This should be done by applying a little heat, and gilding very slowly, giving a coating of gold with the greatest possible uniformity.

By this method, I have been enabled to produce any number of proofs.

I have produced a dozen from one impression, and it remains as perfect as when first taken.
"By a little judgment and care the operator will be enabled to produce the electrotype copy of the Daguerreotype plate without any difficulty.
The electrotype copy should be immediately put under a glass and sealed in the same manner as the ordinary Daguerreotype." CRAYON DAGUERREOTYPES.
This process is patented in the United States, by J.A.Whipple, of Boston, and of course no honorable person will use it for his own benefit without purchasing a right.
A white back-ground is generally employed, the object being to blur the lower portion of the plate, leaving the head of the subject in relief.
Every Daguerreotypist is familiar with the fact that a motion of any body between the camera and the sitter will cause a "blur." Cut a piece of thin paper and scallop it, making a semicircle.

This is kept straight by means of a wire frame, and it is to be moved in front of the lower part of the body of the sitter during the time of exposure of the plate in the camera.

Develop over mercury as usual, and the result will be a crayon Daguerreotype.
Another method is to have a wheel with a hole cut through it of a diameter of about 12 inches.
