr. A. W. Harlan is reported in the Dental Review for Jan. as announcing before the Chicago Dental Society the success awarded his experiments with Papain as a pulp digester. He recommends one grain of papain, one drop pure glycerol and one drop of 1-300 Hel. to form a paste, which is applied to a dead pulp and sealed with cement. He advises washing cavity with acidulated water after the devitalizing application is removed, then sealing in the paste, allowing the same to remain two or three weeks, when the pulp may be removed as a jelly-like mass.

The Dental Review for Feb. publishes a paper read before the Minn. State Dental Society by H. L. Cruttenden in which he presents a new appliance in the way of a cement syringe to be used for filling roots with cement or chloro percha and for cementing crowns. and bridges. It is claimed that with this instrument root canals may be filled without leaving air bubbles.

The Dental Review for June publishes a paper by Elliott R. Carpenter on the Extract of the Suprarenal Capsule and its Dental Use. In this preparation we have a new drug which promises to be of great use as a haemostatic, one that will stop bleeding and do it quickly. When used in combination with powdered crystal Hydrochlorate of cocaine it produces a deeper seated anaesthesia than cocaine alone and one of longer duration. The author prefers to apply the cocaine first then the Suprarenal extract in powdered form. This is used in adjusting cervical clamps, in excising interdental fungoid, in pyorrhea pockets, etc., etc. The application not only acts nicely as an anaesthetic, but makes the operation almost bloodless.

The Dental Review for July publishes "The Treatment of Difficult Approximal Cavities," which was read before the American

Dental Society of Europe by Wm. A. Spring of Dresden. In those cases where the cervical margin of cavity extends too far rootwards to allow the adjustment of the dam, the author, after preparation of cavity, etc., touches the gum with trichloracetic acid to prevent weeping, applies matrix and fills cervical third of cavity with tin-gold I to 6. The matrix is then removed, the dam applied and the filling finished with cohesive foil.

In the May number of the International Dental Journal is published "An Attempt to Explain the Sensitiveness of Dentin," by Alfred Gysi of Zurich. The author starts with four fundamental propositions viz.: 1st, No nerve fibers have been found in the dentin. 2nd, Dentinal Canals are filled with a watery organic substance. 3rd, At the inner border of the dentin exists a rich net work of nerve fibers. 4th, Water is practically an incompressible substance. From these data this writer argues that the pain felt on excavating a cavity is due to the pressure produced by the bur or excavator which is transmitted without diminution by the contents of the tubuli to the nerves below the odontoblastic layer of the pulp.

The pain from the application of salt, sugar, etc., is supposed, under this theory, to be due to the reverse of this, or a pull due to the affinity of these substances for the watery contents of tubuli.

This author believes it impractical to undertake to relieve the hypersensitiveness of dentin at one sitting, and advocates sealing in the medicament for 24 hours, thereby giving the agent time to act.

In a paper on "Some New Appliances," read by H. F. Hamilton before the American Academy of Dental Science, and published in the International Dental Journal for June, the author submitted to the Academy a suction device for the relief of pressure in a forming abcess and for drawing the pus from a blind abscess. The appliance is used in connection with the saliva ejector or a bicycle pump in which the valves have been reversed. It consists of a tip made of a metal tube, one end of which is of a size to slip into the ejector tubing, and the other end small, so as to allow its entrance into a cavity of decay. A concave disk is soldered about 1/4 inch from the small end, and in using this is filled with softened gutta percha and pushed into the cavity; the gutta percha shutting off communications with the outside, the power of the ejector is brought to bear on the interior of the canals.
