The two forms of * BERNHARD's drawing tables satisfy in a perfect 

 manner the twofold requirement of being adapted for regulating the height of 

 the drawing surface above the work table and for varying its degree of inclina- 

 tion to the horizontal plane. (See "Zeitschr. f. wiss. Mikrosk.", vol. IX, 1892, 

 pp. 439445 and vol. XI, 1894, pp. 298301.) 



With tables of above pattern the drawing surface may be raised to a 

 height of 17 cm (6 3 /4 in.) and inclined at an angle of about 35. The microscope 

 is clamped to the base of the drawing table, and arm-rests are provided in order 

 to give the operator's hands the steadiest possible position. 



The table is supplied either for use with the microscope in the upright 

 position or with an arrangement for inclining the microscope together with 

 the table. (Fig. 49.)
