Correction
It was erroneously reported in Constance Holden's article "Animal regulations: So far, so good" (News & Comment, 13 Nov., p. 880) that animal activists broke in and stole 15 monkeys in a 1981 raid on the laboratory of Edward Taub in Silver Spring, Maryland. In fact, 17 animals were seized by Montgomery County police, who had a warrant, in response to allegations by activists, including one who was employed at the lab.
