School Projection Apparatus 



Lantern Arranged for Microscope Projection. 



A New High Grade Projection Lantern at a Low Price 



This new model is simplified to the greatest degree consistent with 

 practical utility, making it particularly easy to operate, and yet, com- 

 bining all the useful attachments of the high priced lantern. The 

 workmanship is excellent throughout and the design gives rigidity, 

 optical accuracy and convenience found in no other low priced lantern. 

 The lathe bed construction as in our high priced lantern is followed. 



CONVERTIBILITY. This lantern can be used either single or 

 double for projection of lantern slides, microscopic objects or opaque 

 objects. No other low priced lantern has such a range of application. 



NEW ELECTRIC LAMPS. The light is a matter of importance 

 in a lantern. Our two new hand feed lamps provide for any voltage 

 or amperage and any form of current. The triple condenser sj-stem, 

 cooling cell, detachable bellows, new lamp box of corrugated metal, 

 etc., are all features of value.
