I looked up 'embryo' and 'fetus' in Webster's New World Dictionary, Third College Edition: embryo, "...in humans, from conception to about the eighth week: see FETUS..." fetus,"..."in humans, from about the eighth week after conception until birth: see EMBRYO". For sure, not the same. Those of you who worked so hard on the Udall Bill: {{{{{{{{thank you}}}}}}} Liz
