thought that the microscope was not more than 120 years 
old, and was made by the elder Adams. He said that many 
of these old microscopes in finish of brass-work, good fitting 
and screws would compare very favourably with instru- 
ments of recent construction, and that the appliances and 
apparatus of one of the complete microscopes would surprise 
a microscopist of the present day; he would find many parts 
and adaptations which are generally supposed to be of 
modern invention. 
The stand of the microscope is of ebony, and is a fine 
specimen of geometrical turning. The optical part is of 
course very poor, and inferior to the very cheapest achro- 
matic instrument of the present day.
