in the hands of the photographer.

IMPROVEMENT IN COLLODION.--J. B. HOCKIN & CO., Chemists, 289. Strand, have,

by an improved mode of Iodizing, succeeded in producing a Collodion equal,

they may say superior, in sensitiveness and density of Negative, to any

other hitherto published; without diminishing the keeping properties and

appreciation of half-tint for which their manufacture has been esteemed.

Apparatus, pure Chemicals, and all the requirements for the practice of

Photography. Instruction in the Art.
