168 THE FERROTYPE, length of time required for exposure. I began to cast about for means to shorten the time of exposure. Having already the quickest working Collo- dion, etc., that I supposed it possible to produce, I arrived at the conclusion that I 'could do nothing in that direction, but must direct my efforts to make the prism more effective as a reflector. I had, I supposed, been using only its refractive power as yet. One day, as an experiment, I removed the prism from the case, and, taking out the velvet, I inserted in its place a piece of white card- board, and, to my surprise, on again trying the exposure, I found that by this simple means I was enabled to reduce the time of exposure about one-half, and got quite as perfect an image. This surprised me, as I knew that the surface of the card-board possessed a very low reflecting power, and also that its surface must be very un- equal, but it seemed that the prism corrected any defect arising from such inequalities of surface. In this way I was at once put on the right track to the long-desired object. Taking my prism to the silver plater, I had a coating of metallic silver deposited upon its largest surface, which I caused to be covered with a strong varnish to protect it from friction, etc. I again placed it in its case, and, as may be imagined, with trembling anxiety prepared to try again its reflecting powers. Upon coating a plate and subjecting it to an
KON-KEVEESED FERROTYPES. 159 exposure of ordinary duration, I was overjoyed to find my highest hopes realized—I had secured a perfect reflector by which to produce Non-reversed positive pictures by the Collodion process. The two cuts herewith given will convey a perfect idea of one ofmy methods of mounting the prism for work. Fig. 1. Fig. 2. Figure 1 shows the prism in its brass case as it rests upon the camera box. This particular reflector is of 4 inches diameter on the two faces of its right angle ; the reflecting surface or back is 4x5^. It is mounted in a brass case made to sci-ew on the front of a |^-tube, the open- ings being made large enough to receive and transmit all the light the 4 inch front will admit.
