At 1.45 p.M. shortened and furled sails, and proceeded under steam to sound. At 
2.30 P.M. sounded in 1475 fathoms. The sounding-tube contained only a few Pteropod 
shells, Foraminifera, and small particles of peroxide of manganese. On the outside of 
the tube were several black streaks due to peroxide of manganese. Took serial 
temperatures down to 1000 fathoms. At 4.30 p.m. completed temperatures and made 
all plain sail.
