THE MICROSCOPES OF 1894. 



Fig. 8 shows the highest class of the " Eclipse " stand, made 

 especially for bacteriological and other high-power work. The 

 adjustments are the same as in the preceding forms and the body- 

 tube is graded to millimetres. The stage is of horse-shoe form, 

 thus allowing free access to the sub-stage when focussing. The 

 sub-stage, which has centering screws, is carried on a triangular 

 bar attached to one side of the stage-plate ; the coarse adjust- 

 ment is effected by a spiral movement in the body of the sub-stage ; 

 the fine adjustment is by a milled head at the bottom of the 

 sub-stage bar ; the bar being at the side of the stage allows of the 

 sub-stage being flung in or out of position as required. The 

 triple nose-piece is so arranged that the objectives adapted to them 

 all focus in the same plane. The tail-piece carrying the double 

 mirror is slotted, and can be swung round to allow of the mirror 

 being used for super-stage illumination. 



Leitz' Mechanical Stage. 



This stage requires no description, as our illustration (Fig. 9) 

 shows everything that is needed. By means of a clamping screw, 

 it can readily be fixed to the stand of the microscope. The slide 

 is easily retained in position by a jointed curved arm. The finders 

 are so placed that markings can quickly be found.
