assistance. He was killed while walking across the Penn- 

 sylvania Railroad track at this point, by being struck by a 

 train, on July 11, 1889. 



Mr. McCalla's personal infirmity, his extreme deafness, 

 naturally limited the circle of his intimates, but to those 

 who were fortunate enough to know him well, he was 

 recognized as a brave, pure-minded, upright, unselfish man ; 

 an earnest and untiring student and devoted friend. 



J. M. ANDERS. 



Dr. J. M. Anders, a prominent physician of the city, 

 can hardly be classed among the botanists of Philadelphia. 

 He, however, deserves notice in this book as the author of 

 two papers dealing with subjects on the medical side of 

 botany. The first paper, entitled, " On the Transpiration 

 of Plants," published in the American Naturalist, March, 

 1878, 160, was the result of study and experimentation 

 on the plants grown in Horticultural Hall, Fairmount 

 Park. His other paper, "Sanitary Influence of Forest 

 Growth," was published in the Proceedings of the Philadelphia 

 County Medical Society, January 29, 1885. A book appeared 

 in 1887 on the same subject.* 



CHARLES HENRY KAIN. 



Charles Henry Kain was born in New Jersey, and 

 received his education in the schools of that State, including 

 the Trenton Classical Academy and the New Jersey State 

 Normal School, which he left before graduating, in order to 

 pursue classical studies with a view of entering college.
