228 NEGEETTI AND ZAMBRA, HOLBORX VIADUCT, E.G., 



FIG. 762. 



NEGRETTi AND ZAMBRA'S GRAPHOSCOPE, 



FOR VIEWING PHOTOGRAPHS, DRAWINGS, AND PICTURES OF EVERY KIND, 



As constructed and Patented by its Inventor, Mr. C. J. ROWSELL, and shown in the 

 class " Scientific Inventions," at the International Exhibition (1871). 



So simple is this instrument, that little need be said as to the mode of using. 

 It can be focussed to suit any sight the oldest or youngest, the longest or 

 shortest. Plain or Coloured Photographs, when viewed through the Large Lens, 

 will be found to stand out with the roundness and reality of natural objects. It 

 occupies little space, cannot get out of order, and is an ornament to any 

 drawing-room. The G-raphoscope may be used either by day or night. 



In the beautiful Photographic "Nature Printing," there is much that the 

 unassisted eye cannot perceive, but which appears among the distincter portions 

 portrayed, as a dark or light mass only. The Graphoscope, by a simple but 

 effective arrangement, and a powerful Lens easily adapted to any focus, " brings 

 out " and gives a Stereoscopic life-like effect to this, and to the whole subject in 

 a very pleasing and beautiful manner ; also, by a simple combination, it forms a 

 perfect Stereoscope for both Opaque and Transparent views. The Graphoscope, 

 with an appropriate selection of Coloured or Plain Photographs, forms a most 

 elegant Wedding or other Present.

 Negretti and Zambra have always in Stock a collection of Photographic Yiews 



of London and various parts of the World Photographic Flowers and views of 

 the Crystal Palace, Sydenham both coloured and plain, Statuary, &c., &c. 



766 Plain Photographic Yiews, 2s. 6d., 4s. 6d. ; Coloured Flowers and Yiews, 

 4s. and 5s. 



A vase containing a bouquet of Natural Flowers placed in the field of the large 

 lens forms an exceedingly interesting object. When the Graphoscope is used for 

 this purpose it should have the easel turned down flat upon the base. 



Cartes de Visite, Portraits, &c., are very effective under the Instrument.
