EME 
EMB 
thers sessile, sitting on the tips of the pe- 
tals; follicle round. There are four species. 
EMBRACERY, is an attempt to corrupt 
or influence a jury, or any way incline them to 
be more favourable to the one side than the 
other, by money, promises, letters, threats, 
or persuasions; whether the juror, on whom 
such attempt is made, give verdict or not, 
or whether the verdict given be true or 
false, which is punished by fine and impri- 
sonment; and the juror taking money, per- 
petual infamy, imprisonment for a year, and 
forfeiture of tenfold the value. 
EMBRASURE, in fortification, a hole 
or aperture in a parapet, through which the' 
cannon are pointed to tire into the moat or 
field. Embrasures are generally twelve feet 
distant from one another, every one of 
them being from six to seven feet wide with- 
out, and about three within : their height 
above the platform is three feet on that 
side towards the town, and a foot and a halt 
on the other side towards the field ; so that 
the muzzle may be sunk on occasion, and 
the piece brought to shoot low. 
EMBROCATION, in surgery, an exter- 
nal kind of remedy, which consists in an 
irrigation of the part affected with some 
proper liquor, as oils, spirits, £cc. by means 
of a woollen or linen cloth, or a spunge, dip- 
ped in the same. The use of embrocation 
is either to attenuate and dislodge some- 
thing obstructed underneath the skin, to 
ease pains, or to irritate the part into more 
warmth and a quicker sense of feeling. 
The pumping used in natural baths is pro- 
perly an embrocation. 
EMBRO IDERY, a work in gold, or silver, 
or silk thread, wrought by the needle upon 
cloth, stuff, or muslin, into various figures. 
In embroidering stuffs, the work is per- 
formed in a kind of loom, because the more 
the piece is stretched, the easier it is 
worked. As to muslin, they spread it upon 
a pattern ready designed ; and sometimes, 
before it is stretched upon the pattern, it 
is starched to make it more easy to handle. 
Embroidery on the loom is less tedious than 
the other, in which, while they work flow- 
ers, all the threads of the muslin, both 
lengthwise and breadthwise, must be conti- 
nually counted ; but on the other hand, this 
last is much richer in points, and suscepti- 
ble of greater variety. Cloths too much 
milled are scarce susceptible of this orna- 
ment, and in effect we seldom see them 
embroidered. The thinnest muslins are left 
for this purpose, and they are embroidered 
to the greatest perfection in Saxony; in 
other parts of Europe, however, they em- 
broider very prettily, and especially in 
France. 
There are several kinds of embroidery, 
as, 1. Embroidery on the stamp, where the 
figures are raised and rounded, having cot- 
ton or parchment put under them to sup- 
port them. 2. Low embroidery, where the 
gold and silver lie low upon the sketch, and 
are stitched with silk of the same colour. 
3. Guimped embroidery : this is performed 
either in gold or silver ; they first make a 
sketch upon the cloth, then put on cut vel- 
lum, and afterwards sew on the gold and 
silver with silk thread : in this kind of em- 
broidery they often put gold and silver 
cord, tinsel, and spangles. 4. Embroidery 
on both sides ; that which appears on both 
sides of the stuff. 5. Plain embroidery, 
wdiere the figures are flat and even, without 
cords, spangles, or other or naments. 
Embroidery, no foreign embroidery, 
on gold or silver brocade, is permitted to he 
imported into this kingdom on pain of being 
seized and burned, and a penalty of 100'. 
for' each piece. 
EMBRYO, in physiology, the first rudi- 
ments of an animal in the worn!), before 
the several ■ •'mbers are distinctly formed; 
after which period it is denominated afoetus.

EMERALD. This mineral comes chiefly 
from Peru; some specimens have been 
brought from Egypt. Dolomieu found it 
in the granite of Elba. Hitherto it has 
been found only crystallized. The primi- 
tive form of its crystals is a regular six-sided 
prism ; and the form of its integrant mole- 
cules is a triangular prism, whose sides are 
squares, and bases equilateral triangles. The 
most common variety of its crystals is the 
regular six-sided prism, sometimes with the 
edges of the prism, or of the bases, or the 
solid angles, or both wanting, and small 
faces in their place. 
Crystals short; lateral planes smooth, 
terminal planes rough ; colour emerald 
green of all intensities ; internal lustre be- 
tween 3 and 4 ; vitreous ; fracture small, 
imperfect, conchoidal, with a concealed 
foliated fracture, and fourfold cleavage ; 
fragments sharp-edged ; transparency 4 to 
2 ; causes double refraction ; scratches 
quartz with difficulty. Specific gravity from 
2.600 to ‘2.7755. 
The fossil here described is the occidental 
emerald, and appears from antique gems to 
have beer known in the earlier ages, though
