The block containing the specimen is turned until the anterior and posterior edges are parallel; as much of the paraffin being removed as is possible. The knife is placed at right angles and with rapid strokes the sections are cut. The edges of the sections cling to each other and long ribbons may be cut. These ribbons should be carefully placed on sheets of toilet paper, carefully numbered and marked, so that the beginning of each series can be determined. The ribbons are divided into lengths convenient for placing on the slide. They are then floated on water and picked up on the slide covered with the glycerin-albumin.
