pearls. But as thefe anlficial pearls are not proof 
againft moifture, v/orkrnen have a method of lining 
the infides of glafs beads with the fluid, blowing 
in a little of it with a fmall pipe, and fhaking it 
about till it fixes all over the internal furface. 
This being done, they throw them into a bafket, 
and fiiake them together till they become quite 
dry; after which, in order to render them the 
more folid, they line them with wax. This is the 
genuine method of making the true French neck- 
laces; tlie manufafture of w^hich employs great 
numbers of that ingenious people. 
BLENNY, or BLENNIUS. A genus of fifli 
of the general order of acanthopterygii, according 
to the diftribution of Artedi ; and ot the jugulares 
in the Linnfean fyftem. The characters of this 
genus are, that the membrane of the gills has fix 
bones; that the fore-part of the head is very flop- 
ing; that the body is fmooth and flippery; that 
the teeth are fiender; and that the ventral fins 
generally confifl; of two united rays. 
Blenny, Crested. This fpecies is fometimes 
found on the fhores of the Britifh Ifies, and is com- 
monly about four or five inches long. On the 
head there is a fmall creft-like fin, which the fifii 
is capable of erefting or deprefling at plealure ; 
on the top of the head, between the eyes, there is 
a triangular prominence pointing backwards, and 
red about it's edges : the flvin at the angle of the 
upper jaw is loofe, and proje6ling; the dorlal fin 
extends from the hind part of the head almoft to 
the tail; the ventral fin is iinall; the vent is fitu- 
atcd under the ends of the pedoral fins; the body 
is fmooth and-flippery; and the colour is brown, 
and maculated. 
Blennv, Gattorucine. This curious fpecies 
is feven inches and a half long. The body is 
fnooth, and comprefi^ed on the fides ; the belly is 
a little prominent; and the vent is fituated as in 
the crefted Blenny. The teeth are fo extremely 
fiender and thick fet, that they appear almoft feta- 
ceous : between the eyes there is a flight deprefllon; 
and above each, exaclly on the fummit, there is a 
narrow loofe membrane, trifurcated at the top, the 
diftinguifliing mark of the fpecies. The pecto- 
ral fins, which are broad and rounded, confiil of 
fourteen rays, extending beyond the webs, and 
giving a icolloped appearance to the edges; the 
ventral fins are like thofe of others of the genus ; 
the dorfal fin confifts of fourteen ftrong fpiny rays, 
and nineteen foft rays, the lafi: of which are the 
highcfi-; the anal fin hath twenty-one rays, the 
ends in every fin extending beyond their webs; 
and the tail, which is rounded at the extremity, 
confifts of twelve rays, divided towards their ex- 
tremities. Tiie colour of this fpecies is duflcy, 
marked acrofs with wavy lines; the belly is of a 
light cinereous hue; and the lower part of the pec- 
toral fins, as VytII as the extremities of the ventral 
fins, are of an orange colour. 
Blenny, Smooth. This very a£live and viva- 
cious fpecies frequents the rocky coafts of Angle- 
fea; and, by the alTiftance of it's ventral fins, creeps 
up between the ftones with great facility after the 
ebb has left them. It fecms to fubfift on fhells and 
fmall crabs ; and is fo very tenacious of life, that 
it will live near a day out of the water. The ge- 
neral length of this fiik is about five inches; the 
head is large, and fioping fuddenly to the mouth; 
the irides are red ; the teeth, which are fiender, 
fliarp, and clofe fct, confift of twenty-four in the 
fuperior, and nineteen in the inferior j aw ; the pec- 
toral fins are broad and rounded, and compofed of 
thi rteen rays ; and the ventral fins of no more than 
two thick rays, fepg,rated near the ends : the dor- 
fal fin confifts of thirty-two foft rays, and reaches 
from the hind-part of the head almoft to the extre- 
mity of the tail. The vent is placed in the middle 
of the body ; the anal fin extends almoft to the tail,- 
and confifts of nineteen rays, tipped with white ; 
and the tail is I'ounded at the extremity, and com- 
pofed of twelve branched rays. The colour of this 
fpecies varies confiderably: in fome it is quite 
black ; in others, a deep olive, delightfully mar-' 
bled with a ftill deeper colour; and others are fpot- 
ted with white, fometimes difpofed in rows above 
and beneath the lateral line. 
Blenny, Spotted. This fifli is about fix in- 
ches long. The fides are extremely comprefi^ed, 
and very thin ; the head and mouth are iiiiall, the 
laft pointing upwards, and the lower jaw fioping 
confiderably tov/ards the throat: the teeth are frj:;a]l; 
and the irides are of a whitifli colour. The pecto- 
ral fins are rounded, and yellowifii ; and, inftead of 
ventral fins, it has tw^o minute fpines; the aovfuY 
fin confifts of feventy-eight fhort fpiny rays, run- 
ning almoft the entire length of the back : on the 
top of the back there are eleven round fpots, which' 
reach the lower half of the dorfal fin; thele Ipots are 
black, and half encircled with white. The vent is 
placed in the middle of the body ; and tlie anal fin 
extends from it almoft to tiie tail. The back and 
fides are of a deep olive colour; the belly is wliitifii^ 
and the tail is of a yellow hue, and rounded at the 
extremity. This fpecies likewife frequents the coafts 
of Anglefea, and is ufed as a bait for larger filh. 
Blenny, Viviparous. This remarkable fpe- 
cies was firft diicovered by Sohonevelde, and after- 
wards found by that ingenious naturalift. Sir Ro- 
bert Sibbald, on thx coafts of Scotland. Thefe fifii 
generally bring forth two or three hundred young 
at a time. Their feafon of parturition is very ear- 
ly in the fpring ; and before inidftimmer they quit 
the bays and fliores, and retire into the deep. Their 
flefli, which is very coarfi;, is ufed only by the 
poor, 
Blennics are common in the River Eflc, as well 
as at Whitby in Yorkfhire, and fome other parts 
of England. TJiey are fometimes caught of the 
length of a foot. Their bodies are fiender; their 
fkins are imooth and flippery; their dorfal fi.ns 
commence iuit behind their heads, and unite Vvdth 
thofe of their tails; their pectoral fins are founded;, 
their ventral fins confift of no more than foiir ihort 
rays each; their anal fins extend far, and unite 
with their tails ; and their tails them/elves are round- 
ed. The tips of their tongues, their chins, tliroats, 
and anal fins, are of a fine yellow colour; and their 
dorfal fins, backs, and fides, are of a yellow] fii 
brown, ftained v/ith dufky lines and fpots. 
BUCEA. A fm.all fifir of the harengifcrni 
kind, commonly caught in the Germ^an and other 
feas; and fuppofed to be the fame with the Englifii 
fprat, which fome naturalifts regard as tlie young- 
of the herring. 
Blicea is likewife the nam.e of a frcfii-water filht 
of the malacoft'om.ous or leather-mouti'ied kind; 
fecmingiy the fame with the more'common kind of 
circafiius. 
Blicea is alfo the name of an Eaft Indian fifi?, 
which might more properly be called tlie harengus 
minor Indicus, or leffer Indian herring. It is ha- 
rengiform in moft particulars, except that it is fom.e- 
what more deprefted, and thinner. It is exactly of
