Abstract
STARTING in November 1948, a series of tests1 for pregnancy were performed using the native male toad, Bufo melanostictus Schneid. Specimens of urine from women pregnant from six weeks to seven months were used. In each series, two or more experimental toads were used. Controls in each series were injected with urine from a woman known not to be pregnant.
