Obituary. 



JosiAH DwiGHT Whitney, one of the pioneers among Ameri- 

 can geologists, died on August 19th aged seventy-six years. 



He was born in Northampton, Mass., November 23d, 1819, was 

 graduated at Yale in 1839 and began his active geological work 

 as assistant geologist under Charles T. Jackson on the survey of 

 New Hampshire in 1840, where he was engaged for two years. 

 In 1847 he, with J. W. Foster, was appointed by the United 

 States government to assist Jackson in the geological exploration 

 of the Lake Superior region. After two years this work was 

 committed to Foster and Whitney alone, and the results of their 

 labors were published in 1849, 1850 and 1851 in " Synopsis of 

 the explorations of the Geological Corps in the Lake Superior 

 Land District in the Northern Peninsula " (Washington, 1849), 

 and the "Report on the Geology and Topography of a portion 

 of the Lake Superior Land District in the State of Michigan " 

 (Part I, Copper Lands, 1850 ; Part II, The Iron Region, 1851). 



In 1855 he began geological work in Iowa, associated with 

 James Hall ; the results of this survey were published as " Reports 

 on the Geological Survey of Iowa" (2 vols., Albany, 1858-9); 

 the geological part being contributed by Whitney, James Hall 

 furnishing the paleontological volume. Next Professor Whitney 

 undertook the investigation of the lead region in Wisconsin and 

 adjoining territory, the account of which was published in the 

 " Report on the Geological Survey of the State of Wisconsin " 

 (Albany, 1862). In this survey James Hall was also associated 

 with him as paleontologist. 



In 1860, at the close of the survey in Wisconsin, Professor 

 Whitney was appointed State Geologist of California. Here 

 he organized and carried out a thorough survey of the topograph- 

 ical, geological and natural history features of the state, and pub- 

 lished the results in a series of six volumes entitled '* Geological 

 Survey of California" (Cambridge, 1864-70), besides annual 

 reports and papers in the scientific journals, giving accounts of 

 the progress of the survey. This was his most elaborate work 

 and that in which his best powers were shown. During the 

 execution of these local geological surveys he published several 

 works of a more general nature. An English translation of 

 Berzelius's "Use of the Blowpipe" was published in 1845. In 

 1854 appeared "The Metallic Wealth of the United States
