If ethionine or CCl4 was given simultaneously with urethan or phenobarbital, the normally observed shortening response was blocked. If, however, ethionine or CCl4 was given 24 hours after the urethan or phenobarbital, the response was not blocked. These data are interpreted to indicate that the urethan and phenobarbital responses may be due to enzyme induction. These effects were produced with doses of ethionine and CCl4 which had no effect on normal sleeping time and bromsulfalein retention.
