contains a dark-coloured glary fluid, and this is common to 
the shark tribe, but the use of such a secretion is not at pre- 
sent known. 
The spleen in all respects resembles that of the blue shark 
formerly described. 
The pancreas is situated in the angle between the pylorus 
and duodenum. It was so much broken, that its shape could 
not be ascertained; but its substance is composed of a soft 
whitish mass, intermixed with roundish bodies of a firmer 
texture. 
The liver consists of two lobes nearly equal in size. They 
occupy the anterior part of the belly, from below the giils 
to the rectum. It yielded about three hogsheads of oil No 
gall-bladder was discovered; and as a chord (like a navel 
string) consisting of twelve hepatic ducts passed from the 
liver to the duodenum, there is reason to believe that this fish 
has no gall-bladder. There is none in the piked whale. On 
cutting into the liver, the blood-vessels were found to be so 
large, that they readily admitted a man’s arm, and on pull- 
ing them the substance of the liver was readily torn in the 
direction of the smaller branches, which went off' at right 
angles to the central trunk, as regularly as those of the gills. 
The kidnies are long narrow bodies, lying on each side of 
the spine, and extending along the whole length of the ab- 
domen. The ureters run along their inner edge, and termi- 
nate in an oval cavity just within the verge of the anus, which 
has an imperfect septum separating it into two parts, the ure- 
ters opening on the opposite sides of this septum, this cavity 
must therefore be considered as the urinary bladder. 
The testicles are situated immediately behind the origin of
