The use of biological microtomes in sectioning foraminiferal tests makes it possible to cut continuous serial sections from the same specimen for light microscopy and also offers a potential for use in cutting electron microscopy size sections. Epon 812 (mixture B) gives the most satisfactory results, producing smooth sections free of bubbles. The microtome technique is a more rapid, flexible, reliable, and even cheaper method of sectioning than the conventional grinding or the peel method.
