Harrington, Sarah.—“A new and curious method of taking and reducing shadows, with appendages and apparatus never before known or used in the above art, for the purpose of taking likenesses, furniture, and decorations, either the internal or external part of rooms, buildings, &c., in miniature.” The person whose likeness is to be taken is placed so “as to procure his or her shadow to the best advantage, either by the rays of the sun received through an aperture into a darkened room, or by illuminating the room.” The face is then brought “directly opposite the light, so that the shadow may be reflected through a glass (or transparent paper);” the glass is movable in a frame “so as to fix it on a level direction with the head of the person.” The outline of the shadow is then traced with a pencil, &c., after which it is “reduced to a miniature size by an instrument called a pentagrapher.” Respecting furniture, &c., “the articles required to be taken are to be placed in such a direction that their shadows may be reflected as above described, traced out in the same manner and reduced.” The shadows (as also the likenesses) are cut out “and placed upon black or other coloured paper or any dark body” and the external parts are, if required, decorated with cut paper, &c. When a likeness is to be taken, accompanied with the external “part of a room or buildings,” a camera obscura is used; the reflected shadows are received on paper, the outlines are carefully marked, and then “either fill’d up with Indian ink or coloured, or cut out as above directed.” [Printed, 4d. No Drawings.] On December 22nd, 1806, Charles Schmalcalder applied for a patent for a machine of the same type, but of more complicated construction. We give the abridged specification, for it forms a humble though important link in silhouette history, having been much used by itinerant silhouettists at the beginning of the nineteenth century. _A.D. 1806, December 22.—No. 3000._
