Attention is particularly invited to the position of a salient formed 

 by both the 4° isothern and the 34.8%o isohaline (figs. 54 and 

 55) off southern Labrador in the vicinity of latitude 55° K, longi- 

 tude 50° W. The distribution of temperature and salinity, corre- 

 sponding to the circulation (fig. 47), indicates a convergence of cool, 

 low-salinity surface layers from the Labrador slope with the inshore
