men, ;',th its linear dimensions. 
From tip to tip of the broken 
horns measures 56 inches; the 
right being 2 feet, and the left 
18 inches long; the circumfer- 
ence of the nucleus of the horns 
at base is 17 inches, and at the 
distance of 18 inches from the 
head the circumference is 144 
inches. The frontal bone be- 
tween the horns is 14 inches in 
breadth ; between the external 
angles of the orbits 143 inches ; 
between the internal angles of 
\ the orbits 113 inches; and the 
length of the bone from the or- 
bital to the occipital portion is 
15 inches. The bones of the 
horns are nearly round, and they 
have a slight curvature upwards 
and forwards ; and when entire, 
the bony parts must have meas- 
ured, at a reasonable estimate, 
about 4 feet; and allowing the 
increase in length by the addi- 
tion of the horny parts to have 
been only a foot, it would give 
a probable distance between the 
tips of the horns to be at least 
11 feet. 
The frontal bone is nearly 
plane anteriorly, and the horns 
arise laterally from a level with 
this plane; but the bone bulges about 24 inches in the opi 
portion above the horns, as shown in the figure.
