NOTES AND QUERIES. 



[No. 175. 



PHOTOGRAPHY— XYLO- 

 lODIDE OF SILVER, prepared salely 

 by B. W. THOMAS, has now obtained an 

 European fame ; it supersedes the use of all 

 other preparations of Collodion. Witness the 

 subjoined Testimoiilal. 



"122. Regent Street. 

 "DearSir, — In answer to your inquiry of 

 this morning. I have no hesitation in saj-ing 

 that your preparation of Collodion is incom- 

 parably better and more sensitive than all the 

 advertised CoUodio-Iodides, which, for my 

 professional purposes, arc quite useless when 

 compared to yours. 



" I remain, dear Sir, 



" Yours faitlifully, 



" N. Henneman. 

 Aug. 30, 1852. 

 Tb Mr. R. "W.Thomas." 



MR. R. W. THOMAS begs most earnestly to 

 ■caution photographers against purchasing im- 

 pure chemicals, wliich 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- 

 principled persons. To prevent imposition each 

 fcottle is stamped with a red label bearing the 

 maker's signature.

 at the centre and margin of the picture, and 

 have their visual and chemical acting foci 

 •coincident. 



Great Exhibition Jtirors' 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 furnished with a double 

 achromatic object-lens, about three inches 

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

 the image very perfect up to the edge."
