lower in 1912 than in 1910, and it is obvious that the upper boundary 

 of the cold deep-water with temperature below o C. was lying considerably 

 higher on July 3oth 1912 than on July iyth 1910 (see Fig. 17 & 18). It 

 seems, however, as if the salinities found in 1910 for the depths between 

 400 and 800 metres (see Fig. 17) are sometimes too high; for it is hardly 

 probable that at 800 metres, with a temperature of 0.51 C., the salinity 

 could be as high as 34.96 % ; it has probably been not much above 

 34.92 or 34.91 /oo- 



The temperatures at 300 and 500 metres are lower at our Stat. 17 

 than at the same depths at our Stat. 56, to the south, which has an 

 exactly similar position just outside the edge of the continental shelf west 

 of South Cape, at a depth of i 020 metres. The salinity of the water is also 

 decreased on its way northward, as might be expected (see Figs. 8, 9, n, 12). 



The mean temperature of the water between 50 and 450 metres, 

 computed from the temperatures at 100, 200, 300 and 400 metres, was
