62 THE NAUTILUS. 



he removed to Grand Rapids, Michigan, and resided there continu- 

 ously until his death. From 1855 to 1857 he was engaged in the- 

 drug business, but having been ruined by the destruction of his store 

 by fire in that year, he resumed the active practice of his profession 

 in which he continued until overtaken by his last illness. 



He made a specialty of surgery and acquired a large and success- 

 ful practice. He was a member of the American Medical Associa- 

 tion, the Michigan State Medical Society and the Grand Rapids 

 Medical and Surgical Society, and, by the latter two, was, at differ- 

 ent times, honored with the presidency. He was the author of a 

 number of papers on medical and surgical subjects, which appeared 

 in the proceedings of these societies and in different medical journals. 

 He was also a member of the American Association for the Ad- 

 vancement of Science, the Academy of Natural Sciences of Philadel- 

 phia, and other scientific societies. 



Upon the breaking out of the war in 1861, he was commissioned 

 surgeon of the First Michigan Regiment of Engineers and Mechan- 

 ics, and remained in the service until 1864, when he was mustered 

 out with his regiment. During the winter of 1862-3, he was Post 

 Medical Director at Harrodsburg, Ky., where 1,500 Confederate 

 wounded bad been left by General Bragg in his retreat from Ken- 

 tucky after the battle of Perryville. 



From an early day, Dr. DeCamp was an active and enthusiastic 

 student of natural history. Geology, botany, ornithology, entomol- 

 ogy and conchology all received his attention and contributed to the 

 fine collection which, in course of many years collecting, was accu- 

 mulated by him. 



It was conchology, however, that, from the time of his removal to 

 Grand Rapids, especially occupied his attention, and his work in this 

 department will be his most lasting monument. 



He was an assiduous collector. During his army life he took ad- 

 vantage of his opportunities in the south to pursue his favorite study 

 and thereby acquired many interesting species. This material was 

 forwarded by him to Mr. Currier, and by the latter to Dr. Isaac Lea 

 and other eastern naturalists for determination. A somewhat haty 

 review of the literature has shown that the following new species 

 were discovered by him during this period : 



Pleurocera currierianum Lea. 



Pleurocera bicinctum Try on. 



Goniobasis decampii Lea.
