XYLO-IODIDE OF SILVER, exclusively used at all the Pho- 

 tosrraphic Establishments. — The superiority of this preparation is now universally ac- 

 knowledged. Testimonials from the best Photographers and principal scientific men of the day, 

 warrant the assertion, that hitherto no preparation has been discovered which produces 

 uniformly such perfect pictures, combined with the greatest rapidity of action. In all cases 

 where a quantity is required, the two solutions may be had at Wholesale price in separate 

 Bottles, in which state it may be kept for years, and Exported to any Climate. Full instructions 

 for use.

MR. T. E. MERRITT'S IM- 

 PROVED PATENT CAMERA. 



This has, by several eminent Photographers, 

 been pronounced to be the best yet offered to 

 the public. For all the Paper, Albumenized, 

 and Moist Collodion Processes, it is at once 

 facile, perfect, and portable ; and as many 

 pictures as may be desired may be taken in 

 succession , and dropped into a receptacle pro- 

 Tided, without the possibility of injury from 

 light. And, if requisite, those in Collodion 

 maybe developed, so that the quality of the 

 light may be ascertained.

THE CALOTYPE PROCESS.— 

 A HANDBOOK to PHOTOGRAPHY 

 on PAPER. By THOMAS SUTTON, B.A., 

 of Caius College, Cambridge. 



**» The Process described in this treatise is 

 so certain that it may fairly be called Infal- 

 lible. It gives the utmost clearness and sharp- 

 ness of definition, and renders admirably the 

 atmospheric effects of landscape. The cer- 

 tainty of this Process consists in the fact, that 

 the mode of development is adapted to the 

 exposure that may have been given to the 

 picture, so that over-exposure is scarcely pos- 

 sible, and the details of tiic deepest shaefows 

 may in this way be fully brought out without 

 injury to the lights ; and intense blacks may 

 always be obtained. It is peculiarly the Pro- 

 cess for the tourist, and pictures of immense 

 size may be taken with great certainty. 



The author will be in attendance at the 



Photographic Institution for a few weeks, for 



the purpose of demonstrating the Process to 



Pupils, at a charge of Three Guineas each.
