Copying invention
been writing on this, and steep it in infusion of
galls: then take the paper you want to copy &
apply them to one another : rub them hard together,
which is most commodiously done in a common
rolling-press: the galled paper will receive
a black tinge from the ink of the paper
written on. Douglas & some more of them tried
the experiment at Alice's Coffee-house in
Westm-Hall a day or two ago. All they did
was to put the two papers together in a book
and stamp upon it with their feet. It succeeded
perfectly well. I have not yet learnt
the man's name — he has got or is going to
have a patent for it: the way he avails himself
of it, it is said is by selling the rolling
presses which he does at 12 guineas.
Anderson says you may have one for 10s
that will answer the purpose. He, I think
impregnates the paper with the galls: but
Anderson says he imagines the solution of
gr- vitriol might do as well. The paper to be
copied must be applied as soon as the ink is
well dry, they say: otherwise it may be
necessary to damp it. Lind tells me it is the invention
of Bolton of Birmingham .
Anderson's Ne4ws-paper
Anderson is going to set up a newspaper
here. It is to come out weekly, to contain
32 8vo pages, and to be sold for 4d.
He has completed his agreement with a
Bookseller who is to be the undertaker, &
wants nothing by a proper Printer. He
thinks he shall begin the first of July: It
will have the advantage of all the others in
point of intelligence relative to the serious &c
but I fear it will be inferior to them in point
of stile. Now, Sir, I do desire of yo0u that you
would collect every thing that you can there
< where you are and send him: everything I
mean except what might be traced up to you
and turned to your prejudice. I shall give
him for example your account of the execution
at Hamburgh. Your short account of Grassman's
process
