GRAMERCY-PRECISION BALANCES 



Made Entire of Magnalium For Students' Use and Technical Purposes 



The 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.
