The area of each plane is approximately as follows: 



Plane A = 200 sq. in. (13 sq. dm.) 



Plane B = 196 sq. in. (12 sq. dm.) 



Plane C = 113 sq. in. (7.1 sq. dm.) 



The position of these planes makes it unlikely that they were 

 developed by the blow of the meteorite in striking the earth, for one 

 at least runs nearly at right angles to the probable direction of

motion of the meteorite. Further, as stated more in detail below, 

 the striae of the slickensided surfaces run in different directions. 



The plane marked (A) in Fig. 2, Plate XLIV, runs quite nearly 

 in the direction of probable motion and it is interesting to note that 

 near each end of the meteorite irregular cracks appear which are 

 approximately parallel to this plane. Their position suggests that 

 they may have been produced by the tendency of the base of the 

 meteorite to continue its motion after the apex had been stopped by 

 striking the earth. The plane marked (C) separating Pieces 2 and 4 

 can be noted continuing on in Piece 1 as a line which extends nearly
