Those of you who have AOL can get the December 1995 issue of Scientific American by "go"ing to "scientific american" Those of you without, can access the text alone through my page: http://www.clark.net/pub/activist/bfpage/bfpage.html. Go to "other links of interest" and link from there. Or, you can go directly to the article at: http://www.clark.net/pub/activist/bfpage/scientific_american.html Rachael Hamlet
