CuAP. XII.] OCEAX CURRENTS. 145 



I do not find that the analogous divergence south- 

 wards has been noticed, and it is only by means 

 of observations which accord with the course of its 

 counter- currents that I find any recorded trace of its 

 existence. And, as regards the coasts, the stream 

 which runs southwards from the Arctic regions on the 

 west of the ocean shows a remarkably constant ten- 

 dency to keep inshore during the whole of its course 

 from the east coast of Greenland to the coast of 

 Florida : it being, in fact, forced inshore both by the 

 a?tion resulting from axial rotation and by that 

 resulting from onward motion. But the stream from 

 the Antarctic regions, analogous, as far as axial rota- 

 tion is concerned, to the Arctic stream just described, 

 appears to be drawn from the direction of Cape Horn 

 eastwards towards mid-ocean, though the sole action 

 of axial rotation would tend to throw it inshore from 

 Cape Horn, and cause it to run northwards along 

 the east coast of South America ^ in the same manner 

 as that m which it tends to throw the Arctic stream 

 inshore against the coast of North America ; instead 

 of which the stream from Cape Horn bears eastwards, 

 leaving a great eddy to run southwards between it 

 and the shore. 



' The ' Challenger ' explorations have shown the existence of 

 a greater mass of cold water moving northwards Ijelow the surface 

 in that locality than was apparent in 1868, when the above was 

 published. But the corresponding stream in the northern hemi- 

 sphere is much more apparent on the surface, as stated in the text 

 above, which those explorations corroborate.
