We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

Larger cameras are manufactured, so that negatives of any size may be reduced to the proper lantern-slide size. When a slide is to be made in this camera, the lens is first screwed into its front board and put in place; the negative is placed in the frame at the end of the camera farthest from the ground-glass, in such a way that the gelatine side is toward the lens and the image is upside down. Then place the camera against a window at such an angle that it points directly toward the sky (not the sun), resting the lower end upon a table, or it may be directed toward a large piece of white cardboard brilliantly illuminated by daylight. The lens frame is then pulled back from the negative the distance which the lens requires to form the image of the desired size. This dis- tance depends upon the focus of the lens, and must be ascertained by experiment. Suppose it to be 14 inches. Then move the ground-glass carriage back and forth until the image upon the ground-glass is very sharp. This image will be right side up, but right for left as one sees himself in a mirror.
