The Inland Waters of South Africa

Abstract

IN view of the forthcoming visit of the British Association to South Africa, we should like to direct the attention of biologists to certain remarkable inland waters occurring in that country. Throughout the southern half of the Transvaal, as well as in many other parts of South and South-west Africa, are found shallow saucer—like depressions of various sizes which may be filled temporarily or permanently with water. These pans have been ably described by Rogers,¹ and are generally admitted to be the result of wind erosion at a time when the climate of the country was drier than it is at present, although Passarge² considers them to have been the result of ‘zoogenous’ erosion in the Kalahari.
