SUMMARY OF RESULTS. 
1227 
Hastigerina, PulvmuUna menardii, Acanthometrse, Polycystinse, and compound 
Radiolaria, several forms of Siphonophorm, Sagitta, Tomopteris, Alciopa, Planarian 
larvae, JEvadne, Copilia and other Copepods, Lucifer, Sergestes and other Decapod larvae, 
Atlanta, several forms of Pteropods and larvae, and small fishes. The tow-nets at the 
weights came up wound round the line, but contained a few Challengeridae and some 
living and dead Foraminifera. Some of the Globigerinse were surrounded with a circle 
of sarcode, in which were entangled a great many Coccospheres, Rhabdospheres, 
Peridinium, and minute Infusorians. 
Station 336 (Sounding 486), Tristan da Cunha to Ascension Island (see Chart 16

Depth, 1890 fathoms ; 
deposit, Globigerina Ooze, containing 7 9 '02 
carbonate of lime (see Murray and Renard, Deep-Sea Deposits Chall. Exp.). 
At 5 A.M. shortened and furled sails, and proceeded under steam to sound. At 6 a.m. 
sounded in 1890 fathoms. Only a small quantity of deposit came up in the sounding- 
tube. Obtained serial temperatures down to 1500 fathoms. At 10.30 a.m. completed 
observations and made sail to a strong south-easter, the ship going 10|- knots at noon.
