NO. 1273. A NEW METEORITE FROM KANSAS— MERRILL. 913 
EXPLANATION OF PLATES. 
Fig. 1. The 5,460-gram mass, as found. 
2. The 6,725-gram mass, as found. 
The 2,048-gram mass, cut in halves. Size of faces shown, about 10 by 11 cm. 
The enlarged area shown in Plate LV appears at a spot just above and to the right 
of the center in tig. 1. In fig. 2, just to the left of center, are shown like areas 
consisting exteriorly of metallic iron with interiorly the spongy iron and lawrencite. 
This last shows the interior, more compact, central portion mentioned on page 909. 
PLATE LII. 
Slice, slightly reduced, from the 6,725-gram mass shown in fig. 2 of Plate L. The 
dark areas are olivine; the white, the metallic portions. 
PLATE LIII. 
Photographic enlargement of about three diameters. The dark areas are in all 
cases olivine; the white (1), nickel-iron; (2), schreibersite; and (3), troilite. 
In fig. 1 a large fractured olivine is shown in the lower center, with nickel-iron (1) 
above, which extends downward into the fracture for a distance of about 1 milli- 
meter, where it stops abruptly, the remainder of the fracture being occupied by 
schreibersite (2). In fig. 3 the schreibersite (2) is shown both in granular form and 
as a thin plate lying between the troilite (3) and nickel-iron (1). 
PLATE LIV. 
Photomicrographs of thin sections enlarged about ten diameters. The colorless 
areas (1) are olivine; the white lines (2), schreibersite; the dark areas (3), bordered 
by schreibersite (2), are troilite. The other dark, nearly black areas, not numbered, 
are secondary iron-oxides. 
PLATE LV. 
Photographic enlargement of about five diameters. The dark outer areas are oli- 
vine; the white ( 1 ), nickel-iron. The dark areas (3) within the nickel-iron are spongy 
aggregates of iron, lawrencite, or troilite. Extending outward from the metallic por- 
tions and into the spongy mass are acicular crystals of nickel-iron (4). Between the 
nickel-iron (1) and the spongy areas is commonly a thin plate of schreibersite (2), 
which can not, in the illustration, be differentiated from the nickel-iron.
