In the EDITORIAL published under this title in the Feb 28 issue (219:1206), two errors occurred. In the third paragraph, lines four and five, the terms "of mass" and "in one second of time" should be deleted from the definition of the joule. In line 18 of the same paragraph, the equivalency factor should read 4.185, not 4,185.5 as published.
