536 CHARLES UPHAM SHEPARD, 



alogist, Mobs, was adopted as to nomenclature and as to the natural 

 history idea of mineral species. The second or descriptive part of the 

 work, containing the descriptions of the species arranged in alphabeti- 

 cal order, appeared in 1835. This delay in its publication was partly 

 owing to Professor Shepard's acceptance from the general government, 

 for the winter of 1832-33, of an appointment as an associate with 

 Professor Sillimau, for the investigation of the methods of sugar culture 

 and manufacture in the Southern States, and to the preparation of his 

 report on the subject, which was incorporated with that of Professor 

 Sillimau, made in 1833 to the Secretary of the Treasury. In the same 

 year, 1835, he joined Dr. Percival, by appointment from the State 

 legislature, in the Geological Survey of Connecticut ; and two years 

 later, in 1837, appeared his excellent report on the mineralogy and 

 mineral products of the State. 



His professorial work after 1832 was divided between New Haven, 

 Conn., Amherst, Mass., and Charleston, S. C. To his duties at Yale, 

 under Professor Sillimau, were added those of Lecturer in Natural 

 History, which position he held for fifteen years. From 1845 to 1852, 

 and from 18G1 to 1877, he occupied the chair of Chemistry and Natural 

 History in Amherst College. In 1854, he was called to the Professor- 

 ship of Chemistry in the South Carolina Medical College at Charles- 

 ton ; he continued there until 1861, and again resumed the duties of 

 the chair in 1865, after the civil war, resigning them finally in 1869, 

 when his son, Charles U. Shepard, Jr., was appointed his successor. 



These university engagements interrupted but little his miueralogical 

 work. His first new species, Microlite, was announced in 1835, War- 

 wickite in 1838, and Danburite in 1839. Other discoveries followed 

 these, occasionally of new species, often of kinds not before identified 

 on the continent. 



Professor Shepard's private collection of minerals, under so great 

 personal activity, became large and choice, surpassing all others on the 

 continent. On retiring from his professorship at Amherst the whole 

 was purchased by Amherst College. Unfortunately, it passed from 

 under his care to a building that was not fire-proof, and one night in 

 1880 it was nearly all destroyed. Professor Shepard did not cease 

 collecting when he and his cabinet parted ; but with his old zeal re- 

 doubled by the sight of empty shelves and drawers, he soon had again 

 a large collection : and it continued to increase and to grow in interest 

 with him to the close of his life. 



Professor Shepard early commenced also the collection and study of 

 meteorites, and throuirh his life these shared with minerals in his affec-
