He is, for instance, credited by Ashhurst ("Principles and Practice of Surgery") with having tre- phined bone lor suppurative osteomyelitis in 1757, making him one of the first known to have done that operation. He lived at Castle Hill in Albemarle County, which he acquired by his marriage with the widow of Nicholas Merriweather, and during his life filled many important positions of trust, and was the guardian of Thomas Jeffer- son, besides being the intimate friend of Gen- eral Washington to whom he was related by marriage.

In 1853 he began the study of medicine and graduated at the Uni- versity of the City of New York Medical Department, 1855, and afterwards served in a hospital in New York.
