Bausch |omb BALOPTICON 



Entertains through the sense of sight as the phonograph does through the ear. 

 The Balopticon is not a toy but a very practical instrument, designed to meet 

 every requirement of a projection lantern. Various models for use with lan- 

 tern slides or for the direct projection of opaque objects such as photos, post 

 cards, specimens, etc. Also combination models for both methods, with in- 

 stant interchange. The new gas-filled Mazda lamp gives an illuminating 



equipment superior to the old style arc lamp, but using less 

 current. The entire instrument 13 eimple enough for a child to 

 operate. Prices langa from f.2^.30 up.

Choose Your Children! 



NO ! But you can select your paint. 

 And it pays to be just as particular 

 about it as though you were picking 

 out children. 



Then why not get the guaranteed 

 kind — Statesman Brand — Analyzed 

 and Guaranteed for 5 year- ? It looks 

 well and wears well.
