 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 general^ supposed to be of 

 modern invention. 



The stand of the microscope is of ebon}'-, and is a fine 

 specimen of geometrical turning. The optical part is of 

 course very poor, and inferior to the very chepvpest achro- 

 matic instrument of the present day.
