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 lie 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 

 1 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 (10 cm.) deep. On Plate LVII 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 square inch 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 witn 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 is 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 two inches (5 cm.). Frequently 

 the cavity within is larger and of somewhat different shape from the 

 orifice. As a rule, though, it has an approximately cylindrical shape 

 and is about the size of the orifice. Other shapes noted for the orifices
