ber, our Seamen call the Blubber : It was firm, full of fibres, 
and in this fmall fi(h, of an inch thicknefsj encompaffing and 
enclofingthe whole body, back, belly and fides*. The ufe 
whereof 1 conceive to be, to keep the cold water at a di^

touch hot 5 in a degree not much iiifcriour to that of Qua- 
drupedsj and therefore by immediate contact: of the water

the bloud from evaporating 5 by that means alfo preferviug

the fi(h , whi^h would otherwife be too heavy Co move and

great length, bymeature48 foot, without any difference or 
diftindtion of great and fmall; neither was there any Blind*
