On Friday, March 9th, occurred the death of two of the six surviving founders of the American Association for the Advancement of Science--Dr. Charles E. West, of Brooklyn, and Professor Oliver Payson Hubbard, of Manhattan. Both were distinguished teachers. Dr. West was born in Washington, Mass., in 1809, and after being graduated from Union College, began his career as a teacher in the Albany Female Academy. He was afterward principal of the Rutgers Female Institute, the Buffalo Female Seminary, and the Brooklyn Heights Seminary, where he remained twenty-nine years. He also assisted in preparing the original courses of instruction of Vassar Female College. He was one of the founders of the Long Island Historical Society; was a fellow of the Royal Antiquarian Society of Denmark; and was a member of the American Ethnological, the American Philosophical, and the New York and the Long Island Historical Societies. Professor Hubbard was born at Pomfret, Conn., in 1809, was graduated from Yale College in 1828, and was appointed Professor of Chemistry, Pharmacy, and Mineralogy at Dartmouth College in 1836. He remained there, with an interval, from 1866 till 1871, in which he devoted himself to lecturing, till 1883, when he became professor emeritus. He was made in 1871 overseer of the Thayer School of Engineering at Dartmouth, and he was a member of the New Hampshire Legislature in 1863 and 1864. Only four of the founders of the American Association are now living--namely, Dr. Martin H. Boye, of Cooperstown, Pa.; Prof. Walcott Gibbs, of Harvard; Dr. Samuel L. Abbot; and Epes Dixwell. * * * * * The firm of Burroughs, Wellcome & Co., says the Lancet, are to be congratulated on the generous care which they have taken to promote the material and intellectual welfare of their employees. Their principal works are at Dartford, where they employ more than eight hundred persons of both sexes, including some two hundred scientific workers. For the purpose of establishing a sort of club for these employees, Mr. Wellcome succeeded in purchasing the Manor House known as Acacia Hall, and the extensive and beautiful grounds in which it is situated. The Manor House he has fitted up as a club for the members of his staff. An old mill which stands close by has been converted into what is called the library building. The upper floor is fitted out as a lecture-room, and there is a library which already contains some thousands of volumes. A third building, called the Tower House, contains club accommodations for men. Then there are elaborate bathrooms, and finally a large gymnasium. The grounds are most extensive, being half a mile in length and very tastefully laid out. There is a lake, a river, and many pleasure boats for rowing, a large field for sports of all sorts, a grand stand to witness the same, a rich orchard and a beautiful pleasure garden, several luxurious lawns, and many superb trees.
