Card—The subscriber having purchased one-half of the proprietor’s entire Right for Cutting’s Patent Ambrotypes in the city of Boston, has associated himself with Mr. A. H. Knapp, a successful Artist, for the purpose of taking these beautiful and endearing pictures, In Glass.

The Ambrotype, being hermetically sealed between two plates of fine polished glass, (by a cement which not only secures, but gilds and beautifies the impression,) is proof against the action of water or acids, or the variations of climate in long sea voyages.  Hence they are named “Ambrotypes,” “immortal, imperishable.”  They can be taken from the size of full life to the smallest miniature, and in one-quarter of the time of the Daguerreotype.  They are not reversed, and can be seen in any light as plainly as an engraving; hence are very suitable for pins, Lockets, and large Frames, as well as Cases.

The extreme popularity of the Ambrotype has given rise to much imposition.  Counterfeits upon single glass, covered with black varnish, are often sold for Ambrotypes.  None are genuine without the patent stamp.  The public are invited to call and examine specimens.  J. Briggs.

For Sale, The Patent Rights For an Entirely New Light, which has the following characteristics:—

1st.  It cost less than one-fifth of any other practical artificial light.

2d.  It is a perfectly steady light, so that persons with dim or weak eyes can use it without unpleasant results.

3d.  It is capable of being adjusted to the nice lamps now in use.

4th.  It is never out of order.

5th.  There is nothing unpleasant about it.

6th.  It is perfectly safe.

All this is clear, palpable reality to the beholder; and believing that it must at once come into general use, and wishing to send it broadcast, we have adopted a simple plan and scale of disposing of the rights to the same by counties or States, in such a way that without risk all persons of fair capacity and industrious habits can be sure of replenishing their pockets, or of adding largely to an already ample treasury. 

The light may be seen in all its detail, at No. 1 Basement of Old State House.  A. H. Knapp & Co..
