TRAILL GREEN. 



Dr. Traill Green * was born at Easton, Pennsylvania, 

 May 25, 1813, and died in Kaston, Pennsylvania, April 29, 

 1897. From early youth he devoted himself to the study 

 of natural history. His interest in science led him to 

 medicine. Entering the medical school of the University 

 of Pennsylvania, he graduated from that institution in 

 1835. 



He returned to Easton and established a practice there. 

 In 1837 he was made Professor of Chemistry at Lafayette 

 College. He received the degree of A. M. from Rutgers in 

 1841, and was later called to the chair of natural science 

 at Marshall College, in Mercersburg, Pennsylvania (1841- 

 1848). Here he pursued botany to considerable extent. In 

 1866 Washington and Jefferson University conferred the 

 degree of LL. D. upon him. In 1865 he was elected Pro- 

 fessor of Natural Science at Lafayette College. He presented 

 the astronomical laboratory to Lafayette College, and was 

 always deeply interested in science. From 1865-1891 he 

 was Professor of Chemistry in the same institution. Dr. 

 Green w^as a member of many different scientific societies, 

 and w^as an author of note, having written a number of 

 scientific books and articles. " Zoological and Floral Dis- 

 tribution of the United States " (1861) seems to have been 

 the only botanical article from his pen. With all the 

 labor implied in an extensive practice and a professorship, 

 he found time for other w^ork. He had classes of boys and 

 girls in botany, and it was a rare season when he was not 

 instructing somebody in the natural sciences.
