BALOPTICON 



THE PERFECT STEREOPTICON 



Our recent application of the gas-filled Mazda lamp to projection gives the Balopticon an il- 

 luminator far superior to the old-style arc lamp — and one using less current for equal power. 

 The New Combined Balopticon projects either lantern slides or opaque objects, with instant 

 interchange. It has the new lamp of 1,000 watts, using but 9 amperes of current, instead of 

 35 amperes as used by the arc lamp of equal illumination, and giving much better results on 

 alternating current. Price $120.00. 



Other models for lantern slide or opaque projection from $20.00 up.
