^ NEW microscope with side 

 fine adjustment of the lever 

 type. The principle is that of our 

 original lever type of fine adjust- 

 ment which has met the test of 

 time and has been very generally 

 adopted. The construction is sim- 

 ple and durable, giving a delicate 

 movement for work with the high- 

 est powers, yet rapid enough for 

 the lower powers. 



The stand is of the same form as 

 our FF and embodies all the good 

 features which have commended 

 that model to so many purchasers.
