Abstract
IN Nature of August 5, 1944 (p. 169), Lord Rayleigh gives a very interesting description of the production of pebbles of regular shape by laboratory abrasion tests. His main conclusion seems to be that pieces of marble of apparently homogeneous texture tend to become oblate or prolate spheroids even though they start from shapes that are roughly cubic or spherical.
