100. Now on comparing these two series of Soundings with the Bottom- 

 soundings taken at different parts of the Cold area, the accordance is found 

 to be extremely close, no difference of more than a degree being found any- 

 where at depths greater than 300 fathoms. It is worthy of note that at the 

 shallower depths of from 114 to 167 fathoms (Nos. CO, (51, 62), the bottom- 

 temperatures correspond more closely to the temperatures of the same depths 

 in Series 64 than to those of Series 52, the cold water coming nearer to 

 the surface ; and this was still more remarkably the case with No. ix., the 

 sounding obtained last year on a bank at 1/0 fathoms ( c Lightning' Report, 

 §13). On referring to the Chart it will be found that these four stations
