ssss1 represents a small "Jenny Lind Stand," and is a very convenient article for the sitter to lean a hand or arm upon while sitting for a portrait; It is fixed with a rod for raising or lowering the top, and can be adjusted to any required height.
Head Rests.
HEAD RESTS.
There are several patterns of head supports, or, as they are commonly called, head rests, in use by the profession. I give two illustrations (Figs. ssss1 and ssss1). The first is an independent iron rest, known as the "Jenny Lind Rest;" and the other is for fastening to the back of a chair, as seen in the cut. For general use, I would recommend the iron independent rest as far more advisable than any other.
Vices for Holding Glass.
PLATE-HOLDERS, BATH, DIPPING RODS.
The article used for holding the glass, during the process of cleaning, is called a vice; and, of the numerous styles recently introduced, I find none that I would prefer to the old one known in market as "Peck's Vice;" it is simple and easy in operation, and at the same time is effectual. ssss1 represents this vice, which is to be firmly secured to a bench; the small piece of wood attached to the bottom is of no use. A A are the grooved for receiving the daguerreotype plate-block; but as they are too deep for the glass, I pin on a small strip of wood, so that the upper edge of the glass will be a little above the projection of the vice.
