the other end shows (by a like considerable surface) a typical Siderolite. 
Large prominent and abundant nodules of troilite are shown 
in the great sections of Toluca, Canon Diablo and Bella Roca; 
large plates of Schreibersite in La Primitiva and Tombigbee River. 
The carbonaceous meteorites are represented by all which are 
known- Cold Bokkeveldt, Alais, Orgueil, Nagaya, and Mighei. 
The metallic veins, found penetrating some few AErolites, are well
shown in the Schoenberg and Farmington masses. We have, also, 
a small piece of the only meteorite of geological (Quaternary) age 
- the Villa Lujan, brought by us from Buenos Ayres in 1889.

Finally we have specimens of two pre-historic meteorites. One 
of these is the Anderson from the alter-mound of the Little Miami 
Valley, Ohio. The other is Casa Grande from a mummy cave of 
Chihuahua, Northen Mexico.

In frequent cases, the considerable number of specimens of the 
same fall makes it possible to show varieties of extreme form and 
of inner structure. In nearly every case we are able to show both 
the outside crust of the specimen and, by fracture or artificial section, 
its inner features.

The authenticity of the specimens has been carefully studied. 
All doubtful falls have been sternly rejected. And we have refused
to increase our list by giving duplicate names of what are undoubtedly 
of the same fall, as among Tolucas, Coahiulas, Mocs, etc. 
Out sources of supply have been in part the large museums of the 
world, everyone of which we have visited in bringing together this 
collection. 
We have adopted the general divisions of the collection of the 
British Museum- Siderites, Siderolites and AErolites. Under these 
divisions our arrangement, for ready convenience, has been alphabetical. 
We will only say in defining the fullness of the collection 
that, of the 61 classes or divisions of meteorites adopted by Brezina, 
we have all but 1; while, of the 62 types of Meunier, we have all 
but 2. Few meteorite collections in the world (we believe only 
three) have an equal number of kinds, with, at the same time, an 
average so large (2 1/2 lbs) in the weight of their individual specimens. 
(See page 21).

Each specimen is separately mounted on a choice mahogany 
pedestal, bearing a printed celluloid label. The entire collection 
fills six cases, 12 feet long by 4 feet wide, with plate-glass sides
through which, on their pedestals and shelves, the individual specimens 
may be seen and studied.
