Upon the sliaft (d) vests tlio table (g) and is attaclied to (J 

 hy a large pin wliicli is fitted iuto the upper portion of (J. The 

 tal)lt' is cdamped fast by the screw (L) and raay bc rotated in 

 tlie long- axis of d by loosening the screw (L). Attached to the 

 table {g) are the camera support slide (i) and the illuminating 

 bench (Ä'). Tlie camera support consists of a i)late which slides 

 in a dove tail slot in the table {g) and is clamped by the screw 

 (/). Rising from {i) is the camera support {m). The arrangement 

 of the camera upon this support is the device of Winkel and has 

 already been described. 



The camera is supported by two parallel rails swinging upon 

 a pivot, which in turn is supported by a block (?i) which may be 



m 1 



adjusted in the vertical upon the support {m). The position of the 

 camera may be altered from vertioal to horizontal and may be 

 placed at any intermediate angle desired. 



The entire camera in any position may be adjusted to the 

 lieight of the microscope by raising and loweriug the supporting 

 block (n) on {m). Beneath the support {n) is a second supporting 

 block (o). This is usually clamped fast after the camera has been 

 adjusted, and the screw of the block (?«) may be loosened and the 

 apparatus swung clear of the microscope about the support {m). 



A stop adjustment between m and o indicates the proper 

 position of the camera when swung back. The connection between 

 the microscope and the camera is accomplished by meaus of the 

 usual double coUar. In this case the smaller ring is composed of 

 two , the outer sliding over the inner and having an Archimedes
