THE MICROSCOPE 17 



The Medium-sized Stand, H. III. (by C. Eeichert, Vienna ; 

 agents, H. F. Angus & Co., London), is an efficient type of 

 instrument of low price which can be supplied with all neces- 

 sary movements both above and below the stage. It can 

 also be obtained with the English type of foot, thus ensuring 

 greater stability. The handle attachment is convenient when 

 moving the instrument after adjustments have been made, 

 and when replacing it in position on the camera base.
