In a recent column in Popular Science Magazine on the Web (www.popsci.com), Carol Hoidra discussed the "digital rectal examination" for prostate cancer screening. (From the "Science" section, select "Between the Quacks".) When I read column's headline, I thought someone had developed a new, computerized test. But as I started to read, I quickly realized that I had forgotten the etymology for the word "digit".
