THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 71 
Fine Washings (82 per cent), dark-brown flocculent clay, characterized 
by a great abundance of minute crystals of phillipsite, with one or two 
minute manganese grains. 
No. 52. Station 4534,* 9th February, 1905. 
Lat. 13° 51’S.; long. 126° 53.5’ W.; depth, 2185 fathoms. 
GLOBIGERINA OOZE: light brown, slightly coherent, not sticky. 
CALCIUM CARBONATE: 72.72 per cent, pelagic Foraminifera, with a few 
bottom-living forms (Rotaha). 
Resipur: 27.28 per cent; no clastic minerals nor siliceous organisms 
observed ; the residue consists of chocolate-brown flocculent clayey matter, 
containing numerous very small crystals of phillipsite and a few minute 
manganese grains.

shells being more or less fragmentary. 
ResipuE: 22.74 per cent: — 
Siliceous Organisms (traces), fragments of arenaceous Foraminifera and 
of Radiolaria, with Diatoms, and a few Sponge spicules.

Fine Washings (22.74 per cent), brown flocculent clay, containing 
many minute manganese grains and other mineral particles much too small 
to be identified, and fragments of siliceous organisms.
