OTHER INTERESTS 
Michener naturally included the lichens in his studies and sent 
numerous specimens to Tuckerman for identification (see 12). 
That he was a collector of no mean ability is shown by the fact that 
in his list of lichens of Chester County, published in the third edition 
of Darlington’s Flora Cestrica, 1853, there are included (3, p. 456) 
‘about 20 species never before published in this country, one-half 
of which are entirely new.” These new species are all described 
by Tuckerman, who named one species Biatora Micheneri, in 
Michener’s honor. Tuckerman also named a species in this list in 
honor of the county, Verrucaria cestrensis. Tuckerman presented 
Michener with a complete set of his ‘‘Lichenes Americae Septen- 
trionalis,’”’ inscribed 
“Dno. E. MICHENER, 
AUCTOR 
to AuG. 1852.” 
These volumes, which bear notes in Michener’s hand, are now in 
the possession of the writers. 
Darlington’s impression of Michener is frankly stated in the 
introduction to this edition of the Flora Cestrica, in which he 
refers to him as “‘a naturalist from whose acumen, diligence, and 
indomitable perseverance we may fairly expect as thorough an 
exploration of every department of our Cryptogamy, as the active 
duties of his profession and the life-time of an Individual will 
permit.” ; 
Michener’s interest in natural science was by no means con- 
fined to botany. He was co-author with Dr. William D. Hartman 
of a work on the shells of Chester County, and prepared a con- 
siderable portion of the section on “Zoology”’ in the history of 
Chester County compiled by Futhey and Cope (4). In this 
there are numerous footnotes signed with his initials, indicating 
close field observations on the habits of birds. 
In the manuscript ‘‘Catalogue of the Museum presented to 
Swarthmore” are listed with Michener’s usual care four hundred 
and twenty-six species of mammals, birds, and reptiles, arranged 
in accordance with the nomenclature of the best authorities of 
his time. The greater portion of these specimens (8, p. 202) had
