ginal and the paper being thus marked out, obferve what is con-
tained within each fquare of the piece you would copy, as an head,
an arm, a hand, and fo on, and where each is placed ; all which
you muft punctually follow on your paper; and, having thus ob-
tained the fituation of each part, join the whole together. After
this manner you may enlarge, as well as diminifh any piece you
pleafe, only by making the fquares on the paper larger than thofe
on the original, or fmaller, obferving always that they are the
fame in number.
To copy a picture, or any thing elfe of the fame fize, take
oiled paper dried, or gold-beaters fkin ; either of thefe we lay
upon the piece, through which you may fee the ftrokes, which
trace out uTith a crayon or pencil: Then take it off, and make
it fa ft to vellum or paper, and, holding it up to the light, trace
out what has been copied upon the oiled paper or fkin, either
with a crayon or a diver pin.
By the help of a window, or a glafs held up to the light, are
copied all forts of prints, defigns, and other pieces, upon paper
or vellum, by fixing them to the paper or vellum you intend to
draw upon. This is an eafy and good contrivance for copying of
the fame fize.
If you would make the piece look a contrary way, turn the
printed or drawn fide 01 the original towards the glafs, and faften
the paper or vellum to the backfide of it.
There is alfo a good way to take an exact copy of a picture
which is in oil colours : Which is, with a pencil and fome lake
mixed up with oil, to trace out all the principal ftrokes of the
picture, and applying thereto a paper of the fame fize ; then pafs
your hand over it, and the ftrokes of the lake will take the pa-
per, and appear thereon, which you may calk as before. Be
mindful to clean the picture with the crumb of bread before the
lake dries.
Alfo, to the fame end, ufe coal-ouft, contained in a piece of
fine linen, wherewith pounce the piece you would copy, having
firft pricked the principal ftrokes of it, and fattened a piece of
vellum or paper to the wrong fide of it.
But, for one who has no hand at drawing, there is a more
fure and eafy way than any before-mentioned, by the help ot a
mathematical inftrument, or compafs, as it is iometimes called,
which is commonly compofed of ten pieces ot wood like rulers,
about the fixth of an inch thick, and half an inch broad ; as for
their length, it may be a foot, more or lefs, according to the fize
of the piece you would copy. But, that you may not miflake,
here follows a reprefentation of it. See plate VII, fig. i.
