The illumination is obtained by means of the universally movable mirror. 

 The sliding sleeve fixed below the stage by a bayonet joint is not only adapted 

 for the cylinder-diaphragm, No. 39, and the iris-cylinder diaphragm, No. 40, but 

 also the illuminating apparatus, No. 41 (see p. 34), may be inserted. 



Owing to its compactness Stand Vl a is particulary suitable for a Travelling 



Microscope. 



We supply the stand, if specially ordered, enclosed in a small leather or 

 canvas case with shoulder-sling instead of the mahogany cabinet. The total 

 weight of the stand with complete optical equipment (3 objectives, 3 oculars) 

 and the most indispensable specimen utensils, also including the case, amounts 

 to 4 kg (about 9 Ibs.).
