increase of pressure, and this has since been confirmed by experiments made by Professor 
Taft, 
Around the Society Islands the saltest water of the Pacific is found ; it is here 
only that the density exceeds P0270, and nowhere does it reach P0275. The great 
bulk of the water in this Ocean has a density under l - 0260. The very low surface 
specific gravity observed in lat. 9° N. is purely superficial, and is characteristic of the 
Counter Equatorial Current. As in the Atlantic, the minimum specific gravity is found 
usually at a depth of about 1000 fathoms, but in the Pacific light water approaches 
the Equator from both sides at the bottom, whilst in the Atlantic it comes in a marked 
degree only from the south ; and consequently in the^ North Pacific the mean specific
