W. WATSON & SONS’ “ROYAL” 
MICROSCOPE 
Particulars of the 
above, and of all of 
Watson’s 
Microscopes, are 
contained in their 
Catalogue, 
post free on request. 
This instrument is of medium 
size, but designed and built 
to give maximum rigidity and 
perfect working with highest 
powers. 
The Stage is built with a con- 
tinuous casting to enfold the 
Limb, and is not merely screwed 
to it. 
The Body has two Draw Tubes, 
one extended by rackwork and 
the other sliding. The Stage has 
a long motion horizontally, and 
is fitted with a sliding bar. The 
Sub-stage can be supplied with 
a Fine Adjustment, if desired. 
This is one of the best Micro- 
scopes that is made for the 
photo-micrographer and those 
who appreciate fine mechanical 
design and craftsmanship.
