SOCIETY OF ARTS' PRIZE 

 MICROSCOPES. 



CAUTION TO THE PUBLIC. 



THBSociety of Arts awarded the Prize Medals for both the Stu- 

 dents' and School Microscopes to Messrs. B. Fik.ld & So»r, Bir- 

 minsham. The Microscopes now made are much superior to the 

 original, though the jirice is unaltered. The character they have 

 gained has induced other makers unwarrantably to apply the name 

 to instruments which, resembling them generally in form and in 

 price, are inferior in magnifying power, in number of lenses, and in 

 many other respects. 



The Society of Arts' Prize Microscopes bear the name of 



FIELD & SON, BIRMINGHAM, 



of whom, or their Agents, lUustratiye Catalogues may be obtained, 

 post feee, for Two Penny Stamps.
