THE MICROSCOPE. 



We can reccommend this microscope to pharmacists as an 

 efficient instrument for their requirements; also for general 

 school use, in showing the tissues of plants, circulation of blood 

 and multitudes of other interesting objects. 



Simplicity, strength, and solidity, with low cost of construction 

 are especially claimed for this microscope. The base is a heavy 

 tripod, so proportioned that the microscope is very firm when 

 vertical or inclined. The collar, in which the body tube slides, 

 is firmly dovetailed with and screwed fast to the arm. 



The mirror (concave) is of ample size and swings laterally 

 for oblique light, or over the stage for illumination of opaque 

 objects. A revolving diaphragm to regulate the illumination 

 is attached beneath the stage. 



By means of the draw-tube, the full English tube-length of 

 ten inches may be obtained when desired. 



The plan of constructing the fine adjustment has the follow- 

 ing features especially fitting it for class work in the laboratory
