PHANTASMAGORIA LANTERNS, 



These celebrated phantasmagoria lanterns are manufactured by L. CASELLA, with 

 every improvement in the lamps and lenses, as well as in mechanical arrangements, by 

 which the exhibitor obtains a much larger and brighter picture than can be had with 

 lanterns of the old construction. 



To schools, mechanics' institutions, etc., they offer peculiar advantages, and are 

 extensively used by the managers of such institutions in aiding the .progress of science 

 and education.

DISSOLVING VIEW APPARATUS, 



The beautiful optical effect termed dissolving views, is produced by means of two 

 phantasmagoria lanterns, arranged as No. 1812, standing so that the projected 

 centres of the discs or pictures are coincident, and the dissolving or blending of the 

 pictures affected by the rackwork contrivance in front, which gradually shuts off the 

 image of one lantern, whilst the other becomes clearer and more developed, a fresh 

 picture being in the meantime put into the darkened lantern, and is reproduced or 

 dissolved by reversing the action.
