 in the Porpoise, Spermaceti, and large \\ hale i 

 Whale, and coarse in the Grampus and small 

 Whalebone Whale. In all of them it is I

which is composed of fibres without any

In this order of animals the internal fat is the 



fluid, and is nearly of the consistence of hog'g 

 lard; the external is the common train oil: but 

 the Spermaceti Whale differs from i '.her 



animal 1 have examined ; having ti kinds of 



fat just mentioned, and another which is totally 

 different, called spermac eti. This is found every 

 where in the body in small quantities, mixed with 

 the common fat, to \vhich it | \crysinall 



proportion; but in the head it is the u \CIM-, for 

 there the spermaceti is large in quantity compared 

 with the oil, although they arc mixid, as in other 

 parts of the body. As the spermaceti is found in 

 the largest quantity in the head, and in what 

 would appear on a slight view to be the cavity of 

 the skull, from a peculiarity of the .shape of that 

 bone, it has been imagined by some to be the 

 brain.
