This Plate is intended to show another important application of the
photographic art. Fac-similes can be made from original sketches of the
old masters, and thus they may be preserved from loss, and multiplied to
any extent.
This sketch of Hagar, by Francesco Mola, has been selected as a specimen.
It is taken from a fac-simile executed at Munich.
The photographic copying process here offers no difficulty, being done of
the natural size, by the method of superposition.
