Richardson announced a chemical test that requires no animals, takes only half an hour at most, is 100% accurate, and works within three weeks after conception...

It is based on the long-known fact that the amount of the female hormone, estrone, in the urine increases greatly after conception. First, Dr. Richardson puts a specimen of urine in a special double-barreled test tube he invented. Then he gets rid of other hormones (progesterone derivatives), which might interfere with the test, by mixing in chloroform and sodium hydroxide. The fluid containing estrone rises to the top. This fluid is put in two other test tubes and a different chemical...
