DALL, Charles Henry Appleton (dal), clergyman, born in Baltimore, Maryland, 12 February 1816; died in Calcutta, British India, 18 July 1886. He was educated in the Boston public and Latin schools, and was graduated at Harvard in 1837, and at Harvard divinity-school in 1840. In November 1841, he was ordained an evangelist of the Unitarian Church in St. Louis, after which he was settled in Baltimore, Maryland, Portsmouth, New Hampshire, Needham, Massachusetts, and Toronto, Canada. Failing health, from excessive pastoral duties, with a preference for missionary work, induced him to take up that occupation as his life labor. He became the first foreign missionary of the Unitarian Church in America, and in February 1855, sailed for Calcutta. There he instituted the first girls' school for natives, the first school for homeless and friendless children, and the first children's temperance society.

Mr. Dall was elected a member of the American oriental society and the Asiatic society of Bengal, and a foreign associate of the Hungarian Unitarian consistory. He was the author of many tracts, educational and moral, for circulation in British India, a small work on the Suez Canal, many hymns and devotional poems, and notes of travel contributed to periodicals in the United States and India. The number of pamphlets written by Mr. Dall in India exceeded one hundred, and many of them were several times reprinted in response to a demand from the natives for whose instruction they were intended.

--His wife, Caroline Wells Dall, daughter of Mark Healey, born in Boston, Massachusetts, 22 June 1822, was educated at private schools and academies, after which she became a teacher, and in 1840 was made vice-principal of the then celebrated "Miss English's school for young ladies," in Georgetown, D.C. In September 1844, she married Mr. Dall, and, although occupied thenceforth with duties incidental to the life of a clergyman's wife, she continued her studies and literary activity. Her early work was especially devoted to reform topics, principally the opening of new fields of labor to women. Mrs. Dall's later labors have been chiefly literary and critical. In 1877 she received the degree of LL.D. from Alfred University. She has published many books, among which are "Essavs and Sketches" (Boston, 1849); "Historical Pictures Retouched, a Volume of Miscellanies" (1859); "Woman's Right to Labor" (1860); "Life of Dr. Marie Zakrewska, being a Practical Illustration of ' Woman's Right to Labor'" (1860); " Woman's Rights under the Law " (1861); "Sunshine; A Name for a Popular Lecture on Health" (1864); "The College, the Market, and the Court, or Woman's Relation to Education, Employment, and Citizenship" (1867); "Egypt's Place in History " (1868): " Patty Gray's Journey to the Cotton Islands" (3 vols., 1869-'70); "Romance of the Association, or One Last Glimpse of Charlotte Temple and Eliza Wharton" (1875); " My First Holiday, or Letters Home from Colorado, Utah, and California" (1881); and " What we Really Know about Shakespeare" (1885).

--Their son, William Healey Dall, naturalist, born in Boston, Massachusetts, 21 August 1845, was educated at the Boston public schools, and then became a special pupil in natural sciences under Louis Agassiz, and in anatomy and medicine under Jeffries Wwnan and Daniel Brainerd. In 1865 he was appointed lieutenant in the International telegraph expedition, and in this capacity visited Alaska in 1865-'8. >From 1871 till 1880 he was assistant to the U. S. coast survey, and under its direction spent the years 1871 till 1874, and 1884 in that district. His work, beside the exploration and description of the geography, included the anthropology, natural history, and geology of the Alaskan and adjacent regions. From the fieldwork and collections have resulted maps, memoirs, coast pilot, and papers on these subjects or branches of them. From 1884 till 1886 he was paleontologist to the U. S. geological survey, and since 1869 he has been honorary curator of the department of mollusks in the U. S. national museum. In this office he has made studies of recent and fossil mollusks of the world, and especially of North America, from which new information has been derived concerning the brachiopoda, patellidae, chitonidae, and the mollusk-fauna of the deep sea. These studies have grown out of those devoted to the fauna of northwestern America and eastern Siberia. Mr. Dall has been honored with elections to nearly all of the scientific societies in this country, and to many abroad.

In 1882 and in 1885 he was vice-president of the American association for the advancement of science, and presided over the sections of biology and anthropology. His scientific papers include about two hundred titles. Among the separate books are "Alaska and its Resources "(Boston, 1870); "Tribes of the Extreme Northwest" (Washington, 1877); "Coast Pilot of Alaska, Appendix I., Meteorology and Bibliography" (1879); "The Currents and Temperatures of Bering Sea and the Adjacent Waters" (1.882); "Pacific Coast Pilot, and Islands of Alaska, Dixon Entrance to Yakutat Bay, with the Inland Passage" (1883); "Prehistoric America," by the Marquis de Nadaillac, edited (New York, 1885); and "Report on the 3lollusca Bra-ehipoda and Pelecypoda" of the Blake dredging expedition in the West Indies (Cambridge, 1886).
