260 Mr. Atprerson on a Whale of the Spermaceti Tribe. 
Along the sides of the sacs containing the spermaceti, as 
well as those of the breathing tube, ran innumerable thick and 
strong tendons*, terminating in the snout; evidently an apparatus 
for moving the snout, and the lips of the external orifice of the 
breathing tube. 
The snout overhung considerably the lower jaw. I am not 
aware that this was measured; indeed from the very first, the 
lower jaw was dislocated, and projected on the left side of the 
animal, from under the upper lip, at nearly a right angle to the 
body. 
The Eye.—This organ was not examined until the 8th of 
May: the parts offered for dissection consisted simply of the 
ball of the eye, together with the sheath which contains the 
straight muscles of the eye, enveloping the optic nerve, and were 
in no state to give any satisfactory result. The connexions 
with the adjoining parts had all been removed, through the 
ignorance of the workmen. The cornea was very much sunk 
and flaccid, and the conjunctiva had a dull bluish cast. 
On clearing away the insertions of the cut muscles, the ball 
of the eyet was measured. 
Its transverse diameter measured 2.35 inches. 
Diameter in the direction of the axis of the eye measured 
2.25 inches. This latter measurement taken on the supposition 
that the cornea was originally flat. 
The color of the iris, as well as could be judged from its 
decomposed state, was bluish-brown; very dark; the pupil was 
transverse, as in ruminating animals. 
* Some of these were drawn out of the head by the by-standers, upwards of nine 
feet in length. 
+ These measurements were all taken by means of a pair of graduated callipers.
