=NATURE PHOTOGRAPHY.=

All Naturalists who wish to take up this fascinating and valuable art

are invited to communicate with =Messrs. J. H. DALLMEYER, Limited=,

who have supplied complete outfits or Lenses to nearly all the leading

experts in this branch, and are therefore peculiarly qualified to give

advice, and to make or select apparatus according to the requirements

of each individual case. In no branch of photography is the choice of

apparatus more difficult to the uninitiated, as it is quite possible to

acquire the most perfect and costly outfit, and to find it of little

practical application for the special work for which it was procured.
