As a rule we supply a small incandescent lamp, using a pressure of 7 or 

 8 volts with a current of I ampere, and 3 spare lamps. For feeding the lamp 

 it is best to use accumulators. If connection be established with an existing 

 electrical supply system, sufficient resistance must be provided. 



Small incandescent lamps of 12 volt pressure can also be supplied if desired. 



The double tube with its illuminator attachment is movable within the 

 vertical plane by means of a joint which works on a horizontal axis and may 

 be clamped in any desired position, while a vertical axis admits of the opposite 

 movement. The microscope is elevated or depressed by means of rack and pinion 

 and a second similar movement effects changes of position from front to rear.

From a suggestion of Prof. GULLSTRAND we provide, when requested, 

 Stand X c with an arrangement for illuminating the object laterally, No. 9810; for 

 this purpose the illuminating apparatus No. 43 is made slidable in an arc. The 

 price of the stand with this adaption is increased by 30 Marks. 



Subsequent transformation of Stand X No. 98 is possible so as to embody 

 GULLSTRAND' s device for lateral illumination; it entails, however, the simul- 

 taneous ordering of a new cabinet, costing 22 Marks, since any alteration of 

 the stand will not allow its further accommodation in the cabinet previously 

 supplied with the simple Stand X c . 



Stand X resting upon a massive tripod foot is most advantageously employed 

 when set upon the sole-plate with chin-rest No 9820. At the suggestion of 

 Prof. EVERSBUSCH this sole-plate is made so as to be movable in two directions 

 at right angles to each other. The sole-plate with chin-rest can also be employed 

 with Stand X c No. 9810 as with Stand X No. 98.
