ORTHO-PROCESS PLATE.

This plate is specially made for process workers, and will
be found excellent both for line and half-tone work. Its
orthochromatic properties and extremely fine grain, combined
with its density-giving power, make it also of great value to
the commercial photographer. For copying documents, blue
prints, coloured diagrams, etc., it is, we believe, unequalled.
The speed is 100 H. & D., 80 Watkins, or F/56 Wynne.

9. WELLINGTON X-RAY PLATE.

Intended exclusively—as its name implies—for X-ray
work, this plate has achieved great success during the war.
Its exceptionally high speed, and the beautiful quality of the
radiographs which can be obtained by its use, have gained for
it a high place in the appreciation of the medical profession
and of radiographers all over the world.
A booklet dealing exclusively with the WELLINGTON
X-RAY PLATE will be sent on request.

10.—WELLINGTON LANTERN PLATE.

This plate is recommended to those who require a lantern
plate of medium speed. It is especially suited to the making
of lantern slides by reduction, and may also be used for making
enlarged transparencies for window decoration and similar
purposes.
Cold black, warm black, brown and sepia tones may be
obtained in development, and almost any colour by after
toning.
The H. & D. speed is 6.
