1870.] MR. J.B. PERRIN ON BAL-ENOPTERA ROSTRATA, 811 
ceding, and was of a rounded or globular shape. It measured 6 inches 
in its long diameter, or somewhat less than half the diameter of the 
third stomach. It had, arising from the middle of its dorsal aspect, 
in an infundibuliform manner, the duodenum, or commencement of 
the small intestines. 
The girth of the first stomach at its middle or widest part mea- 
sured 30 inches, that of the second 22 inches, the third 21 inches, 
and the fourth 184 inches. 
On opening the stomachs there was found in the first ten small 
pebbles, and in the second also ten others. All the stomachs were 
perfectly empty in other respects. 
The mucous membrane presented different characters in each of 
the four stomachs. In the first it was of a pearly pinkish-white 
hue, complexly convoluted, the convolutions being continuous from 
the longitudinal rugze of the cesophagus. In the second stomach the 
colour of the mucous membrane was pale brown, the rug running 
in a transverse direction, and in the upper and lateral walls present- 
ing large and small alternations, the large ones projecting very 
prominently in the interior of the cavity. At the distal end the 
rugee were almost absent. 
In the third and fourth stomachs the mucous membrane was of 
a pale creamy-yellow colour; the rugze scanty and irregular 
The aperture between the first and second stomachs is very large, 
and readily allows of the passage of materials from one to the other. 
The aperture between the second and third stomachs is circular, and 
guarded by an annular, prominent valve. The diameter of this 
opening is about two inches, the canal afterwards becoming con- 
voluted, and, at its entrance into the third stomach, again undergoes 
dilatation. The latter aperture is also guarded by an annular 
valvular fold. The length of this canal is about 24 inches long. 
The aperture between the third and fourth stomachs is small and 
semilunar, and directed transversely. The fourth stomach passes 
directly into the intestine, the only lines of demarcation between the 
two being the abrupt termination of the large calibre and the pre- 
sence of valvulz conniventes. 
The intestines measured 72 feet 2 inches from the commencement 
of the duodenum to the cloaca. The large intestine occupied only 
5 feet 4 inches of the length. From the commencement of the 
duodenum to the first diverticulum, a little sac-like dilatation of the 
small intestine, measured 43 feet 5 inches. 
Kidneys :—Weight=2 lbs. 1 0z.; length 15 inches; width across, 
or transverse measurement, =5 inches; shape fusiform. Surface 
mapped out into comparatively regularly polygonal-shaped spaces, 
giving to the kidney a beautiful lobulated character. The diameter 
of the lobules varied from £ to an inch. The lobules could be 
readily isolated, being connected together by a very thin, delicate 
areolar tissue. The liver was similar in every essential particular to 
that of Carte and Macalister’s specimen. 
Muscles of the Shoulder and Extremity.—These presented some 
few differences from those described by Carte and Macalister.
