ter, rub a clean sheet of paper on one side 
w ith this mixture, so that it may bear a slight 
touch of the dinger without leaving the pa- 
per ; then laying the coloured side of this 
.paper upon a clean sheet, lay your print 
upon the other side of the coloured paper ; 
and then trace every line you think proper, 
as already directed in tracing a draught with 
fixed ink : but be sure to pin the three pa- 
pers together at the corners, to prevent 
tii- ir slipping, which would inevitably spoil 
your work. This impression made by tra- 
cing will hold without rubbing or pressing the 
papers. The quills of a swallow, after they 
-are thoroughly dry, are very good for tra- 
cing. 
By mixing carmine with some fresh butter, 
and colouring a paper with it in the same 
manner, you will obtain a more beautiful 
colour; and bv colouring a paper in like 
manner with blue bice and butter, you may 
have the drawing blue. 
To take (he natural or lively shape of any 
herb or tree . — First take the leaf you would 
copy, and gently rub the veins on the back 
side of it witli a piece of ivory, or some such- 
like matter, so as to bruise them a little ; 
afterwards wet the same side gently with lin- 
seed-oil, and then press it hard upon a piece 
of white paper, and you shall have the per- 
fect. figure of the leaf, with every vein in it 
justly expressed : this impression being af- 
terwards coloured will seem truly natural, 
and may be useful to such as would remem- 
ber plants. 
Another may of painting the leaves of 
plants, so that the impression shall appear as 
black as if it had been done in a printing- 
press, is as follows . — When the leaf is dry, 
take such a ball as the pressmen use for 
blacking the types, and rubbing it equally 
ever with printer’s ink, strike it gently four 
or live times on the back of the leaf, till all 
the veins are blacked with the ink ; then 
laying the leaf on a flat board or the like, 
with the back side upwards, clap a piece of 
white paper well moistened on the leaf ; and 
pressing it pretty hard, but not so as to bruise 
the fibres, you shall have a fine impression. 
But this may be done to still greater ad- 
vantage by means of a piece of w r ood in the 
form of a cylinder, about a foot long, and 
an inch and a half diameter, the middle part 
about six or eight inches long, being covered 
with a woollen cloth rolled three or four 
times round it. With this cylinder roll the 
paper over the leaf four or live times back- 
wards and forwards, and you will have a cu- 
rious impression. 
But where printers ink is not conveniently 
come at, the following method may be made 
use of: Rub the back of the leaf, as before 
directed, with burnt linseed-oil: then, strew- 
ing some powder of black lead, or, for want 
of that, some charcoal or small-coal dust, or 
the powder of burnt cork, upon a smooth 
board, so as equally to cover it, stroke the 
powder gently over ; and oiling the back 
side of the leaf, clap it upon the board; then 
laying the white paper upon the back of the 
leaf, press or roll it as before. 
If none of these ingredients are conve- 
niently had, take vermilion, and mixing it 
with fr.esh butter to the consistence of 
printer’s ink, coyer your printing-ball with 
£> II I 
it : daub it over the back of the leaf, and 
take your impression as before. - 
Where vermilion is used, bice may also be 
made use of, either with butter or oil, by 
grinding blue bice with some burnt linseed- 
011, and using it as before: thus you may 
have a tine red or blue ink, proper for im- 
pressions of this sort ; but the blue is prefer- 
able in colouring leaves, because it is an 
agreeable colour for the green sort. 
Jt may be observed, that the reason why 
the back of the leaf is the proper side to make 
the impression from, is because the ribs or 
vessels rise on that side above the fleshy part 
of it; and therefore being coloured with any 
of those inks, they are the fittest to give an 
impression ; whereas, in the foreside of the 
leaf, the fleshy parts rise, and these fine 
fibres are sunk between them. 
DR FIN, in the military art, a trench made 
to draw the water out of a moat, which is 
afterwards filled with hurdles and earth, or 
with fascines, or bundles of rushes and 
planks, to facilitate the passage over the 
mud. 
DRESSING of ores, the breaking and 
powdering them in the stamping-mill, and 
afterwards washing them in a wooden trough. 
Dressing. See Surgery. 
DRIFT of the forest, is an exact view and 
examination taken at certain times to know 
what beasts are there; in order that none 
may come on the forest but . such as have 
right, and that the forest be not overcharged 
with beasts. 
Drift, in mining, a passage cut out under 
the earth, betwixt shaft and shaft, or turn and 
turn; or a passage or way wrought under the 
earth, to the end of a meer of ground, or part 
of a meer. 
Drift, in navigation, the angle which 
the line of a ship’s motion makes With the 
nearest meridian, when she drives with her side 
to the wind and waves, and is not governed by 
the power of the helm ; it also implies the dis- 
tance which the ship drives on that line, A 
ship’s way is only called drift, in a storm ; 
and then it blows so vehemently as to prevent 
her from carrying any sail, or at least restrains 
her to such a portion of sail as may be neces- 
sary to keep her sufficiently inclined to one 
side, that she may not he dismasted by the vi- 
olent labouring produced by the turbulence 
of the sea. 
Drift-sail, a sail used under water, veer- 
ed out right ahead by sheets, as other sails 
are. It serves to keep the ship’s head right 
upon the sea in a storm, and to hinder her 
driving too fast in a current. 
DRILL, in mechanics, a small instrument 
for making such holes as punches will not 
conveniently serve for. Drills are of va- 
rious sizes, and are chiefly used by smiths, 
turners, carpenters, and coopers. 
Drill, or drill-box, a name given to an 
instrument for sowing land in the new method 
of horse-hoeing husbandry. 
DRiLL-wzrittg, a method of sowing grain 
or seed of any kind, so that it may all be at 
a proper depth in the earth, which is neces- 
sary to its producing healthful and vigorous 
plants. For this purpose a variety of drill- 
ploughs have been invented and recommend- 
ed ; but partly from the expence attending 
the purchase, partly from the complication 
of their structure, and partly from the attach: 
mrnt of the illiterate farmer to long habits, 
these excellent schemes for diminishing labour- 
have not received that share of encourage- 
ment to which they seem entitled. 
DRIVING, in the sea-language, is said 
of a ship when an anchor being let fall will not 
hold her fast, nor prevent her sailing away 
with the tide or wind. The best help iu this 
case is to let fall more anchors, or to veer out 
more cable ; for the more cable she has out, 
the safer she rides. YV hen a ship is a-hull or 
a-try, they say she drives to leeward. 
1) KOI 1’, jus, signifies right or law, of 
which some distinguish six kinds: 1. Jus 
rccuperandi, right of recovery. 2. Jus en- 
trandi, right of entering. 3*. Jus habendi, 
right of having. 4. Jus retinendi, right of 
retaining. 5. Jus percipiendi, right of re- 
ceiving. 6. Jus possktendi, right of pos- 
sessing. 
Droit is also the highest of all real writs; 
and takes its name of a writ of right, from 
the greatest regard being shown to it, and as 
it has the most assured and final judgment. 
There are several sorts of these writs used in, 
our law, as droit de avowson, droit de dower, 
droit de. garde, droit patent, droit rationabili 
parte, and droit sur disclaimer. 
DROMEDARV, dromedarins, a large 
animal of the camel kind, bee Camelus. 
DlvON E, in the history of insects, a kind 
of bee, larger than the common working or 
honeybees. See An s. 
DROPS, in meteorology, small spherical 
bodies which the particles of fluids sponta- 
neously form themselves into, when let fall 
from any height. This spherical figure, the 
Newtonian philosophers demonstrate to 
be the effect of corpuscular attraction; for 
considering that the attractive force of one 
single particle of a fluid is equally exerted to 
an equal distance, it must follow that other 
fluid particles are on every side drawn to it, 
and will therefore take their places at an equal 
distance from it, and consequently form a 
round superficies. See Attraction, and 
Meteorology. 
DROPS V , in medicine, an unnatural col- 
lection ofwatry humours in any part of the 
body. See Medicine. 
DROSERA, or sun-dew, a genus of the 
pentagynia order, in the pemandria class, 
of plants, and in the natural method rank- 
ing under the fourteenth order, gruinalos. 
T be calyx is quinquelid, the petals five ; the 
capsule unilocular, and quinquevalved at top ; 
the seeds very numerous. There are nine 
species, two of which grow naturally in boggy 
places in many parts ol the kingdom. They 
seem to receive the name of sun-dew 
from a very striking circumstance in their ap- 
pearance. The leaves, which are circular, 
are fringed witli hairs supporting small drops 
or globules of a pellucid liquor like dew, 
which continue even in the hottest part of 
the day and in the fullest exposure to the sun. 
The whole plant is acrid, and sufficiently 
caustic to erode the skin : but some ladies 
mix the juice with milk, and apply it to 
remove freckles. The juice that exsudes 
from it umnixed, will destroy warts and corns. 
The plant has the same effect upon milk' as 
the common butterwort; and like that too 
is supposed to occasion the rot in sheep. 
DROWNING, signifies the extinction 
of life by immersion in. water. In some.
