GLU GLU 
more than in the day-time. During it's mofl lu- 
cid periods, it will fometimes fuddenly turn it's 
body round, and then the light will appear con- 
fined to a Ipace not larger than the head of a pin ; 
but, on being touched, it will immediately extend 
itfelf, and the light will become as large and bright 
as before. 
This infeft, taken in grofs, is ufed in medicine, 
and thought to be lerviceable in the ftone: and 
Cardan afcribes to it an anodyne virtue. 
Glow-Worm, Winged. This infeft has been 
well defcribed by Aldrovandus, who aflerts that it 
lays eggs which are hatched into fmall Worms; 
and that thefe in time become flies, after under- 
going the ufual transformations. Mouffett and 
Bartholine defcribe this animal nearly in the fame 
manner; but they allow only the male to have 
wings; while Scaliger, who contraditls this opi- 
nion, tells us that he has caught both males and 
females winged in the a£l of generation. This 
feems to be an evident proof that both fexes are 
winged: neverthelefs, thofe who have quoted this 
paffage, feem unconvinced of the truth of the af- 
fertion. Waller, however, who gives an account 
of thefe flies in the Philofophical Tranfa6lions, ob- 
ferved them in the fame manner, in the aft of co- 
pulation, both winged, and with no other differ- 
ence between them except tliat the female was the 
largeft of the two; a common cafe with refpecl to 
many other infefts. 
During the warmer months, this creature is 
fometimes caught in houfes, flying towards the 
flame of a candle; and, when examined in the 
dark, it appears to be partially luminous. Before 
it is furnifhed with wings, it is frequently found in 
the fhape of the common Glow- Worm; and then 
it always emits a kind of lambent flame. Both 
the male and the female, in their winged ftate, 
fhine during the fummer months; and their light 
is fometimes fo vivid, that it is perceptible even 
when there is a candle in the room. It's vibra- 
tions are irregular, and it's colour is grecnifli. 
The luminous parts confift of two fmall fpecks 
under the tail, in which the light continues for 
fome time after the tail is cut off", but gradually 
expires. The ufe of this light feems to be that 
of direfting the animal in it's courfe, and aflifting 
it in catching it's prey; to which purpofes it ap- 
pears admirably placed, the tail being eaflly bent 
under the belly, and then the light is thrown full 
on any furrounding objeft: this light the creature 
can conceal at pleafure, and by that means fre- 
quently efcapes when purfued by it's enemies. 
The Winged Glow-Worm, which is of the bee- 
tle kind, is of a brown and dulky colour : it is fur- 
niflied with hard or flielly wings, like other bee- 
tles ; and, v/hen thefe are expanded, a pair of very 
large membranaceous ones is difclofed to view. 
The head is covered with a fort of fhield; and 
under it the eyes are placed, which are black, 
large, and moveable; fo that the creature can oc- 
caflonally thrufl: them forwards: there are two 
hairy antennae; and the legs are^ like thofe of the 
common fly, hard, flielly, and hairy. 
GLUTTON; the Muftela Gulo of Linnsus. 
No precife defcription of this quadruped has hi- 
therto come under our obfervation; fome authors 
comparing it to the badger, others to the fox, fome 
to the bear, and others to the hyfena. Linnaeus 
ranks it among weafels, from- the fimilitude of 
their teeth; though the length of it's body, the 
iliortnefs of it's legs^ the foftnefs of it's fur^ it's 
difagreeable fcent, and it's infatiable appetite, 
feem to form fcronger lines of affinity between 
thefe animals. Klein, who defcribed a creature of 
this kind brought alive from Siberia, afllires us, 
that it was about three feet long, and one foot and 
a half high. On ccmiparing thefe dimenfions with 
thofe of the weafettribe, we fhall find that they ap- 
proach more nearly to the clafs iuft mentioned 
than any other. In the conformation of it's nofe, 
ears, teeth, and long bufliy tail, the Glutton en- 
tirely refembles theweafel; and, as to it's fuperior 
thicknefs and corpulence, they very naturally arife 
from it's infatiable voracity, which is fo remarka- 
ble, that from that circumfl:ance the animal re- 
ceives it's name. 
The Glutton is found in the northern parts of 
Europe and Siberia, as well as in thofe of Ame- 
rica, where it is called the carcajou. It's body is 
long and thick; it's legs are fhort; along the back 
it is of a black colour, but it's fides are a reddifli 
brown. It's fur is held in the higheft eflimation 
on account of it's foftnefs and beautiful glofs; it's 
tail is pretty long and bufny; it's legs and claws 
are better adapted for climbing trees than running 
along the ground; and, coniequentiy, it catches 
it's prey rather by furprize than purfuit. 
Indeed, fcarcely any of the long-bodied animals 
trufl to their fpeed: knowing their own incapacity 
to overtake their prey through celerity, they either 
creep upon it in it's retreats, or lie in ambufh, and 
feize it with a bound. The Glutton, from the 
conformation of it's le.o;s and the length of it's 
body, mufl; necefiarily be extremely flow; and, 
coniequentiy, it's only refource confifts in taking 
it's prey by furprize. Ail the reft of the weafel 
kind, from the fmallnefs of their fize, are better 
adapted for a life of infidious rapine than this; they 
are qualified to purfue their prey to it's retreats; 
they can lurk unfeen among the branches of trees, 
and hide themfelves v/ith facility under the leaves. 
But the fize of the Glutton prevents it from gain- 
ing admiffion where other anim.ais can retire; and, 
for the fime reafon, it with more difficulty lurks 
unfeen : hence, it's only refource is that of climbing 
a tree, v/hich it tffe6ls with eafe; and there it waits 
with patience till fome large animal panes under- 
neath, on which it fuddenly darts v/ith unerring 
aim, and leldom fails to conquer. 
In North America, this voracious creature is 
frequently feen lurking among the thick branches 
of trees, purpofely to furprize the deer, with which 
the extenfive forefts of that' quarter of the globe 
abound. Endued with a degree of patience equal 
to it's rapacity, the Glutton fingles out fuch trees 
as are marl^ed by the teeth or antlers of the deer; 
and fometimes watches, in filent expeftation, for 
feveral days together, ir it finds that thefe ani- 
mals either cautioufly avoid the place, or have 
forfaken that part Oi" the country, it then defcends 
v/ith relu6lance, purfues the beaver to it's retreat, 
or even commits itielf to the liquid element in 
quefl; of fifhes. But fhould it happen that, by long 
attention, and keeping clofe, at laft the elk or rein- 
deer fliould fall into the ambufcade, the famifiied 
Glutton darts down upon the haplefs animal, and 
flicks it's claws between it's fhouiders, where they 
remain unalterably fixed. In vain does the large, 
but timid viftim, encreafe it's fpeed, or threaten 
with it's branching horns ; the Glutton remains ob- 
ftinately in pofllillon of it's prize, eats through 
the neck, and at lafl: rends the large blood- veffels 
which are fituaied in that part.
