DAY, Henry, lawyer, born in South Hadley, Massachusetts, 25 December 1820. He was graduated at Yale in 1845. He took charge of the classical academy at Fairfield, Connecticut, until 1847, studied in the Harvard Law School, was admitted to the bar in the autumn of 1848, and settled in New York City. He was a member of the Presbyterian (old school) general assembly that convened in St. Louis in 1867, and of the assembly that met in Albany in 1868. He strongly advocated the union of the old and new schools, and was one of the committee that visited the new school assembly, then in session in Harrisburg, and laid before it the views of the old school assembly on the subject of union. He afterward drafted the articles for the basis of union, which were ratified in 1869 at Pittsburgh by the joint meeting of the two assemblies. He became a director in the Princeton theological seminary in 1865, and a trustee and director in the Union theological seminary in 1870. He has published "The Lawyer Abroad, or Observations on the Social and Political Condition of Various Countries" (New York, 1874); and " >From the Pyrenees to the Pillars of Hercules " (1883).
