^ H I S fpecies inhabites the ille of St. 
Kilda: makes its appearance there in 
November , and continues the whole 
year, except September and OClober ; it lays a 
large, white, and very brittle egg \ and the young 
are hatched the middle of June, No bird is of 
equal ufe to the iflanders as this : the Fulmar fup- 
plies them with oil for their lamps, down for their 
beds, a delicacy for their tables; a balm for their 
wounds, and a medicine for their diftempers. The 
whole genus of Petrels have a peculiar faculty 
of fpouting from their bills, to a confiderable dift- 
ance, a large quantity of pure oyl} which they 
do, by way of defence, into the face of any that 
attempts to take them : % fo that they are, for

this oil is fubfervient to the above-mentioned 
medical ufes. Martin tells us, it has been ufed in 
London and Fdenburgh with fuccefs, in Rheuma¬ 
tic cafes. 
The fize of this bird is reprefented in the plate. 
The noftrils are compofed of two large tubes, 
lodged in one iheath ; the head, neck, whole 
under fide of the body, and tail, are white 5 the 
back, and coverts of the wings afh-colored; the 
quil feathers dufky; the legs yellowifh. In lieu 
of a back toe, it has only a fort of fpur, or fharp 
ftrait nail. Thefe birds feed on the blubber or 
fat of whales, &c. which, being foon convertible 
into oil, fupplies them conftantly with means of 
defence 5 as well as provifion for their young, 
which they call up into their mouths.
