cores near the roots 7 inches 1 line. Another 1 have measured, 

 wliose breadth above the upper margin of the orbits was 7 inches 

 5 Hues : this measured between the horns upward 5 inches 2 lines. 

 The length of the frontal bone 8 inches 4 lines. The horn-cores 

 are sometimes flatabove^ and rounded underneath. In a younger 

 specimen, probably a cow, the horn-cores are exceedingly small, 

 scarcely more than 3 inches long, and at the root 4 inches 2 lines 

 in circumference. This species is however always knoAvn by a 

 protuberance upon the upper part of the forehead in the front, 

 and an indenting behind. The usual dimensions of young speci- 

 mens are as follows : —

The other parts of the Skeleton. — Atlas in form like that of 

 the tame ox ; the edges of the wings a little reflected, and behind 

 a little broader ; the posterior articular processes small, short ; the 

 knob of the upper arch large, thick ; of the under arch more 

 compressed over the back edge. Axis like that of the tame ox, 

 but the canal in process, odontoid, not so roundly excavated ; 

 the spinous process, spinos. has the front edge angular. The 

 rest of the skeleton most like that of the tame ox, but each bone, 

 in proportion to the length, is more slender and thin. Atlas : 

 the breadth over the wings 4 inches 5 lines, under the length of 

 the curve 1:3; axis about 3 inches. The length of shoulder- 

 blade 11:4, breadth 6:1; from cav. glen, to spin. 1 : 7 ; os hu-
