Obituary (The New York Times):
"Edward Hartsinck Day, Professor of Natural Sciences at the Normal College, died last Friday [January 4, 1895] at Algiers [New York], where he had gone on a leave of absence to regain his health. Professor Day, who was a younger brother of Sir John Day, one of the three Chief Justices of England, was born at Bath, England, in 1833. His education was obtained at the Roman Catholic College of Downside and the London School of Mines. During his early years his interest in geology led to his becoming associated with Profs. Huxley, Owens, Hawkins and Ethridge in the Geological Society's work, in which he aided materially in mapping out the geological formations in England's southern counties. He made the first geological survey for the proposed English Channel tunnel under the direction of Sir John Hawkshaw. Prof. Day came to New York in 1866, as assayer to a Montana mining company, and later accepted the post of Assay Master in the Columbia College School of Mines. At the death of Prof. Redfield in 1872, he was elected to the Chair of Natural Science in the Normal College, and held it at the time of his death. Owing to heart failure and pulmonary troubles he was obliged to abandon his work about two years ago. His remains will be interred at Bath, England. He was twice married. His second wife was with him at the time of his death."
