rt was extremely glandular. A well-marked muscular gullet
followed, composed of two layers of muscular fibres,--one circular
internally, and one longitudinal externally. These latter sent a slip to
the base of the arytaenoid cartilages. The mucous membrane of the gullet
had no true epidermic covering, and in this respect differed remarkably
from the first gastric compartment, from which a cuticular lining could
be peeled off, as strong as that from the sole of the foot in man. The
larynx presented that organization so well described by the illustrious
Cuvier, and which I believe to be peculiar to the whales with teeth. It
differs very much, as I explained long ago, in its arrangement from that
of Whalebone Whales,--a fact of which I think Cuvier was not aware. The
cricoid cartilage was imperfect in form; the hyo-epiglottic muscles very
strong. The proper arytaenoid were present, and strong, but did not
extend so high as in man; the thyro-arytaenoid muscles were very fully
developed. In the interior of the larynx there were no projections nor
ventricles, no cuneiform cartilages, nor cornicula laryngis. The rings
of the trachea formed complete circles.

_Stomach._--The cuticular lining is limited to the first cavity or
compartment. It is in the second compartment that is found the curious
glandular arrangement first, I believe, described by me in the
'Transactions of the Royal Society of Edinburgh.' This structure is most
probably not limited to the second compartment. There are four distinct
compartments in the stomach of this animal. A dilated duodenum follows,
6 inches in length. It is possible that this may have been in some
instances mistaken for a stomach. The valvulae conniventes commence with
the jejunum; these are longitudinal, and extend to within about 6 inches
of the anus, terminating at a point where the intestine seems enlarged.
The length of the intestines, large and small, was 90 feet;
circumference generally about 2 inches. Thousands and tens of thousands
of parasitical worms were found in the stomach, but none in the
intestine. In the stomach also we found four mandibles of the
cuttlefish, but no remains of anything in the intestines, and no
parasites.

_Heart and Vessels._--The heart weighed exactly one pound. The
Eustachian valve was small, that of Thebesius imperfect. The aorta
proceeded for about 3 inches of its course before giving off any
branches. At a point corresponding to the 15th or 16th lumb
