Ross snapper failed to shut, but 

 small sample adhered to jaws 



Good bottom sample

 fathoms. Globigerina ooze, CaC03=45 per cent. 

 Mostly broken pelagic and many benthonic foramin- 

 ifera, gray clay residue containing many fragments 

 of siliceous ogranisms and minute minerals, in- 

 cluding augite, and a little manganese and hematite

 fragments of siliceous organisms, little clay, few 

 minerals

Ross snapper closed, but brought 

 up only small sample. Small 

 particles of volcanic rock in 

 lead weight

 weight on shaft let down on end 

 of 4-mm wire, 50 m below Nan- 

 sen water bottle. When hauled 

 in, Nansen bottle was full of 



Albatross 4723 (p. 75); 10° 14.3' S, 107° 45.5' W. 

 Depth? Globigerina ooze; washed sample, CaC03 

 not determined. Principally pelagic forams, etc., 

 containing few manganese grains, angular augite 

 grains, splinters of volcanic glass 



Albatross 4726 (p. 67); 12°30.1' S, 111° 42.2' W. 

 1700 fathoms. Globigerina ooze, CaC03=68 per 

 cent. Pelagic and few benthonic foraminifera, 

 brown clay residue very rich in manganese and 

 limonite grains. Few remains of diatoms and 

 sponge spicules. Minute mineral particles 



None 



Sample 13. Abundant fragments of radiolarian skeletons and diatom frustules occur in sand grades, in ad- 

 dition to predominant amounts of broken pelagic and benthonic foraminifera; also present are arenaceous 

 foraminifera, echinoid spines, sponge spicules, and brown mica. 



Sample 14. Sand grades contain smaller amounts of remains of siliceous organisms than sample 13, and 

 correspondingly larger amounts of pelagic and some benthonic foraminifera, also present are echinoid 

 spines, gastropod shell, and a few disk-shaped and ellipsoidal pellets. 



Sample 15. Appears to be partly washed. Contains angular cinder of altered basic volcanic rock, 1 cm in 

 longest diameter, coated with manganese; also small fragments of volcanic glass and shells of bryozoa, 

 in addition to predominant amounts of pelagic foraminifera and a few remains of siliceous organisms. 



Sample 16. Sand and coarse silt grades consist almost entirely of unbroken pelagic and a very few ben- 

 thonic foraminifera, together with numerous minute manganese grains less than 0.01 mm in diameter. 

 Diatoms, radiolaria, etc., are scarce.
