词汇 9944 percent pure
词源
99.44 percent pure. This bit of advertising hype for ivory soap is often used jokingly to describe anything pure. The New York Times (5/22/94) reported that: “A Procter & Gamble archi- vist, Edward Rider, says that although the soap’s history is shrouded in myth, the best source for the number is an analysis done Dec. 14, 1882, by a New York City chemist, W. M. Habir- shaw, who found the soap to be 72.53 percent ‘fatty anhydrides,’ 9.28 percent ‘soda combined’ and 17.63 percent ‘water by dif- ference.’ ” If you add up the numbers you get 99.44 percent. And the first known ad to use this figure appeared a week later.
