The Academy of Natural Sciences of Philadelphia was founded 
March ı2th, ı812 and from the outset the department of botany received 
attention. The first contribution to the Academy’s herbarium consisted of a 
collection of plants made in the environs of Paris and presented by NICHOLAS 
S. PARMENTIER. During the years which followed, this nucleus received con- 
stant accretions and the names of CoLLIns, ELLIOTT, PURSH, BALDWIN, LE 
CONTE, CONRAD, NUTTALL, TORREY and PICKERING are inscribed on many of 
the tickets attached to the plant sheets. In 1834, the Academy received by 
bequest the collections made by LEwıs DAVID DE SCHWEINITZ. Other valuable 
contributions followed among which may be specified the POITEAU collection 
of Santo Domingo plants, Chilian plants from STILES and RUSCHENBERGER;

Sandwich Islands; the ASHMEAD collection of marine algae; LESQUEREUX’S
