in proportion to the wide fpreading of their horns ; fo that we 
may iafely conclude, that Moo/es were formerly as frequent in 
Ireland^ as they are ftill in the nxDrihern parts of the JVeJt-LidieSy 
Ne-iv-Efiglarid, Virginia, Maryland, and Canada. 
There are leveral things in which Ireland and the Weft- 
Indies do partake in common 5 for as on the coaft of New- 
England, and the illand 'Bermudas confiderable quantities of 
ambergreal'e are gathered, fo on the weftern coaft of Ireland, 
along the counties of Sligo, A'layo, Kerry, and the ifles of 
Arran, they frequently meet with large parcels of that precious 
fubftance, io highly valued for its perfume 5 near Sligo there 
was found one piece, that weighed 5 2 ounces ; on the outfide 
it was of a clofe compact fubftance, blackifh and fhining, 
like pitch ; but when it was cut, the infide was more porous, 
and Ibmething of a yellowifh colour, not fo grey, cloie, and 
fmooth as the cleaneft and beft fort of amber, but like it, 
Ipeckled with whitiflT grains, and of a moft fragrant fcent. 
Nor is that fpecies of whales, that are often taken in Ke'vc- 
England,^ and which yield the true Sperma Ceti, a ftranger to 
tl\at coaft of Ireland, that regards America, and which we 
may call the Cetus dentatus, from its large, folid, white teeth, 
fixed only in the lower jaw, to diftingui/h it from that fpecies, 
which yields the whale-bone, juftly denominated Myfticetus 
by Arijhtle, from its bearded, horny Laminae in the roof of 
the mouth. What fort of fubftance Sperma Ceti is, and in 
what part of the whale it is found, naturalifts and phyficians 
are not agreed in- but Dr. Molyneux found it to be nothing 
otlier than part of the oil, or liquid fat of this particular Ibrt 
of whale; which oil, at firft, when confufed and mixed, fhews 
like a whitifl:i liquor, of the coniiftence and colour of whey ; 
but laid by in veiTels to fettle, its parts by degrees feparatc 
that which is lighter, and fwiming a-top, becomes a clear oil, 
} ellucid like water, anfwering all "the ufes of common trains 
oil,vvhich is got out of the blubber of other whales; that 
which fubfidcs, becaule it is heavier and of a cloier confiftence, 
candies together at the bottom, and is what is Md for Sperma 
Ceti,^ the blanching and refining of which is troublelbme, and 
requires no Imall art, time, and charge; the fat of the whole 
body affords it, but that of the head yields the gveateft quantity, 
and pureft Sperma Ceti.
