LOCAL INSECT COLLECTION 19 
MINERAL ACCESSIONS 
HROUGH the Bruce Fund the Mineral Collection has received 
some attractive mineral specimens, including several species 
new to the collection and others from new localities or of un- 
usually perfect crystallographic development. Among the specimens 
is a group of lodyrite crystals from ‘Tonopah, Nevada, illustrating some 
of the hemimorphic forms described recently by Kraus and Cook, a 
handsome surface of dark-green prismatic Brochantite, a hydrous sul- 
phate of copper, from Chili and a striking veinlet of the same mineral 
in fibrous form which has been changed to red oxide of copper (Cuprite), 
possibly, in a measure, through the agency of heat. 
Among the remarkable mineral developments at Chuquicamata, 
Chili, which furnishes the Brochantite, are very beautiful light-green 
pyramidal crystals of Kréhnkite, and the collection has secured an 
admirable example of this unique occurrence. Less noteworthy though 
valuable are some specimens of minerals which possess individual interest 
for crystal perfection, and among these may be mentioned a handsome 
Apatite from Hebron, Maine, which for a long time remained an unat- 
tainable ornament of a private collection, a small perfect Spodumene 
(Kunzite) crystal in its matrix, a New Hampshire Topaz and Phenacite, 
a beautiful blue Topaz from a new locality in Texas, some ruby Corun- 
dum from North Carolina, translucent crystals (viewed through the 
shorter axis) of Phlogopite from Franklin Furnace, N. J., and a deli- 
cately arborescent native Silver. In addition to these, specimens helpful 
for the scientific illustration of their respective species have been pur- 
chased, and the collection sensibly maintained abreast of the rapidly 
increasing development of the subject, through this indispensable en- 
dowment. L. P. GRATACAP, 
THE LOCAL COLLECTION OF INSECTS 
HERE are about ten thousand species of insects occurring within 
fifty miles of New York City, but up to the present year, owing 
to the pressure of other work and the lack of funds, the Museum 
collection representing these insects attained to only twenty-five per cent
