 lODIDE OF SILVER, prepared solely 

 by R. W. THOMAS, has lujw ubtuiued an 

 European fame ; it superse<les the use of all 

 otiier 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 saying 

 thac your preparation (if Collodion is incom- 

 parably better and more sensitive than all the 

 advertised CoUudio-Iodides, which, for my 

 professional purposes, are quite useless wheu 

 compared to yours. 



'■ I remain, dear Sir, 



" Yours faithfully, 



"N.Hknjjeman.

 To Mr. R. W. Thomas." 



MR. R, W. THOMAS begs most earneitly to 

 caution photograjjliers against purchasing im- 

 pure chemicals, which are n(»w t(x> frequently 

 sold at very low prices. It is to thiscauae uearly 

 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, Cliemist aud 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 mi- 

 mincii>le(l persons. To prevent imposition each 

 bottle is stamped with a red label bearing the 

 maker's signature.
