followed without any break from the crown to the margin. It is 

 hardly likely that there exists another oriented meteorite with a 

 drift-effect so delicate and yet so sharply defined and running so 

 regularly over the whole of the front. 



To summarise the differences between the front and the back, they 

 are limited, apart fi'om the drift-effect, to the facts that the back is 

 flatter and has a duller crust, with somewhat shallower thumb- 

 marks. The complete absence on both surfaces of the deep hollows 

 as well as of the larger cavities which usually appear on oriented 

 meteorites is worthy of note. 



Of the sides, the slightly sloping one (Plate I., Fig. 1, and Plate 

 II., Fig. 2, on the right) likewise shows in the two places where it 

 still has its original crust the striations resulting from fusion. 

 These can be seen quite distinctly on the photograph, especially when 

 viewed with a lens, but are in reality much more strongly marked. 

 They are a direct continuation of those above desci'ibed, so that the 

 two drift-effected surfaces together form the front of the meteorite, 

 in spite of the somewhat sharp edge in which they join. 



The remaining sides, which are, on the whole, flat and steeply 

 sloping, are covered with a somewhat rough, black to brownish- 

 black crust, which only in those parts where it becomes slightly 

 wrinkled shows indications of a drift-effect directed towards the 

 back. The edges on both sides are, as has already been noted, 

 unusually sharp, and, strange to say, even sharper towards the 

 fi'ont than towards the back. Hollows and loose chondrules are 

 entirely wanting on most of the sides ; when they occur they are 

 few, and the former are but imperfectly formed. 



In several places the meteorite has been chipped. The largest 

 breakage is on one of the solid angles (Plate I., Fig. 2, and Plate II., 

 Fig. 1, below, on the right, in both cases), the weight of the missing 

 piece, shaped like a blunt triangular pyramid, being estimated at 

 1^ kg. In addition flat pieces have chipped off on several of the edges, 

 with the result that these, apparently once sharp, have become 

 bevelled. This is shown in all the views, but best in the side view 

 (Plate I., Fig. 2, below, right and left), where the breakage has also 

 been continued as two narrow strips extending from the left corner 

 to the front surface. Since all the broken parts show exactly the 

 same structure, particularly the brownish colour such as is charac- 

 teristic of secondary crust formations, and as in addition there occurs 

 on some isolated parts a bark-like crust," the splintering must have 



* It resembles that characteristic of some crystalline chondritic meteorites.
