Microscopes 



When youbuy a Bausch & Lomb Micro- 

 scope, you buy the cumulative results of 

 66 years of optical endeavor and manu- 

 facturing experience. 



During that period we have developed 

 every optical refinement and mechanical 

 improvement demanded by the practices 

 of modern microscopy. 



Our optics — designed, tested and con- 

 trolled in manufacture by our own Scien- 

 tific Bureau — have withstood the most 

 exacting, long-time tests of research labo- 

 ratories. 



Our side fine adjustment is of the most 

 approved lever type — highly sensitive and 

 durable. 



There is a Bausch & Lomb model for every microscopical require- 

 ment. Write for our new complete catalog.
