This process is also patented, and the remarks on the preceding subject
will apply in this case. The plate is prepared and exposed as in the

exposing it to the vapors of mercury, put a small mat or diaphragm,
having a small hole through it, over or directly on the surface of the plate.
This diaphragm should be bevelled, and the bevel should be towards the surface
of the plate; this, in order to prevent too sharp a line on the impression.

over the mercury, it will be developed on such portions only as are exposed.
The principle is so familiar that further explanations are unnecessary.
