FIG. 1758. 



APPARATUS FOR EXHIBITING THE DISSOLVING YIEWS, WITH 

 IMPROVED FOUNTAIN ARGAND OIL LAMPS. 



The enchanting optical effect termed Dissolving Views is produced by means 

 of two Phantasmagoria Lanterns, so arranged on a stand that the centre of the discs 

 or pictures projected by each are coincident, and the dissolving or blending of the 

 pictures is effected by a contrivance in front of the two Lanterns, which gradually 

 shuts off the image thrown from one Lantern, whilst the other becomse gradually 

 clearer, until a perfect picture is seen on the disc ; a fresh picture being put into 

 the darkened lantern, the action is reversed.

consisting of two of Negretti and Zambra's Superior 



Lanterns of Japanned Metal with Rackwork adjust- 

 ment to the front Lenses, mounted, with Dissolving 



Apparatus. Fig. 1758, or mounted as fig. 1765, page

Argand Oil lamps and Reflectors. It is simple in

Messrs. Negretti and Zambra can confidently recommend the Apparatus at 10 10s. as being of the most 

 improved construction, and particularly adapted for the purpose of instruction or amusement, where the 

 expense or trouble of the Oxy-Calcium or Oxy-Hydrogen Light cannot be undertaken. If desired, Paraffin 

 lamps can be supplied to these Lanterns, as mentioned on the previous page, in place of Oil Lamps.
