to 1500 fathoms, at intervals of 100 fathoms, to complete the series of the previous 
mening. At 2 r.M. the temperature of the sea-surface suddenly rose from 65°*5 to 
7 i -5, showing that the ship had slipped over the eastern edge of the Gulf Stream. 
Owi to the cloudy and somewhat boisterous weather, little difference was observed in 
the appearance of the water. At 8 p.m. the surface temperature reached 73°, while the 
thermometer in the air stood at 64°. A flock of water-rails alighted on the rigging of 
the hip, and several were caught by the sailors ; numerous stormy petrels were about the 
ship. 
Distance from Sandy Hook at noon, 308 miles. Made good 37 miles. Amount of 
current 17 miles, direction N. G5 W.
