A cross-feed rotarv milling table, which is horizontally mounted, serves as the specimen stage. The section holder is placed on top of this unit. The section holder is made of a one-half inch brass block with a spring clamp in a dust enclosure box ( Fig. 4). J lori/.ontal motion of the table (from left to right, or right to left) is effected bv means of the shunt motor. The crank wheels for the cross-feed and table rotation are controlled manually.
