C. E. F. and T. D. (Leeds). Your inquiry as to the best mode of constructing a glass chamber for photographic purposes will be answered in our next.
Mr. John Cook has sent us a plan for taking cheaper pictures for stereoscopic purposes by means of a common camera, and the substitution for the ordinary ground glass of a piece of plate glass and a piece of paper, on which the outline of the figure is to be traced. When one sketch is thus made, the camera is to be moved fifteen or sixteen inches to the right or left, and a second drawing made in the same way. The plan is a very obvious one; and though adapted for those who can draw and have an ordinary camera, it presents few advantages to photographers.
