May, 1902. METEORITE STUDIES, I—FARRINGTON. 287 
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.) 
Pepe Wa LT 3°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 

Fic. 2. Slickensided surface of Long Island meteorite. 1. 
motion of the meteorite. Further, as stated more in detail below, 
the striz 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
