SCIOPTICON MANUAL. 39 DISSOLVING VIEWS. THE STAND. — The peculiar stand represented in Fig. 16, is mostly the one used with Sciopticon dissolving apparatus, and so can better be described with it, but it is not necessarily a part of it. It consists of a well-made walnut box, mounted on two pairs of adjustable legs, attached by fixed thumb- screws and nuts. The back legs are an inch or so shorter than those attached to the front at A, to elevate the range of the lanterns. The back of the stand may be known by the match-lighter G, and by its being nec- essary for the operator from behind to have the open- ing and the box of slides B at his right hand. The slide D stands on end, to separate the used from the unused slides. When the apparatus is taken down, the legs swing together on their hinges, and are tied in a bundle; the open side of the box becomes the top; the instruments occupy the stalls E and F; the djssolver is drawn apart and placed alongside; the caps are removed from the chimney, and placed in the rear; the box of slides occu- pies the space in front; the swing shelf G becomes the lid and is locked down; the strap S and its mate, now hidden under the instruments, meet over the top for one carrier, or serve like the ears of a basket, for two. But as a stand, as seen in the diagram, the front of the box becomes the baseboard, and like any other 13 by 17 inch board, affords suitable standing-room for the apparatus; it is more likely to keep it level than a sep- arate board, as it is dovetailed and firmly fastened in place.
