A Dictionary of Photography. Edited by Thomas Sutton, B.A., and

George Dawson, M.A. (Sampson Low.)—The various processes, which are more familiar to us from sundry door-posts in Regent Street than from dark rooms smelling of collodion, are fully described in this useful book. But many other matters of art and science which do not strictly come under the head of photography have also a place, and the handbook is not only complete in its own province, but available for general guidance.
