DAVIS 290 DAVIS and printing done. Mr. Squire was engaged to superintend the drawings, maps, and edit the observations made by Davis, the latter con- tinuing his practice in Chillicothe. In 1848 the result of his extensive explorations ap- peared in a work entitled "Ancient Monuments of the Mississippi Valley," which formed the first volume of the "Smithsonian Contributions to Knowledge." While editing this work Mr. Squire prepared and read before the Ethnological So- ciety a paper embodying the principal facts of the new book, and it was published with their proceedings. This caused great dissatisfaction, and Prof. Henry came near throwing up the whole thing. He also, unbeknown to Squire or Davis, placed his own name before that of Dr. Davis on the title page. Dr. Davis paid Mr. Squire's board during the time of printing the work. Mr. Sqiiire received fifty copies, the same number as Dr. Davis. Dr. Davis bore the entire expense of these investigations, viz., the traveling, surveying, and opening of over two hundred mounds, amounting without any allowance for time to nearly $20,000. All the remuneration he ever received for all his time, labor and expenditure was fifty copies of the book, given him by the Smithsonian In- stitution, and the $10,000 received for his col- lection, purchased by Mr. Blackmore, of Eng- land, who built a museum for its reception and dedicated it to his native town, Salisbury, where it now remains. Unfortunately for Davis, he placed his fifty copies in a bookstore for sale, and soon afterwards a fire in the store destroyed them. So far as the "Ancient Monuments" are concerned, the above facts show who was the originator and ruling spirit !n the getting up of this great work. Davis contributed to the medical journals, and in 1850 prepared a "Report on the Statistics of Calculous Diseases in Ohio." In 1841 he ope- rated successfully on a man thirty-five years old for strabismus, and always claimed that his was the first one of the kind in Ohio. Davis came to New York in 1849. In 1850 he was elected professor of materia medica in the New York Medical College and lectured there for ten years. Failing health compelled him to retire from practice and the chief cause of his death. May 15, 1888, was debility from old age. He left four children, two sons and two daughters. His remains were taken to Chillicothe, Ohio, and placed by the side of his wife. Med. Reg., State of New York, Albany, 1888. Davis, Gwilym George. (1857-1918). Gwilym G.

Henry Gassett Davis, pioneer orthopedic sur- geon, was born in Trenton, Maine, November 4, 1807. He was a descendant of Dolor Davis, a Cape Cod man ; graduated at the Yale Medi- cal School in 1839, practised in Worcester and Milbury, Mass., until 1855, when he went to New York. Dr. Davis was a good observer and clinician and had a keen and original mind. He early became interested in the study and treatment of fractures and deformities, and forcibly ad- vocated the use of continuous "elastic trac- tion" for the relief of joint irritation and the correction of deformity. He applied traction by means of adhesive plaster with the weight and pulley, and other mechanical devices, and
