126 ANATOMY OF THE SPERM WHALE, 
Some of these lateral branches enter the common trunk 
in the direction of the milk passage —others in the con- 
trary direction, especially those nearest to the termina- 
tion of the trunk, in the middle. The trunk is large, and 
appears to serve as a reservoir for the milk, and termi- 
nates externally in a projection, which is the nipple. 
The lateral portion of the sulcus which encloses the 
nipple is composed of parts looser in texture than the 
common adipose membranes, which is probably to admit 
of the elongation or projection of the nipple. On the 
outside of this there is another small fissure, which I 
imagine is likewise intended to give greater facilities to 
the movements of all these parts. The milk is pro- 
bably very rich, for in that caught near Berkley, with its 
young one, the milk, which was tasted by Messrs. Jenner 
and Ludlow, surgeons at Sudbury, was rich like cow’s 
milk to which cream had been added.” 
The whales which Mr. J. Hunter had opportunities 
of examining, were of seven kinds, viz. : 
The spermaceti whale. The piked whale, 
The Greenland whale, The nar-whale, 
The bottle-nosed whale, Two grampusses, 
and several male and female porpoises.
