which received on its dorsal aspect the conjoined pancreatico- 
hepatic duct. The cesophageal paunch contained several pints 
of fluid, with the beaks and eyes of cuttle-fish. The cardiac 
chamber contained the partially digested mantles of thirty- 
four cuttle-fish, with quantities of eyes and beaks. 
The intestine contained mucus; at the duodenal end it 
was fawn or salmon coloured; lower down it was bile stained; 
but in the last few feet it was stained a rich brown colour. 
From its tint I was led to think that it contained sepia, 
derived from the ink-bag of the cuttle-fish, on which the 
animal fed. The coloured mucus was digested in water, 
when the colouring matter was dissolved. It was then 
precipitated from the aqueous solution by the addition of 
spirit, when a rich brown pigment was obtained, possessing 
the properties of sepia, and which was subsequently used in 
the preparation of some drawings of the animal’s viscera. 
From the fact that the mucus, in something like the upper 
three-fourths of the intestinal tract, was unstained by sepia, 
it would seem as if the wall of the ink-bag had remained 
unruptured, and its contents undiffused through the mucus, 
until it had passed along a large part of the intestinal tube. 
It has been shown by myself and others that cuttle-fish 
are a not unusual food for toothed whales. This has long 
been known as regards Hyperoodon, in the stomachs of 
several specimens of which the horny beaks and other parts 
of cephalopods have been seen.!’ Mr Beale states? that the 
food of the sperm whale consists almost wholly of the 
“squid” or “sepia octopus,” though at times when near the 
shore it may take bony fish; Mr Bennett, in his “ Whaling 
Voyage,”® confirms the statement that the main food is 
-cuttle-fish, and he also mentions that he has seen a bony fish 
which was ejected from the stomach of a sperm whale on 
being attacked. From my own dissection I have reason to 
think that Sowerby’s whale may also feed on cuttle-fish. 
Mr Robert Gray has repeatedly found the remains of cuttle- 
fish, probably Gonatus fabricti, in the stomach of the
