730 CAPT. D. GRAY ON THE BO[TLENOSE WHALE. [Dec. 19, 
hundredweight of spermaceti to each ton of oil, being exactly the 
same proportion that the Greenland Whale yields of whalebone to 
the ton of oil. 
In the female, in front of the bones of the head there is a cavity 
containing a small quantity of oil which is quite colourless and 
twice the density of that rendered fromthe blubber. In the males, 
instead of oil there is a solid lump of fat similar in shape to, and 
about twice the size of, a large water-melon. 
The following is an analysis of their oil, as compared with sperm- 
oil, prepared by Mr. Alfred H. Allen of Sheffield, Public Analyst 
for the West Riding of Yorkshire.

These results show that the closest similarity exists between 
genuine sperm-oil and the oil from the Bottlenose Whale. 
Their ordinary food consists of a bluish-white cuttle-fish, six inches 
long by three inches in circumference, and pointed towards the tail. 
The stomachs of the Whales that were examined contained nothing 
but their remains; and we never took one alongside without seeing 
some of them floating out of their mouths. 
They evidently have a great depth to go to find them, judging 
from the length of time that they remain away, and from the long 
heavy blasts they make on coming to the surface again. 
They are much infested with lice about the fins and in patches 
over their bodies. I send with this a piece of skin cut from the 
front of the head of a young female, which will serve to show the 
manner in which they adhere to the skin’. 
During the present season, in May and June, two hundred and 
three were killed; of these ninety-six were fuil grown males, fifty- 
six cows, and fifty-one younger males. 
From a cow a young male was cut out, measuring ten feet long by 
five feet six inches in circumference. ‘The length of the mother 
was twenty-nine feet. 
The heads of two males were measured round the eyes: one was

of a Hyperoodon captured in Portland Roads on the 2nd of October 1854, as
