This is the 8th edition of the famous book Désiré Van Monckhoven published about photography. This is one of the few copies where the edition number isn't changed in "Huitième edition" during the reprint of the 7th edition! (See entry nr. 616 on page 291 in "Belgian Photographic Literature of the 19th Century" by Steven F. Joseph for more information)
With 183 wood engravings in the text, 431 pages. No photographic prints, only the posthumous editions of this work had them.
Printed by Annoot-Braeckman, Ghent in a print-run of 3300 copies.

The 7th edition was printed in 1880, the 8th in 1884. This is one of 1884 with the wrong edition number.
