A VANISHING FROG
Cape Town biologists arid medical men are worried about a threatened scarcity of a species of frog which has become extremely valuable to science. This frog, locally called the plantanna, is found only in the natural ponds of the Cape, and so far all attempts to breed it in . captivity have been unsuccessful. It is used in a simple and certain test for pregnancy developed by scientists in the University of Cape Town, South Africa. Since this test gives positive results much earlier than any devised before, there has been a great demand for the frogs both in South Africa and overseas, and the higher price created by the demand has caused the frog to be hunted ia every pond in the Cape Peninsula. Already'••here are signs that the supply is dwindling, and it is feared that, unless someone can find a way of breeding it iQ, captivity, the frog will b» come extinct.
