i ll. It is to be obferved, that this fpecies has hut one fpout 
(fijlutaj, I his Ipout is not, as hath been generally hitherto 
aider ted, in the neck f cervix ) of the fidi, hut in its front, and 
on the very edge of the head, bending obliquely on the left 
fide, lb that whenever he fpouts it is. always on that fide only. 
2dly. It is alfo remarkable, that the female of this whale 
has a power of drawing back its breads after it has fuckled 
the call, fo that it hardly appears to have any prominence on 
the belly, whereas when it fuckles they hang out very long. 
3dlv. It is not true, though it has hitherto been averted, that 
the iubftance which we fo abfurdly name Spermaceti, and which 
perhaps might with much greater propriety be called Sevum 
Phyfeteris, is found in the ventricles of the brain, and in the 
cavity of the fpinal marrow of the Phyfeter Macrocephalus. 
This fat fubdance, which is nothing but a kind of diet, un- 
doubtedly formed for fome particular purpofe of that whale, is 
.contained in a peculiar bony triangular cavity or trunk, which 
is lodged near the brain, and occupies nearly the whole upper 
part of the head. This trunk has no communication with the 
brain, hut is entirely feparated from it by its bony laminas. 
The brain, as in all other tidies, is very dnall in comparifon 
with the iize of the whale, and lies directly behind the eyes. 
In order to know whether the trunk in which the fperma- 
ceti is lodged had any connection with the brain of the whale, 
one of the above-mentioned gentlemen had the curiodty to 
lance that trunk, which in its upper part is only covered 
with the fkin, he found the whale not in the lead affeCted by 
this, but on the brain being lanced, the dune whale died im- 
mediate! v.
