110 THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 
WASHED SAMPLES. 
Station 24, 14th September, 1899. 
Lat. 8° 14’ S.; long. 139° 46’ W.; depth, 1040 fathoms. 
GLOBIGERINA OOZE: very little material, consisting of the usual pelagic 
Foraminifera, otoliths, etc., with fragments of manganese nodules, and many 
small grains of manganese. 
Station 25, 14th September, 1899. 
Lat. 8° 48"S.; long. 139° 48’ W.; depth, 830 fathoms. 
The material consists of two manganese nodules with palagonitic nuclei, 
the larger 25 mm. in maximum diameter, along with smaller particles 
and grains of manganese, mixed with a few pelagic and bottom-living 
Foraminifera. 
Station 26, 14th September, 1899. 
Lat. 8° 52’ S.; long. 139° 52’ W.; depth, 1173 fathoms. 
PTEROPOD OOZE or CORAL MUD: the material does not apparently rep- 
resent the deposit én situ, being incoherent and fine-grained, consisting of 
Pteropod fragments, pelagic and bottom-living Foraminifera, Echinoid spines, 
Ostracodes, Polyzoa, Coral fragments, small shells Mollusc, Serpuda, coccoliths ; 
Diatoms, Sponge spicules; with palagonite, much oligoclase (partly decom- 
posed), a little olivine, a bright red mineral, probably decomposition pro- 
duct of olivine, and volcanic glass. 
Station 27, 15th September, 1899. 
Lat. 9° 1’ S.; long. 140° 4’ W.; depth, 687 fathoms. 
PTEROPOD OOZE or VOLCANIC MUD: the material has the appearance of 
having been partly washed, is granular and of a dirty gray color, contains small 
Pteropods, pelagic and bottom-living Foraminifera, Echinoid spines, Bryozoa, 
Ostracodes; Sponge spicules, Diatoms; anda great amount of mineral parti- 
cles (probably 30 per cent of the sample), consisting principally of volcanic 
glass, felspar, and magnetite. Although apparently washed, a small portion 
was submitted to analysis, and gave 56.4 per cent of calcium carbonate.
