    This is the same Camera With Lens for Single Views; of the most artistic pro- portion, viz., Length]equal to once and half of Depth. The Dark Slides are Barnett’s Patent (American). As a practical photographer I recommend these to other practical photo- graphers, for they have a decided advantage over English Dark Slides. We must admit that the best English Dark Slides are splendid specimens of cabinet work—(/ do not refer to the “ too cheap ” things sold with 20/- or 40/- Sets)—and, from their style and construction, to be efficient they cannot be too well made; but their “ style and construction,’’which is the same as adopted 25 or 30 years ago, without any improvements, is unnecessarily elaborate for the purpose for which they were intended (entailing the best workmanship, and, therefore, expensive). These Dark Slides are an improve- ment, both in construction and material They are single slides, each containing only one plate, therefore less risk of exposing the wrong plate (as in Double Dark Slides). The Shutter, which is a composition something like vulcanite (but lighter, and not so brittle), is made to draw right out, when exposing the plate. There are no hinges to get out of order and admit light, as in English Dark Slides. The Shutter is easily drawn and replaced, without fear of either sticking at the bottom or scratch- ing the film, as in all Metal Dark Slides and other clumsy contrivances. They are Less than Half the Weight, and not Half the Price (for the same number of Plates) of the best English Dark Slides; they are extremely durable, easy to charge with plates, nice in appearance, besides other advantages. Films may be used in them if desired, and more conveniently than in any other Dark Slides.
