JUNE, 1910. METEORITE StupiEs III — FarRINGTON. C7 
and relief of the surface. The front side is highly corrugated by 
deep and irregular channelings, pittings, and furrowings. The rear 
side is relatively smooth but with broad, shallow pittings. The 
features of the front side of the meteorite while very irregular may be 
classed as knobs, furrows, large and small pits and cylindrical holes. 
Of these the knobs lhe between irregularly coursing furrows which 
leave the metal standing out in prominences, ranging in size 
from that of a man’s fist down. These knobs are especially notice- 
able toward the apex of the cone, so that this has none of the smooth- 
ness which is often observed in meteorites of this form. The furrows 
are very irregular in their course but in a general way may be said 
to radiate outward from the center. They are shallow and sinuous, 
with the ridges between them usually broad and rounded. An 
average width for the furrows is one-half inch (1 cm.). Interspersed 
with and interrupting the furrows are shallow, shell-shaped pits from 
— tO 3 inches (2.5 to 7.5 cm.) in diameter. These are the small pits 
referred to. The large pits differ in shape and character from the 
small pits, since they penetrate deeply into the mass of the meteorite. 
The largest of these pits is a bowl-like depression about nine inches 
(23 cm.) in diameter and four inches (10cm.) deep. On Plate LVIL it 
may be seen near the base of the meteorite. The contour and sur- 
face of this pit are irregular but it is much the deepest and largest 
depression observed. Perhaps the most interesting feature in regard 
to it is the occurrence, spread over the bottom in two places covering 
about one squareinch each, of a crust of black, magnetic iron oxide. 
This adheres very firmly to the metal which it covers so that it can 
only be removed by blows with a hammer and chisel. It is con- 
tinuous as a broad patch in the two places where it occurs but the 
two patches, while situated near together, do not join. The thick- 
ness of one of these patches is about 2 mm., that of the other 1s much 
less at the thickest point and dwindles away to nothing. The sur- 
face of the thicker patch is rough and corrugated. 
The cylindrical holes referred to occur irregularly over the surface, 
not being grouped or lineally arranged so far as can be determined. 
Of these 35 may be counted with orifices varying from one-fourth of 
an inch (5 mm.) to one and one-fourth inches (3 cm.) in diameter. The 
majority are about one inch (2.5 cm.) in diameter. They penetrate 
to various depths the deepest being twoinches (5 cm.). Frequently 
the cavity within is larger and of somewhat different shape from the 
orifice. Asa rule, though, it has an approximately cylindrical shape 
and is about the size of the orifice. Other shapes noted for the orifices
