This case-mounted microscope, when assembled with the compound tube, 
is 11½-inches in height measuring from the table top. The case 
dimensions are 6 x 5¼ x 1½-inches. It is unsigned by the maker 
and is likely English dating from the mid-19th century. 
The main focusing adjustment is accomplished by sliding the 
stage up and down along the cylindrical pillar, while the knob 
on top of the pillar functions as a fine focus adjustment  
by slowly moving the inner tube with the attached limb and optics. 
The microscope comes supplied with a Huygenian eyepiece 
and four separate objectives of different magnifications that are 
used singly. In addition, it is supplied with a 
brass trough with glass bottom for wet work, a glass stage 
insert, and stage clips. The microscope can be use with or 
without the compound tube.
