This is a much laterally compressed fragment lacking base and stun- 

 niit and also a consideralile part of one side, which is now one of the edges 

 of what is little more than a slal). The fractures at the ends are obhque, 

 especially the upper one, so that the height, which is 26 cm. on the longest 

 side, is only 16 cm. on the shortest. The basal fracture is also very 

 o))liciue in the short direction, so that one of the flat sides is 7 cm. to 8 cm. 

 longer than the other. The missing part from the side (edge) included 

 the whole of the armor and extended to the medulla. One side of the 

 specimen is very much worn, the other much less so; the edge that remains 

 is also in a fair state of preservation. The rock is rather light colored, Init 

 heavy and solid. (Locahty: PI. LXXX, Xo. 67.)

This is a fragment apparently from near or at the base of a moderate- 

 sized trunk which was \'ery much laterally compressed. It includes part 

 of both of the flat sides, but more of one than of the other, and the whole 

 of one of the narrow sides or edges. The vertical fracture is oblique to the 

 major axis of a cross section, and falls considerably on one side of the 

 center, preserving the smaller piece. The lateral fracture is oblique to the 

 axis, so as to make the broader side longer than the narrower one. Viewed 

 from alcove, all the parts are seen to ))e about equally afTected In' the 

 flattening. The specimen is thoroughly silicified, hard, fine grained, and 

 rather heavy, of a dark-brown color. It is 18 cm. high measured on the 

 longer side. Its maximum width is 19 cm., which is that of the broader 

 side. Its thickness is 10 cm., which is probably somewhat less than the 

 minor axis of a cross section. The major axis can of course only be con- 

 jectured, Ijut it was probably 25 cm. or 30 cm., the portion of it that 

 remains l)eing 14 cm. The whole amount of siu'face preserved, or partial 

 girth, is 33 cm. (Locality : PI. LXXX, Xo. 52a.)
