ROSS'S PHOTOGRAPHIC 

 PORTRAIT AND LANDSCAPE 



LENSES.— These lenses give correct definition 

 at the centre and margin of tlie picture, and 

 have their visual and chemical acting foci 

 coincident. 



Ch-eat Exhibition Jurors' Reports, p. 274. 



" Mr. Ross prepares lenses for Portraiture 

 having the greatest intensity yet produced, by 

 procuring the coincidence of the chemical ac- 

 tinic and visual rays. The spherical aberra- 

 tion is also very carefully corrected, both in the 

 central and oblique pencils." 



" Mr. Ross has exhibited the best Camera in 

 the Exhibition. It is ftirnished with a double 

 achromatic object-lens, about three inches 

 aperture. There is no stop, the field is flat, and 

 the image very perfect up to the edge."

PHOTOGRAPHY.— XYLQ. 

 IODIDE OF SILVER, prepared solely 

 by R. W. THOMAS, has now obtained an 

 European fame ; it supersedes the use of all 

 other preparations of Collodion. Witness the 

 subjoined Testimonial. 



" 122. Regent Street. 

 "Dear Sir, — In answer to your inquiry of 

 this morning, I have no hesitation in sajang 

 that your preparation of Collodion is incom- 

 parably better and more sensitive than all the 

 advertised Collodio-Iodides, which, for my 

 professional purposes, are quite useless when 

 compared to yours. 



" I remain, dear Sir, 



" Yours faithfully, 



** N*. Hennbman. 

 Aug. 30, 1852. 

 To Mr. R. W. Thomas." 



MR. R. W. THOMAS begs most earnestly to 

 caution photographers against purchasing im- 

 pure chemicals, which are now too frequently 

 sold at very low prices. It is to this cause nearly 

 always that their labours are unattended with 

 success. 



Chemicals of absolute purity, especially pre- 

 pared for this art, may be obtained from R. W. 

 THOMAS, Chemist and Professor of Photo- 

 graphy, 10. Pall Mall. 



N.B —The name of Mr. T.'s preparation, 

 Xylo- Iodide of Silver, is made use of by un- 

 Dnncipled persons. To prevent imposition each 

 bottle is stamped with a red label bearing the 

 maker's signatiure. 



TO PHOTOGRAPHERS. — 

 Pure Chemicals, with every requisite for 

 the practice of Photography, according to the 

 instructions of Hunt. Le Gray, Br(?bisson, &c.

 phic and other purposes.

 for 1000?., the annual payment for which is 

 HI. Is. 8rf. ; in 1847 he had paid in premiums 

 168/. Us. 8(i. ; but the profits being 2J per cent, 

 per annum on the sum insured (which is
