LIST OF STATIONS 19 



A small tube of very refractory pale-grey mud. Residue aggregates of fine sand, Radiolaria and 

 diatoms {Coscinodiscus) bound together with filamentous diatoms. Sponge spicules and Foraminifera 

 almost entirely absent. 



342. (Deposit No. 28.) 



30. xi. 03. 56° 54' S, 56° 24' W. (In the Scotia Sea.) Sounding, 1946 fathoms. 



Globigerina Ooze. (Globigerina Ooze.) 



Only a few cc. of hard and refractory ooze. Residue of mud aggregates, Globigerinae and fine 

 sand. 



This station was not worked out, the amount of material being insufficient. 



387. (Deposit No. 30.) 



26. ii. 04. 65° 59' S, 33° 6' W. Sounding, 2625 fathoms. 

 Glacial Clay. (Blue Mud approximating to Red Clay.) 



About 300 cc. of very tenacious blue-grey clay. Refractory — it was dried twice and finally 

 broke down with hot soda. Only i cc. residue left on the 150-mesh silk sieve, consisting of angular 

 sand grains of all sizes and many small crystals of gypsum. Foraminifera almost absent, only five 

 arenaceous species being listed. Radiolaria and sponge spicules very rare. No diatoms seen. Crystals 

 of hydrated calcium oxalate present in very small numbers. The finest residue consisted of refractory 

 clay aggregates. 



391. (Deposit No. 31.) 



27. ii. 04. 66° 14' S, 31° 18' W. Sounding, 2630 fathoms. 

 Glacial Clay. (Blue Mud approximating to Red Clay.) 



About 200 cc. of tenacious grey clay which left only i cc. residue on the 150-mesh silk sieve. 

 Sand grains of all sizes, some Radiolaria, a few sponge spicules and fragments of three species of 

 arenaceous Foraminifera. Crystals of gypsum frequent but small. 



394. (Deposit No. 32.) 



28. ii. 04. 66° 43' S, 27° 55' W. Sounding, 2685 fathoms. 

 Glacial Clay. (Blue Mud approximating to Red Clay.) 



About 150 cc. of highly refractory slate-blue clay showing signs of lamination. After protracted 

 treatment it was at last broken down and yielded about 3 cc. of residue, flakes of clay, a few sand 

 grains and Radiolaria. No diatoms or sponge spicules. Foraminifera almost absent, four arenaceous 

 species only listed. 



406. (Deposit No. 33.) 



3. iii. 04. 72° 18' S, 17° 59' W. Sounding, 1131 fathoms. 



Glacial Mud. (Blue Mud.) 



About 300 cc. of dark slate-coloured mud, granular and laminated, giving a residue of angular 

 sand grains of all sizes, mostly very small but ranging up to j in. in diameter. Many sponge spicules 

 and large and small Radiolaria ; a few small diatoms were found in the residue retained on the 

 200-mesh silk sieve. Foraminifera very rare, but over 20 species were listed, including some small 

 specimens of Milianunina arenacea, the only record of the genus in the Weddell Sea. 



A few minute fossils were obtained from this sounding which are more fully referred to on p. 11. 



416. (Deposit No. 37.) 



17. iii. 04. 71° 22' S, 18° 15' W. Sounding, 2370 fathoms. 



Glacial Mud. (Blue Mud.) 



About 300 cc. of dark slate-blue clay with sand left a residue of 35 cc. fine angular sand with 

 much glauconite. Hardly any Radiolaria or sponge spicules, and no diatoms. The residue was floated 

 with carbon-tetrachloride, but without results other than four specimens of Haplophragmoides 

 siibglobosus, three of Cyclamnmia pusilhi and single specimens, more or less fragmentar>', of three 

 other species. A few minute fossils were found (see p. 11).
