No. 33. Station 4707, 28th December, 1904. 
Lat. 12° 33.2) S.; long. 97° 42’ W.; depth, 2120 fathoms. 
GLOBIGERINA OOZE: olive-brown, plastic; reddish-gray and slightly 
coherent when dried. 
CaLctum CARBONATE: 71.01 per cent, principally pelagic Foraminifera, 
with a few bottom-living forms (Béloculina). 
ResipuE: 28.99 per cent, earthy brown : — 
Siliceous Organisms (traces), spherical Radiolaria, Sponge spicules, and 
a few arenaceous Foraminifera. 
Minerals (traces); the few particles present are angular, and have a 
mean diameter a little under 0.1 mm.; plagioclase, augite, and manganese 
grains may be recognized, with particles of a decomposed ferro-magnesian 
mineral. 
Fine Washings (28.99 per cent), very flocculent, chocolate-brown clay 
(very easily attacked by hydrochloric acid, leaving a white residue), with 
a few fragments of minerals and siliceous organisms. 
No. 34. Station 4709, 30th December, 1904. 
Lat. 10° 15.2'S.; long. 95° 40.8’ W.; depth, 2035 fathoms. 
GLOBIGERINA OOZE: there are two samples,—one pure white and 
chalky, the other light gray, with a reddish tinge. 
CALCIUM CARBONATE: 78.10 per cent. This percentage is the mean of 
analyses of the two samples, the white sample giving 81.20 per cent, and the 
gray sample 75.00 per cent; shells of pelagic Foraminifera and their com- 
minuted fragments. 
Resipue: 21.90 per cent, chocolate-brown in the case of the darker ooze, 
yellowish in the case of the white one. The residue is easily attacked by
