Excerpt from A Manual of Photography: Intended as a Text Book for Beginners and a Book of Reference for Advanced Photographers IN preparing a second edition of this manual, rendered necessary by the early exhaustion of the first, the author has endeavored as far as possible to include all the information useful to the working Photographer. A very considerable portion of the matter in the first edition has been cancelled and rewritten, and over a hundred pages have been added, so that fully one-half of the book is new. The number of engravings has been also nearly doubled: all have been engraved expressly for this manual, and, With two or three exceptions only, all have been made, f'ror'njoriginal drawings of the author.
