THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 59 
CALCIUM CARBONATE: 11.80 per cent, principally pelagic Foraminifera, 
many broken; with a good many Fishes’ teeth, and a few bottom-living 
Foraminifera (Lotalia). 
Resipue: 88.20 per cent, mostly “fine washings,” the larger washings 
from 12 grams of clay amounting to only a few centigrams : — 
Siliceous Organisms (traces), very few Sponge spicules. 
Minerals (traces); the rare particles present are angular, and only very 
few attain a diameter of 0.1 mm.; most of them belong to some decomposed 
basic mineral, and are present as greenish, nearly opaque, flakes ; plagioclase, 
augite, manganese grains, and phillipsite (in the form of isolated crystals, 
not in clusters) may be recognized. 
Fine Washings (88.20 per cent), chocolate-brown flocculent clay, the 
dark color being due to numerous very minute grains of manganese; a few 
small crystals of phillipsite and other minute mineral particles observed. 
No. 31. Station 4703, 27th December, 1904. 
Lat. 17° 18.6’ S.; long. 100° 52.3’ W.; depth, 2228 fathoms. 
GLOBIGERINA OOZE: earthy-brown, plastic, but not sticky; the dried 
lumps are only slightly coherent; a few Foraminifera visible to the naked 
eye. 
CALCIUM CARBONATE: 40.92 per cent, pelagic Foraminifera (mostly 
broken), Fishes’ teeth, a few small Echinoid spines, and various bottom-living 
Foraminifera. 
ResipuE: 59.08 per cent : — 
Siliceous Organisms (0 per cent). 
Minerals (traces); the principal mineral is phillipsite in crystals, 0.03 mm. 
in length, and always isolated; a few particles, angular and 0.06 mm. in 
mean diameter, belonging to a decomposed mineral, are nearly opaque, 
brown, and have lost all birefringence ; manganese grains are numerous, but 
very small. 
Fine Washings (59.08 per cent), flocculent clay, colored brown by 
minute manganese grains, with a few very small mineral particles. 
No. 32. Station 4705, 28th December, 1904. 
Lat. 15° 5.3’ S.; long. 99° 19’ W.; depth, 2031 fathoms. 
GLOBIGERINA OOZE: light gray, in places yellowish, chalky. 
CALCIUM CARBONATE: 78.62 per cent, a great variety of pelagic and
