If any object through which the light passes unequally in its various parts be brought close against a sensitized paper used by photographers in printing pictures from their negatives, it is evident that an impression will be produced. This print will be a negative, or, in other words, the dark parts in the subject will be light and the light parts dark. For example, the section of papaw wood shown in Fig. 1 is a negative, while in Fig. 3 is the
