262 PROCEEDINGS OF THE ACADEMY OF [April, 



He accompanied Leidy, Willcox, and Porter to the West in 1872, 

 and had an opportunity of observing the work of naturalists in the 

 field. He served as Dr. Leidy's assistant in the University from 

 1873 to 1876, and lectured there on anatomy and physiology. 



The position of Coroner's Physician was held by him under Dr. 

 Kingston Goddard and Dr. William Kent Gilbert from 1874 to 1880. 



Dr. Chapman was married to Hannah Naglee Megargee, daughter 

 of Samuel Megargee, December 2, 1876. The union, characterized 

 by a community of social interests, was a most happy one. The 

 Treatise on Human Physiology is affectionately dedicated by the 

 author to his wife "as a small acknowledgment of the interest evinced 

 and encouragement extended in its completion." Their summers 

 were spent in Bar Harbor where, in 1886, the house was purchased 

 which they named Mira Monte, and in which Dr. Chapman died. 

 Here for nearly thirty years he pursued his studies of the flora and 

 fauna of Mt. Desert island, the latter in a little laboratory on the 

 water's edge. Here the fishermen, all his devoted friends, brought 

 whatever of interest they succeeded in securing from the waters. 



The material progress of his summer home and the welfare of its 

 citizens, among whom he was universally popular, were to him matters 

 of active concern. He endeavored in every way in his power to min- 

 imize the distinctions between the summer colony and the permanent 

 residents. He took an active interest in the local library which 

 he served as a Director. 



He succeeded George W. Tryon, Jr., as a Curator of the Academy, 

 August 8, 1876. He held the office only until the end of the following 

 year. He was elected a member of the Council in 1880, but finding, 

 after the lapse of four months, that his other engagements interfered 

 with the discharge of his duties, he resigned. Again elected a Curator 

 in 1891, to fill the vacancy caused by the death of Dr. Leidy, he acted 

 as Chairman of the Board until the close of 1904, when he declined a 

 renomination. During his term of office he cooperated earnestly 

 with his associates in the establishment of desirable administrative 

 reforms. 



Having served as Demonstrator of Physiology in association with 

 Dr. James Aitken Meigs in the Jefferson Medical College for the ses- 

 sions of 1877 to 1880, he lectured on experimental physiology in the 

 summer course of 1878 and was Curator of the Museum in 1879-80. 

 He was given a second degree of Doctor of Medicine by the College 

 in 1878, his thesis being on Persistence of Forces in Biology. 



Dr. Meigs died November 9, 1879, shortly after beginning his course
