5eo"sOfbO. 4uC 1c6uIuk TOOTH is 1uTulSu-
ed with supply of books, mostly of
the kind prohibited by the Russian
Government. and printed in Leipzig,
Berlin, and Geneva. To these must be
added the leading revolutionary peri
odicals and newspapers, printed in and
out OF Russia. The majority Of the
students follow the courses Of medicine
at the Ecole de Medicine. and some
have distinguished themselves by pass
ling their examinations with flying
colors. When, however, they unite on
their own ground, politics are the order
of the day; and, without asserting that
the members of the Russian colony arc
all rabid Nihilists, it cannot be denied
that the antecedents of most of them
would hardly bear inspection from a
Russian point of view The greater
number have been obliged to "leave
their country for their country's good
without regular passports; but to say
that they are all enemies of the Rus
sian Government, or that their library
is the headquarters of the Russian So
clalist Society in Paris, would be going
too far.
! Since there are so many copying
processes being invented these days,
and as there seems to be a mania for
duplicating and multiplying letters, cir
culars, etc., we feel like giving our
readers the benefit of all we can learn
on the subject. Hence we give here
with the art of Typography, simple
and easy mode of printing, by which
mode any number of copies of letter,
drawing or circular may be produced.
Our authority is Prof. Thomas Bolas,
+. c. S., who recently read a paper be-
fore the London Society of Arts, de-
scrlDlng this process in the following
manner: Typography, he said, Is sim
liar to TYPOGRAPHY, except that zinc
plate is employed in the place Of the
photographic stone. The so-called
transfer paper is merely a moderately
| fine paper which has been brushed over
on one side with a mucilaginous mix
tuge prepared by boiling together 1000
parts OF water. 100 Of starch, of gam
bOge. and / Of glue. This paper is
written upon with the ordinary COM
morcial photographic writing ink, which
has been rubbed up with water like an
ar lists water-color. The writing be-
ing dry, it is necessary to moisten the
back of the transfer by means of damp
sponge. after which it is laid face down
ward on q sheet of ordinary roofing
ziEc, which has been previously clean
ed by means OF emery cloth. Both be-
inE now passed together under theroll-
lta%ofa small press, the transfer adj
heres to the metal plate; but on damp
ening the back of the paper it becomes
easily removable, leaving the writing
on the zine. The face of the zinc plate
is now gently rubbed over with mucil-
age of gum arabic, which is all the bet
ter for being sour, and the excess of
gum having been sponged off, an India
rubber mixing roller, charged with or
binary printers ink, is passed over the
| still damp zinc plate few times. The
ink takes only on the lines of the
transferred writing, and it is now
merely necessary to lay sheet of white
paper on the plate and to pass both
through the press to obtain an impress
sion-an exact reproduction of the
original writing. Any number of cop
les can be printed by repeating the OPP
erations of dampening and linking.
Typography, thus simplifed, is rapid,
economical, and within the reach of ev-
cry one.
