in the former than in the latter. Deeper down the difference 

 becomes less, and at 1,000 metres (545 fathoms) there was only a 

 difference of one or two tenths of a degree. 



Fig. 10 shows a corresponding difference in salinities; in 

 the first 200 metres below the surface the water was about

 Benguela Current. Both these currents are confined to the upper 

 waters; the former probably goes down to a depth of about 

 1,000 metres (545 fathoms), while the latter does not reach a depth 

 of much more than 500 metres. Below the two currents the
