ehromos are spoken offs the

When a chrome is made by a
competeht'Rand, it presents an
exact counterpart of the origi,
nal painting, with the delicate
graduations of tlnts and shades,
and with much of the spirit
and tone of a'production a Of
the brush and pallet.
To understand how chromos
are made, the art of litho-
graphy must first be briefly ex'
/ plained. The stone used in
lithographiug is a species OF
limestone found in Bavaria, and
lis wrought into thick slabs
with finely polished surface.
The drawing is made upon the
slab Witha sort Of coloredsoap,
which adheres to the stone,
| and enters into q chemical com.
tinution @ithit after the ap
plication Of certain acids and
gums. When the drawing is
complete, the slab is put on
the press, and carefully damp
ened with 2 sponge, The oil
color'(or ink is then applied
with common printers roller.
OF course, the parts Of the
+ slab which contain no drawing,
being wet, resist ink; while
the drawing itself, being oily
repels the water, but retains
the color applied, 1t is thus
that without a raised surface
. or incision-as in common
