TUCKERMAN, architect, D. Hl Schenectady, New York, 25 September, 1831. was graduated at Union in 1853, studied architecture under Richard M. Upjohn, and has practised in New York, giving attention principally to collegiate and ecclesiastical architecture. His work (as illustrated in the Church of the Heavenly Rest, New York; the Church of the Good Shepherd [Colt Memorial]. Hartford; and Memorial Hall, Schenectady) is distinguished by marked freshness and originality of conception, felicity of ornamentation, and delicacy of feeling. He has resided largely abroad, and is known as a musical composer of much merit.--Another son, Eliphalet Nott, clergyman, born in Schenectady, New York, 20 September, 1836, was graduated at Union in 1861, and at Berkeley divinity-school in 1862. He took orders as an Episcopalian clergyman, and was rector of the Church of the Nativity in South Bethlehem, Pennsylvania, from 1862 till 1869. From 1866 till 1871 he was secretary and professor of ethics at Lehigh university, and from 1869 till 1871 he was associate rector of St. Paul's, Troy, New York At Bethlehem Dr. Potter was instrumental in building three churches, and in Troy two chapels. In 1871 he was elected president of Union college, and he was chosen to the same office when the college became a university in 1873. In 1872 he was elected trustee. Resigning from the presidency in 1884, he was chosen bishop of Nebraska, but declined, and accepted instead a prior call to become president of Hobart college. He received the degree of D.D. from Union in 1869.--Alonzo's brother, Horatio, P. E. bishop, born in Beckman, Dutchess County, New York, 9 February, 1802; died in New York city, 2 January, 1887. He was graduated at Union college in 1826, ordained deacon in July, 1827, and became priest the following year. His first charge was at Saco, Maine In 1828 he was elected professor of mathematics and natural philosophy in Washington (now Trinity) college, and took an active part in plans for the enlargement of the college. In 1833 he became rector of St. Peter's church, AI-bany, New York, and held that post till 1854, when he was elected provisional bishop of the diocese of New York, and consecrated in Trinity church on 22 November of that year. On the death of Bishop Onderdonk in 1861, he became bishop of the diocese. The 25th anniversary of his consecration was celebrated on Saturday, 22 November, 1879, by services in Trinity church, and on the following Tuesday by a reception in the Academy of music, at which deputations from the other dioceses in the state of New York were present, and addresses were made by William M. Evarts and John Jay. The bishop's last public service was held, 3 May, 1883, at the end of a long and fatiguing visitation, after which he was prostrated by an attack. . of pneumonia from which he never rallied. He died at his residence, after being confined to his room three years and eight months. When Bishop Potter came to his diocese it was in a state of great depression and disquiet, owing to the controversies that resulted from the trial and suspension of his predecessor. (See ONDERDONK, BENJAMIN T.) His administration resulted in the restoration of order, quietness, and peace, and in great development and prosperity. Among the notable events in his episcopate was the subdivision in 1868, when the dioceses of Long Island and Albany were set off. He was among the chief members of the house of bishops, and took an active part in the Lambeth conferences in September, 1867, and July, 1878. He entered zealously into the measures that had for their object the reunion of the dioceses that had been separated temporarily from each other during the civil war, and was among the prominent figures in the general convention at Philadelphia in 1865, at which the southern bishops, appearing in the persons of two representatives, were received with general and enthusiastic rejoicings, and without conditions or questions, or allusion to the past. Bishop Potter was a man of remarkable good sense and tact, calm, wise, and patient, an able administrator, one whose judgment was rarely if ever at fault, always temperate and conciliatory; and to these qualities were due the good order, peace, and prosperity of his diocese. He was a man of unusual literary culture. Among his personal friends and correspondents outside of his own country were such men as Bishops Wilberforee, Selwyn, Jackson, of London, Hamilton and Moberly, of Salisbury, and Medley, of Fredericton, Stanhope, Archdeacon Sinclair, and the Rt. Hon. Sir J. T. Coleridge. The growth of the diocese of New York under his administration may be inferred from the statistics taken from the convention journals, though they are imperfect. In 1854 the diocese reported 290 clergy, 9,700 confirmations, 4,482 baptisms, 19,730 communicants, and $207,341.35 in contributions, in 1868 there were reported 446 clergy, 3,930 confirmations, 6,314 baptisms, 33,000 communicants, arid , $1,005,138.21 in contributions. Bishop Potter took a lively interest in city mission work among the laboring classes and the poor, and devoted to that subject a great part of his annual addresses to the convention. His publications are limited to pastoral letters, addresses to the clergy and laity of the diocese, and occasional sermons. In person Bishop Potter was tall and of a dignified and noble presence; he belonged to the old high-church school, of which Keble, Pusey, and Isaac Williams were among the best illustrations, yet his sympathies went out freely toward all Christian people. He was buried in the cemetery at Poughkeepsie, where an appropriate monumental stone marks the place of his rest. --Horatio's son, William Bleecker, mining engineer, born in Schenectady, New York, 23 March, 1846, was graduated at Columbia in 1866, and then, entering tile school of mines of that college, received the degree of E.M. in 1869. He continued for two years as assistant in geology at the school, and also served under Dr. John S. Newberry (q. v.) on the geological survey of Ohio. In 1871 he was called to the chair of mining and metallurgy at Washington university, St. Louis, Missouri, which place he has since held. During these years he has built up an extensive professional practice in the line of examining mineral deposits and mining processes, with reports on the same. Professor Potter is a member of scientific societies, and in 1888 he was elected president of the American institute of mining en-grocers. His scientific papers have been confined to proceedings of societies to which he belongs.
