Experience has d»monstrated their superiority in optical efficiency, dura- 

 bility, and ease of manipulation. 



Our Model F embodies many practical and valuable improvements. Its 

 long curved handle arm with a large stage provides unusual space for ob- 

 ject manipulation. Stage is completely rubber covered— top, edges and 

 bottom. Ample room is provided between the edge of fine adjustment 

 head and the arm for free play of fingers.
