Case 3A (East Side) and part of Case 4c.—Siderolites. 
These contain iron and stony matter in about equal proportions. 
Olivine is frequently found filling the cavities of the iron. 
These are illustrated by specimens of the Pallas iron, of the 
Rittersgriin, Hainholz, Estherville, Rockwood, and many other 
siderolites. 
Cases 5 and G. — Siderolite, or Pallasite, from Kiowa 
County, Kansas, found in 1889, nine pieces. The mass in Case 5 
weighs 465 pounds; the largest in Case 6, 344-5 pounds. There are 
also three smaller masses, and three or four slabs cut to show the 
structure of the iron, the cavities of which will be seen to be filled 
with olivine. 
Case 8.— Aerolite from Phillips County, Kansas. One large 
mass broken into 2,934 pieces. The aggregate weight of these is 
1184.5 pounds, making the largest weight of any single meteoric 
stone knownJ: e-bc colkcfed in one caco . The surface will be 
seen to be deeply pitted and oxidized. The stone as it fell struck 
upon a ledge, shattering it into a large number of pieces. All that 
could be found of these were collected, and are shown in this 
case. 
Cases 7 and 10.— Casts of notable meteorites. Collection 
showing terrestrial minerals which approximate in composition 
those found in meteorites. 
Pedestals 9 and 11.— Models of the enormous Chihua- 
hua, Mexico, meteorites, the largest known. These have remained 
until recently in the place where they originally fell, but have now 
been removed to the City of Mexico. 
Pedestal 12. — ^Two large masses of Canon Diablo, Arizona, 
meteorites, weight 1013 and 265 pounds. This locality has re- 
cently been discovered and described by Prof. A. E. Foote, and 
has yielded a large number of specimens. Recent investiga- 
tions by Mr. Geo. F. Kunz show the presence in these meteorites 
of minute diamonds.
