After Defant, 1936. and velocity, for sometimes, between October and June, but principally in March, April, and May, the direction of the current is completely reversed, and is found setting southward, and sometimes south-eastward.' Defant (1936) has analysed the Dutch current observations, and meaned them for four quarters into one degree areas (i° longitude by i° latitude), and concludes from his analysis (Fig. 6): Ein Blick auf diese Stromfelder lehrt, dass das Charakteristische in ihnen die in alien Monaten wieder mit nicht zu iiberbietender Deutlichkeit auftretende einseitige Divergenzlinie ist; sie lauft nordnordwestwarts langs der Kiiste Siidwestafrikas von etwa 300 bis iiber 200 siidl. Br.; im Siiden ist ihr Abstand von der Kiiste rund 160 sm, im Norden 300-350 sm. Das Gebiet ostwarts dieser Divergenzlinie, das ist gleichzeitig das Gebiet des Kontinental- abfalles und des Schelfes, hat eine Stromung nordnordwestwarts, also parallel der Diskontinuitatslinie und mehr oder minder auch parallel dem allgemeinen Kustenverlauf. Das Gebiet westwarts der Divergenzlinie hat im wesentlichen einen Strom nach Westen. This interpretation of Defant's appears to correspond fairly well with the data in the possession of the Meteorological Office, the position of Defant's current being similar to th
