Institute of Mental Health, Section on Technical Development, Bethesda, Maryland Obtaining thin sections for electron microscopic study from tissue regions that must first be identified in the light microscope is often a difficult and timeconsuming problem. Recently, Woodcock & Bell (1967) described a method for mounting 4-pm epoxy sections for subsequent ultramicrotomy. Their device has been modified by substituting a cam for the individual spring mounts that hold the epoxy slugs on which the 4-pm sections are placed and polymerized. The device and its separate parts are shown in Figs. 1 and 2. The Fig. 1. epoxy-resin slugs (Rockwell et al., 1966), are positioned in the slug holder with the rotating cam in its low position. A tissue section, 2-10 pm in thickness, is placed in a small drop of fresh epoxy-resin mixture on top of each slug. A 1 x 3 in. microscope glass slide covered with aluminium foil is held in place by the finger springs. The hardened epoxy resin will not stick to the foil. The cam, with a vertical displacement of 2.4 mm, is turned clockwise to the stop
