MISCELLANY.

The public lose much by counterfeit notes and there is no way of securing them against such loss as long as copper plate prints are used. What one artist has done another of equal skill may imitate, or the original artist may—for fraudulent purposes copy. I offer them a method that I have invented, by which plates can be produced that can neither be imitated by the artist who produced them, nor by any other. This method is by using glass plate.

In common notes there is, besides the words and characters that go to compose the note, some emblematical representations, such as a coat of arms, a building, a landscape, &c. all evidently wrought by hand. Now in the glass plate notes, let there be the usual words &c. but instead of the emblematical parts let there be a variegated representation which shall be the work of chance. Let the etching be performed by the chemical action of a mordant. The engraver then by which imitations can be so dexterously executed will be rendered in this case quite useless.

A glass plate will give fifteen or twenty thousand impressions, good proof, while the copper plate will be worn out with four thousand. Copper can be engraved in a hundred different ways, while glass can only be engraved in two ways—with fluorick acid and with a wheel.

The variegated marbling produced on glass by a chemical agent can never be imitated by any thing else even the same person cannot produce two similar plates.

Can the imitator, baffled on glass, resort to copper and apply the engraver? Can he suppose him to imitate their first er—(make scans corner section? No—The glass differing in its nature from the copper, and the manner of operating upon them being different, those differences must produce very different effects—but still, could they be the same, the impressions would have a different close and an appearance every way different, which gives the great desideratum—a method of preserving prints that cannot be imitated.

I therefore declare to all the banking companies in the United States, that if they will adopt my method, the public will be no more defrauded with counterfeit notes, and their notes shall on account of that security obtain a currency and a credit which they cannot otherwise acquire.
