A collection of rocks from Philadelphia and vicinity, selected 1 
mainly from the State Geological Survey Collection, has been ar~ 
ranged in the Pennsylvania and New Jersey Room, and a synopti* 
cal collection of rocks has been arranged in two cases in the old 
museum, both of which will prove of assistance to students of geol¬ 
ogy. 
Four additional cases have been added to the William S. Vaux 
Collection for the accommodation of exceptionally large crystals and* 
masses of minerals, and an additional case to the Clarence B. Moore 
Archaeological Collection. Mr. Moore has spent much time in the 
field during the year, and has added many rare and interesting spe¬ 
cimens to this collection. 
The conchological department has continued to increase under 
the constant care of the professor in that department, and the rear¬ 
rangement of a considerable portion of the bivalves has been made 
possible by the removal of part of the minerals from this gallery. 
Besides those already mentioned, there have been numerous large 
and valuable additions to the museum during the year, as will be 
seen in the appended list. 
Among them we would call attention to the valuable collection of 
marine specimens from California, presented by Mr. Harold Heath * y 
a collection of rocks and birds from South Africa, presented by Hr. 
Emil Holub, through Mr. H. G. Bryant; a collection of Coleoptera 
from Pennsylvania and New Jersey, presented by the Feldman 
Collecting Social, a collection of African insects and mollusks 
from Hr. A. Honaldson Smith ; a collection of alcoholic mammals 
of North America from S. N. Rhoads, as well as the numerous 
valuable specimens received through the year from the Zoological 
Society of Philadelphia. The collection of marine invertebrates 
preserved in formaline has also been increased through the liberal¬ 
ity of Mr. F. W. Walmsley. 
Several important improvements in the museum building are also 
noteworthy, particularly the fitting up of the receiving room at the 
east end, as an addition to the library and the renovation of the 
Council Room. 
The Curators have also, during the year, vacated one of the small' 
rooms on the library floor, and have allotted a large space on the 
basement floor of the new museum for the storage of publications. 
The Curators take this occasion to express their indebtedness to 
various members and to the Conservators of the Sections, for valu-
