“December, 1896.” [1897]. 
In 1898, Professor Barnes published a botanical textbook of 428 pages 
under the title of “ Plant life considered with special reference to form and 
function.” An abridged and simplified edition of this work, with the title 
“Outlines of plant life with special reference to form and function,” 
appeared two years later. 
He was the author, also, of numerous scholarly papers relating to the 
physiology of plants and of many critical reviews. His reviews were occa- 
sionally a little caustic, but his opinions were always interesting and stimu- 
lating. 
Dr. Barnes was active in the American Association for the Advance- 
ment of Science, having been secretary of Section G in 1894, secretary of the 
Council in 1895. general secretary in 1896, and vice-president (chairman of 
Section G) in 1899. He was one of the founders of the Botanical Society 
of America, its secretary from 1894 to 1898, and its president in 1903. 
Though Professor Barnes was still in the prime of vigorous manhood, he was 
generally looked upon as belonging to the older circle of American botanists 
— a feeling that was due less to his years' than to his long- established posi- 
tion among the leaders. His was a personality that American botany could 
ill afford to lose. And, indeed, it is not lost, for its influence still endures.
