little book, " Florula Cestrica," he requested the assistance 

 of Mr. Michener in the work. This gave a fresh impulse 

 to his botanical studies. Dr. Darlington acknowledged his 

 indebtedness to Ezra Michener in the collection and 

 preparation of the lichens for his " Flora Gestrica," referring 

 to him as a naturalist of acumen, diligence and indomitable 

 perseverance. As a botanist, Mr. Michener was much 

 interested in the cryptogams, and did much good work in 

 their collection and study. In 1840 Mr. Michener was 

 elected a correspondent of the Academy of Natural Sciences. 

 He did much active collecting, and was thoroughly con- 

 versant with the flora of Chester County. He died a life- 

 long and active member of the Society of Friends, June 24, 

 1887, at Toughkenamon, Chester County, Pennsylvania, 

 aged ninety-two years seven months. His coffin was made 

 of the boards from the trunk of a tree, Pauloiunia, which he 

 had planted. 



He was a frequent correspondent with many of the 

 most eminent scientists of his time, among whom may be 

 mentioned Darlington, Rothrock, Curtis, Laning, Ravenel 

 and Tuckerman. Agassiz said of him " that he did not 

 belong exclusively to Chester County, Pennsylvania, or 

 America, but to the whole scientific world." *
