dently a fpecies of the cow-kind, and probably dif- 
fers from the common breed rather by local than 
natural caufeSi The Bonafus is a very thick and 
buiky creature, and furniflied with a mane like that 
of a horfe. It is fomewhat larger than our bull ; 
the horns do not exceed a fpan in length, and are 
fo turned as to be incapable of inflifting a wound j 
the noftrils are wide ; and the cars are long and 
broad. The colour of the animal is a deep tawny, 
except that the forehead and the breaft are white ; 
and the mane is of a darker colour than the reft of 
the body. Like others of this kind, it has no teeth 
in the upper jaw before; the tail is fliort in pro- 
portion to the reft of the body; and the legs are 
covered with hair. It bellows loudly, like an ox ; 
and, when purfued, does not attempt to defend it- 
felf with it's horns, but kicks, and difcharges it's 
dung againft it's adverfary, which is pretended to 
be of a hot andcorrofive nature onfuch occafions, 
diough notfo at other times; a circumftance fcarce- 
iy credible, fays Ray, if there were not inftances of 
other animals pofieffing a fimilar faculty* 
BONITO. This fifli, to which fome naturalifts 
give the name of bonettoe, is about three feet long, 
and two in circumference. It is often feen in com- 
pany with the albicorcj a fiflT. nearly refembling-it- 
felf, and frequently miftaken for the fame. The 
Bonito has a fharp head; a fmall mouth; large 
gills ; full filvery eyes ; and a tail like a half moon. 
It has no fcales, except on the middle of the fides, 
where a line of a gold colour runs from the 
head to the tail. It is greenifh on the back and 
fides ; but it's belly fhines like filver. It has feven 
fins; two on the back, two at the gills, a pair on 
the belly iuft below the gills, and one on the mid- 
dle of the belly oppofite the iargeft- on the back *. 
from the laft on the back proceeds one very fmall 
and narrow, reaching to the tail; and another ex- 
tends from the laft on the belly to the tail in like 
manner. 
. BONT-VISCH. A Dutch appellation for an 
•Eaft Indian fifli, which feems to approach to the 
nature of the European turdus, except that it is de- 
ftitute of fcales. 
BOOBY, COMMON. This bird is generally 
found about the Weft Indian ftiores, and in feveral 
parts of the Eaft. The Jamaica Booby is defcribed 
by Sir Hans Sloane under the title of avis fufca, 
anferi baffano affinis. It feeds upon fifti, diving 
under water after them; but is often robbed of 
it's prey by the voracious albatrofs or man-of- 
war bird: and the frequent contefts between 
thefe two birds are extremely diverting; the for- 
mer fticvv^ing as great relu6lance to part with it's 
prey, as the latter is refolute in plundering the for- 
mer. This fpecies of Booby is fliaped like a ra- 
ven ; the upper parts are of a greenilli brown ; the 
belly is white ; and the feet refemble thofe of the 
duck tribe. 
Booby of New Guinea. This fpecies, which 
was firft defcribed by Sonnerat in his Voyage to 
New Guinea, is about three feet long. The head, 
the neck, and the fore part and top of the breaft, are 
black; the back is of a blueifligrey; the belly and 
legs are covered with white feathers ; the wings are 
ftreaked with longitudinal lines alternately black, 
andofa greyilhwhite colour; and the feathers which 
cover them are lliort, ferrated, and arranged like 
fcales. On each fide of the head rifes a bar, which 
is large and rounded at it's beginning, and of a deep 
yellow colour ; after which it grows narrow, and 
more pale, till it approaches the belly, when it 
fpreacts itfelf over all it's upper part. The feet are 
black, and fcaly; and the bill is long, rounded, 
prominent, and incurvated at it's extremity; of a 
black colour two-thirds of it's length from the bafe, 
and ycllowifh from thence to the point. 
Booby, White-Collared. This bird is like- 
wife a native of New Guinea; and is about a foot 
and a half in length. The head, throat, hind part 
of the neck, fides, back, wings, and tail, are black ; 
the fore part of the neck, the breaft, belly, and 
legs, are white; and feathers of the fame colour 
form a femicircle round the lower part of the neck, 
which being contraftedvv'ith the furrounding black, 
has a very pleafing effect. The eye is furrounded 
with a naked memibrane,of a blood-red colour; and 
the bill, the feet, and the irides, are black. 
Booby, Papou. This fpecies, according to 
Sonnerat, is about two feet long. The head and 
neck are gi-eyilli inclining to black; on the top of 
the head behind, there is a femicircular white bar ; 
the back and tail are black ; the wings are black in 
the middle, the exterior borders being grey, and the 
interior white ; the breaft, belly, and legs, are white ; 
the irides are yellow; and the feet and bill are of a 
reddiili hue. 
Tiiis bird is a native of New Guinea, and re- 
ceives it's name from the Papoos, a people inhabit- 
ing that and the neighbouring ifles; who, being 
feldom vifited by navigators, are of courfe very 
little known. 
BOOK- WORM. An infe-fl of the moth-kind, 
which is bred from eggs depofited in books about 
the month of Auguft, and afterwards becomes a 
fly. It pretty nearly refembles the mite, or blatta, 
found in corn; and when the time of it's transfor- 
mation approaches, it eats it's way through, in or- 
der to breathe a freer air. 
Various expedients have been adopted for coun- 
terafting the depredations of this noxious animal ; 
but the bcft, and indeed the only fecurity to books, 
is derived from mineral falts, to which every fpe- 
cies of infefts ftiews a ftrong averfion. For this 
purpofe, book-binders ought to mix the fait known 
by the name of arcanum duplicatum, alum, and vi- 
triol, with the pafte ufed in binding; and by this 
precaution books may be perfeftly freed from all 
the damages occafioned by this mifchievous infe£l. / 
Mr. Prediger, in his Inftruftions to German 
Book-binders, printed atLeipfic in 1741, recom- 
mends the making pafte of ftarch inftead of flour ; 
and the powdering flightly the books, their covers, 
and the flielves on which they ftand, with a mix- 
ture of pulverized allum and fine pepper; and is 
alfo of opinion that, in the months of March, July, 
and September, books fhould be rubbed with a 
woollen cloth fteeped in powdered allum. 
BOOPS. A fmall fifli commonly caught in 
the Mediterranean fea, about five inches in length, 
and remarkable for the largenefs of it's eyes. It 
is of a rounded fhape, has large fcales, and is 
deemed a fpecies of the fparus. But, befides this 
common Boops, there are two other varieties : the 
one, commonly called bouge-ravel, is nearly about 
the fize of the Boops ; and the other kind is fmall, 
being no more than three inches long, and defti- 
tute of fcales. It's mouth is fmiall; and it's eyes 
are extremely large. 
Boops is alfo a name fometimes ufed to exprefs 
a fpecies of whale. 
BOOR-WORM. A name given by fome 
zoologifts to the folen lignorum, a fea- worm which 
perforates the bottoms of Ihips. 
BORBOTHA.
