if the connexion is long, it would interfere with the aft of 
refpiration, as in any other pofition the upper furface of the 
heads of both could not be at the furface of the water at the 
fame time. However, as in the parts of generation they moll 
refemble thofe of the ruminating kind, it is poffible they may 
likewife refemble them in the duration of the aft of copula- 
tion ; for, I believe, all the ruminants are quick in this aft. 
Of their uterine geftation I as yet know nothing ; but it is 
very probable, that they have only a fmgle young one at a time, 
there being only two nipples. Thisfeemed to be the cafe with 
the Bottle- nole Whale, caught near Berkeley, which had been 
feen for fome days with one young one following it, and they 
Were both caught together. 
The glands for the fecretion of milk are two; one on each 
fide of the middle line of the belly at its lower part. The 
pofterior ends, frpm which go out the nipples, are on each 
fide of the opening of the vagina, in fmall fulci. They are 
flat bodies lying between the external layer of fat and abdo- 
minal mufcles, and are of conliderable length, but only one- 
fourth of that in breadth. They are thin, that they may not 
vary the external fhape of the animal, and have a principal 
duft, running in the middle through the whole length of the 
gland, and colleftingthe fmaller lateral dufts, which are made up 
of thofe {till Imaller. Some of thele lateral branches enter 
the common trunk in the direftion of the milk’s palfage, others 
in the contrary direftion, efpecially thofe neareft to the termi- 
nation of the trunk in the nipple. The trunk is large, and 
appears to ferve as a refervoir to the milk, and terminates exter- 
nally in a projeftion, . which is the nipple. The lateral por- 
tions of the fulcus which indoles the nipple, are compofed of 
parts loofer in texture than the common adipofe membrane, 
which is probably to admit of the elongation or projeftion of
