and Admire, Kansas, meteorites are shown, while other falls are 
represented by sections. In the same case are shown specimens 
of terrestrial iron, which has a composition resembling that of 
meteoric iron. Santa Catharina, Brazil; Ovifak, Greenland; 
and Awarua, New Zealand, are among the localities thus repre- 
sented. 
Following the iron-stone meteorites are placed the iron me- 
teorites, about one hundred and thirty falls of which are repre- 
sented. The specimens are chiefly sections and most of these 
are polished and etched in order to show the characteristic fig- 
ures. Especially well represented falls are those of Kenton 
county, Kentucky, Rodeo, Mexico, Indian Valley, Virginia, and 
Colfax, North Carolina. 
The casts in the bays of the cases show the form, size, and 
surface characters of the meteorites represented. As the 
meteorite itself is usually cut up and distributed these casts 
afford the only record of such characters. Meteorites of 
remarkable form thus represented are those of Babb’s Mill, 
which is cigar-shaped, those of Kokstad and Hex river. 
South Africa, shaped like a large lower jaw, and Charlotte 
and Boogaldi which are drop or pear shaped. A conical 
shape is also common, the apex of the cone having been the 
front side in falling. 
On the north wall of the haU is a large map showing the dis- 
tribution of known meteorite falls in the United States.

SYSTEMATIC MINERALOGY. 
This collection numbers about io,ooo specimens and illus- 
trates the different species of minerals obtained from various 
localities of the world. The arrangement is in accordance 
with the system of Dana in the following order; Elements, sul- 
phides, chlorides, fluorides, oxides, carbonates, silicates, phos- 
phates, sulphates and hydrocarbons. The smaller specimens 
are placed in the floor cases, the larger in the wall cases. The 
series begins with the elements at the left of the entrance from 
Hall 62, then follows down this side of the hall and up the other 
and then passes to Hall 64. The order is also indicated on each 
specimen by the number placed at the left on its label. This 
shows its number in Dana’s system. The specimen labels show
