John Ordronaux, M.D., LL. D., professor of medical jurisprudence in Dartmouth Medical College, died at his home at Glen Head, Long Island, on the morning of January 20, of apoplexy, after a very brief illness. Doctor Ordronaux was born in New York City, Aug. 3, 1829. After graduation he studied law, graduating in 1852 from Harvard Law School, and practiced this profession for a few years in Taunton, Mass., and New York, City. Turning then to medicine, he graduated in 1859 from the National Medical College of Washington, and practiced for many years in his native city. Much of his time was given to professional teaching and lecturing. In the National Medical College he successively filled the chairs of hygiene, medical jurisprudence, pathology, and physiology; in the Columbian Law School, Washington, he also lectured on medical jurisprudence. The latter subject he also taught in Columbia College, the University of Vermont, and Boston University, and had held the same chair in our own medical school since 1864. He was a national authority on this subject, and had written and published much on this and kindred topics. From 1872 to 1882 he was commissioner in lunacy for the state, of New York. He left an estate of 1300,000, about one-half of which is bequeathed to charitable and religions objects. Dartmouth College is remembered to the amount of $30,000, and St. Thomas Church of Hanover and the Mary Hitchcock Hospital are also beneficiaries. Doctor Ordronaux never married, and his nearest surviving relatives are a sister and two nieces. The funeral services were held in the Episcopal church in Roslvn, of which the Doctor had long been senior warden,and at the grave the ritual of the Loyal League was read.
