G. F. Kunz—Meteoric Iron from Arkansas. 497 
(89™) while the Agram measures 154 by 12 inches. <A high 
ridge, 5 inches high at the highest point (12°5™), runs through 
the center. One half of the mass is not over 3 inches (7°5™) 
thick, part of it is only 2 inches (5%), and around the edge it 
1S only one inch or less. It is only exceeded in size among the 
irons seen to fall by the Nejed, Central Arabia, now in the British 
Moseum, which fell in the spring of 1865 and weighs 59°420 
kilos. The weight is 1074 lbs. (44°218 kilos), and it is intact 
with the exception of three small points, weighing not more 
than two ounces in all, which were broken off. One of these 
is seen in the etched figure, another was sent to Professor Clarke 
by Colonel Betten to be analyzed, and the third piece was lost. 
The two sides are wholly dissimilar. (See Plate XIIL)* In 
fact, one would scarcely supppse that they belonged to the same 
mass. The upper side is ridged and deeply dented, while the 
lower side is flat and covered with shallow, but very large pittings. 
On top the colorisin many places almost tin-white without any 
coating whatever, and the pittings are very deep and usually 
quite long, like finger depressions, made in potter’s clay. 
These depressions measure from 2™ to 4°%™ and from 1™ to 4°™. 
This side is remarkable for strize showing the flow and burning 
and all running from the center toward the edge, identical with 
those in the Rowton, Nedagolla and Mazapil irons, but on a 
larger scale. Some of them are thinner than a hair and yet 
twice as high (like a high knife-edge), and they. are from one 
to four inches long. In one space of 5™ twenty are - arranged 
side by side, and on one small part which is black, there are 
50 lines in one inch of space (25™"), all running in the same di- 
rection. Near all the pointed edges the fused metal has flowed 
and cooled soas to hang like falling water. The striz and 
marks of flowing are around the edges of the upper surface, 
(Plate XIII, fig. 1.) On the under side pittings are very 
shallow but much broader, one depression, apparently made 
up of four pittings being 20° long and 95° wide. The 
whole side is coated with a black crust, 1™™ thick and hav- 
ing minute round bead-like markings. On one of the in- 
dentations of the lower edge the crust has a strikingly 
fused appearance as if a flame had been blown on it from 
the other side. In reality this edge is undoubtedly the place 
where a greater amount of burning took place when the body 
was passing through the air. Seven small, bead-like lumps, 
from 5™™ to 10™™ in size, which are visible on this side, are 
drops of metal that were entirely melted and flowed and cooled 
so that thev resemble drops of a thick liquid. There are also 
to be seen what appear to be cracks, 15 in number and nearly

productions direct from the photograph.
