No. to London Mictoscope. 
The No. 10 microscope is a simple instrument suitable for general purposes and especially 
for school work where the highest powers are not employed. The adjustments are simple to use 
and the construction is very robust. 
The microscope is of the vertical type, without joint for inclination and with one focussing 
adjustment by means of a specially cut rack and pinion giving very smooth motion, free 
[from backlash, capable of focussing object glasses up to 4 in. The base with the handle 
shaped limb is made in a solid casting, giving great rigidity. The stage is square, and is 
provided with stage clips for holding specimens. The body tube has an adjustable drawtube. The 
mirror is plane on one side and concave on the other, and is held in gimbals. The instrument 
is finished in acid resisting stoved black enamel. 
The eyepieces and object glasses are of our standard series.
