GRAMERCY-PRECISION BALANCES 



Made Entire of Magnalium For Students' Use and Technical Purposes 



Tlie unsightly appearance of ordinary students' balances, with wooden base and 

 lacquered metal pillar, beam, pans, etc., after they have been in the laboratory for 

 a short time, subjected to acid and other laboratory fumes, has made the Gramercy 

 Precision Balances meet with immediate favor in educational and industrial labora- 

 tories throughout the world. 



The balances are made entirely of magnalium, and lacquered with a durable color- 

 less substance. They are light in weight, most durable, and elegant in appearance. 



The prices are very moderate.
