About the year 1825 he was invited to read a course of lectures on dentistry before the medical class of the University of Maryland. He also contributed several able papers to medical journals on his physiological researches. Having; ever in mind the elevation of the dental profession, he. Dr. Chapin A. Harris and others sent a petition to the Legislature, in December, 1839, to establish a Dental College, the faculty to consist partly of dental and partly of medical practitioners. The Legislature having granted a liberal charter, Dr. Hayden, at the advanced age of seventy, entered upon the duties of the chair assigned him in that institution. The Baltimore College of Dental Surgery. In 1840, in New York, was held a meeting of the best dentists then in the profession, the outcome of which was the formation of the American Society of Dental Surgeons. This outcome was chiefly due to the labors of Dr. Hayden, and he was unanimously chosen president of the society and re-elected each year until his death. Until the illness which terminated his life Dr. Hayden continued to exercise the duties of his profession and to lecture to his class. He died on the 26th of January, 1844, m the seventy-fifth year of his age. CHARLES McMANUS, D.D.S., Hartford, Conn.

educating men for the duties of the dental profession; accordingly, in the winter of 1839-40, he obtained signatures to a petition to be laid before the Legislature of Maryland for the incorporation of a College of Dental Surgery at Baltimore. After much opposition the charter was granted and Dr. Harris continued through life to exercise the duties of one of its most important professorships. In 1840 Dr. H. H. Hayden went to New York and Boston with the design of forming a Dental Society. Dr. Harris, among others, immediately responded to the call and the speedy result was the organization of the American Society of Dental Surgeons. In 1840 he published a Monograph of the Physical Characteristics of the Teeth; in 1841 a Disserta- tion on the Diseases of the Maxillary Sinus. He also revised his Principles and Practice ' ' through several editions, and completed his Dictionary of Dental Science, Biography, Bibliography and Medical Terminology. He also translated from the French the works of Delabarre. Through his labors for the profession and his unbounded generosity, although his practice was large, he died poor in the city of Baltimore on the 29th of September, i860. Horace f). RaycUn was born at Windsor, Connecticut, October 13, 1768. He was remarkable from his childhood, and it is said that he learned to read almost as soon as he did to talk, and at once contracted that love for books which was so marked all through his life. While a boy he also manifested a great fondness for natural history which clung to him in after life. At ten years of age he began the study of classics, but, probably for want of means, soon abandoned it and at the age of fourteen, in the humble capacity of cabin boy of a fine brig, he made two voyages to the West Indies. At the age of sixteen he became apprenticed to an architect until he became of age. He then pursued his business in the West Indies, Connecticut and Xew York. While in the latter State he had occasion to call on Dr. John Greenwood (dentist) for his services, when the thought struck him that he would like to follow that profession. Obtaining such information as he could from Dr. Greenwood ' s instructions and from his books, he went in 1804 to Baltimore, Md., to practice the profession and labored to elevate the calling. To this end he commenced the study of medicine and in later life the honorary degree of Doctor of Medicine was conferred upon him both by the University of Maryland and the Jefferson Medical College of Philadelphia. In 1814 he was appointed acting surgeon in the Thirty-ninth Regiment of Maryland Militia.

OR! : : ' Vindicatory. den ta l su ERy AYE you ever seen a slate-quarry? If not, you have missed the sight of one of the most wonderful treasures of antiquity. rSvcMil Strange as this statement may appear, you will be convinced of its correctness when you are told that recent discoveries prove beyond a doubt that these slate deposits are no more and no less than remnants of the old schools and colleges founded many thousand years ago. Paper being unknown in those days, the boys and girls cut soft stones into slices and used them for their writing and ciphering. In order that a record might be kept of the progress made by the pupils, these plates were piled up, and we now find stacks of them here and there, which are used over again by the youngsters of our day. Of the overwhelming proofs that these slates have thus actually been used for educational purposes, at least two should be mentioned. In the first place, petrified remnants of lunch, or of wrapping material for lunch, are found imbedded in this slate. The lunch containers seem to have been made from the leaves of ferns or palm trees, while fish appears to have been one of the delicacies relished universally at the midday recess, though snakes and reptiles of various kinds appear among the articles accidentally left behind by the school children and found stored away between the slates. The second proof is that the writing on these slates in many cases is yet well preserved. To the casual observer the signs and figures found resemble such impressions as would be made by the scratching of a hen,
