 light brown mud

Albatross 11 (p. 83); 14° 38' N, 136' 44' W. 2646 

 fathoms. Red clay; CaC03 = l per cent; fish teeth; 

 few siliceous organisms and small angular miner- 

 al grains; feldspar, glass, augite, magnetite, man- 

 ganese grains; phillipsite. Dark mottled brown in 

 color. Largely "amorphous" clayey matter 



Albatross 12 (p. 83); 12° 07' N, 137° 18' W. 2883 

 fathoms. Radiolarian ooze; CaC03 = l per cent; 

 greater than 30 per cent siliceous organisms, 2 

 per cent glass, feldspar, hornblende; the remain- 

 der "amorphous" clayey matter. Light brown in 

 color

hornblende, and manganese grains. 



Sample 77. Sand grades contain radiolaria, sponge spicules, and fish teeth in addition to abundant manga- 

 nese grains, pumice, plagioclase feldspar (andesine), and pyroxene. 



Sample 78 consists of two volcanic cinders about 1 cm in diameter coated with manganese and cemented 

 together with the same material. 



Sample 79. According to Piggott, the manganese nodule occurring in this sample contains alternating rings 

 of clay and manganese dioxide, but no nucleus of other material. It was not received in La Jolla. Sand 

 grades, large in amount when compared with samples 61 to 77, consist largely of radiolaria, together 

 with diatoms, sponge spicules, arenaceous foraminifera, white (coprolitic?) pellets, manganese grains 

 (containing nuclei of colorless volcanic glass), pumice, and green volcanic rock fragments. 



Sample 80. Sand grades contain, besides radiolaria, numerous large manganese grains, white rod-shaped 

 coprolitic pellets and tubes, 'jray ellipsoidal pellets, fish teeth, sponge spicules, arenaceous foraminifera, 

 very few pelagic foraminifera, olivine, euhedral plagioclase (over 1 mm in diameter), quartz, hornblende, 

 augite, and volcanic scoria.
