Microscopes 



The Accepted Standard 



Models for every purpose, in laboratory, 

 classroom or for special research work — 

 backed by 65 years of optical experience. 

 Combine every approved feature of me- 

 chanical design with the highest grade, 

 precision optics. 



Because of the demands made upon our 

 resources for some of the government's 

 most important military needs, we are 

 unable to make microscope deliveries for 

 the present. While proud to be of service 

 in this world crisis, we shall expect to 

 serve our other patrons even more effi- 

 ciently than before, when the world is 

 again at peace.
