We place inside of the camera, and about one-tenth of the focal distance of the lens from the glass, a board having an aperture of any desired pattern that we wish the edges to have. This board shades the edges of the glass, thereby leaving them transparent in the picture. Then the picture, being taken in the usual manner, is finished by varnishing with transparent white varnish, and then backed with japan varnish, care being taken to have the japan on the back extend only to meet the inside edges of the mat. Then we place the mat back of the picture and secure it in its place with the preserver. If applied to the process, as patented by J. A. Cutting, with two glasses, the picture is made as above described, and then the second glass is applied, and finished as before by backing with japan. The advantage of our improvement, is in having the mat protected from being soiled, and making the picture appear more round, causing an illusion as though the picture or image was suspended in the atmosphere, clear from the background. Having thus fully described the nature of our invention, what we claim therein as new, and desire to secure by Letters Patent, is, making the border of the picture transparent and placing the mat back of the picture, as described in the above specification, and for the purpose set forth. _Witnesses to the signature of A.

Day. _Dated May 27th, 1856._ * * * * * PATENT FOR THE APPLICATION OF COLORING SUBSTANCES, OR MATTER, TO PHOTOGRAPHIC IMPRESSIONS. Be it known that I, Giles Langdell, and Marcus A. Root, of Philadelphia, in the State of Pennsylvania, have invented a new and improved mode of coloring daguerreotype and other photographic portraits or pictures made on glass, metal or other material; and we do hereby declare that the following is a full and exact description:-- The nature of our invention or discovery consists in providing and applying both mineral and vegetable coloring matters in solution to the daguerreotype or any other photographic impression, introducing the said coloring matter either into the collodion or the developer, or by pouring upon the plate after the impression is fixed by hyposulphite of soda, or the cyanide of potassium, or by any other means. The several coloring substances, E. G. red saunders, alkanet, dragons' blood, &c., &c., can be used separately or in conjunction or compounded with various mineral substances, or with any coloring matters obtained from other roots, woods, gums or other vegetable matter, the proportions or quantity employed being varied or regulated by the lightness or depth and strength of tone which may, from time to time, be required.
