Stand IV b . 



This stand is of similar construction to Stand IV a , but without the ABBE 

 illuminating apparatus. 



The illumination may be effected either by means of the universally movable 

 mirror, without the use of condensers, or the simplified illuminating apparatus, 

 Nos. 37 and 38, described on p. 34, may be used. 



In using the latter apparatus only central illumination is possible. If 

 oblique light be required, the condenser with iris- diaphragm and their special sli- 

 ding sleeve must be removed.
