[An attempt to unite in one piece of apparatus the most valuable points in 

 Kinne's and Cunning's instruments. It consists of a circular brass plate, 

 on the under side of which is a lever having its fulcrum on the axle of the 

 table. This lever moves two arms which work in slots cut in the plate 

 so that they always approach or recede from the centre in an exactly 

 equal degree. The arms carry on the upper side of the plate two fiat 

 pieces of brass 2 in. in length, which grasp the slide, one of these being 

 fixed at right angles to the slot, and the other pivoted so as to be able to 

 adjust itself to the slide, as in Uunning's instrument.]
