A PARALLEL GRINDING INSTRUMENT FOR THE INVESTIGATION OF FOSSILS BY SERIAL SECTIONS
1950
A surface grinding instrument, primarily for grinding parallel sections of fossils at exact intervals down to 10 microns, is described and figured. The ac- curacy of the instrument in its application to paleontology is illustrated. Mention is also made of its use in cutting plates from crystals or other substances. It can either be operated by hand on a stationary grinding plate, or be used in conjunction with a mechanically rotated lap.
