In Reply In response to our editorial1 on their article,2 Richardson and colleagues have submitted 3 specific comments. We agree with some of their points, and we appreciate their identification of statements in our editorial1 that were not as clear as we had intended.

As to the first point by Richardson and colleagues, we acknowledge that on the second page of the editorial, in beginning to discuss their findings, we referred to dichlorodiphenyldichloroethylene (DDE) levels in brains when, in fact, we were discussing levels in serum.
