Heal Attachment. 



In order to use larger condensers, as well as the most 

 approved form of the vertical attachment, the brass cells 

 for the two elements of the larger condenser are hinged 

 together and held in place by a pin. The back cell is held 

 to the shortened Sciopticon body by a bayonet joint. 



For the vertical attachment the front element of the 

 condenser, mounted as above, opens to a horizontal posi- 

 tion, and is held in place to a tall draw-front, which holds 

 the, objective and mirrors, in the usual form. 



The price of the Gas Seiopticon, with the 5-inch con- 

 denser, mounted as above described, is $65.00. 



The price, with the 4Hnch condenser, etc., thus mounted, 

 is $60.00. 



The same, with the vertical attachment added, is $70.00. 



These condensers, the vertical attachment, and the achro- 

 matic microscopic attachment are only used with the lime 

 light. 



Dissolving Apparatus. 



The Crescent-shaped Dissolver (see Manual, p. 40, Fig. 

 16 j now extends five narrow fingers each way, in order to 

 more thoroughly blend the pictures over the whole disk, 

 during its passage from side to side. 



The rod b (Fig. 17), instead of being held by springs out- 

 side, between the lanterns R. L. (Fig. 16), now passes just 

 under this surface, through holes in the ends of the case. 



Instead of the arms c (Fig. 17), the end is now bent into 

 a crank, which is limited in passing from side to side by 

 stops in the case, so as just to allow the dissolver to cover 

 the objectives alternately. When pictures from both Sciop-/ 

 ticons are shown upon the screen at the same time, as in 

 the Soldier's Dream, etc., the crank is sprung over the stop, 

 so as to point upward, while the dissolver hangs downward.
