sheets of light caused by Noctiluca [ = Pyrocystis ] or dead fish matter on the surface. Station 96 
When held in the hand, the specimens showed well the breaking out of light all over 
the body, from irritation, or rather considerable shock, as a blow from the finger, at one 
end ; the light shows first at the place struck.” 
Station 97 (Sounding 168), St. Vincent to St. Paul’s Rocks (see Chart 12 and Station 97.

Depth, 2575 fathoms; deposit, Globigerina Ooze, containing 30'15 per cent, of 
carbonate of lime (see Murray and Renard, Deep-Sea Deposits Chalk Exp.). 
At 9 a.m. shortened sails and stopped to sound. Sounded in 2575 fathoms. Took 
serial temperatures down to 1500 fathoms. Obtained sample of water from bottom for 
analysis. At 12.15 p.m. completed temperatures, and at 1.55 p.m. made all plain sail. In 
the evening the sea was remarkably phosphorescent. 
Distance at noon from St. Paul’s Rocks, 780 miles. Made good 102 miles. Amount 
of current 26 miles, direction S. 67° E.
