The block is trimmed in a pyramidal form so that it will be rigid. Take particular pains that the opposite faces at the end of the block are parallel, and all the corners right angles. § 444.

Making Paraffin Sections.—Put the paraffin block or the metal holder in the clamp of the microtome. Arrange the block so that one side of the pyramidal end is parallel with the edge of the knife, then tighten the clamp, and if an automatic microtome is used make sure that the section knife is also tightly clamped by the proper set screws. It is well to have the knife lean slightly toward the paraffin block (Fig. 239).. Fig. 233.
