Station 41 
At 7 a.m. proceeded under steam to sound. Blowing hard, with a heav}^ swell. At- 
tempted to take a series of temperatures, but could not succeed. At 7.50 a.m. the 
starboard wheel-rope was carried away, and the necessary repairs caused some delay. 
Later in the day swell moderated, and at 3.40 p.m. proceeded to obtain serial tempera- 
tures down to 650 fathoms. 
Distance from Sandy Hook at noon, 324 miles. Made good 101 miles. Amount of 
current 12 miles, direction N. 40° W.

Density at 60° F. at surface, 1 ’02695 ; bottom, 1 '02668. 
Depth, 2425 fathoms ; deposit, Blue Mud, containing 24’34 per cent, of carbonate 
of lime (see Murray and Renard, Deep-Sea Deposits Chall. Exp.). 
At 6.30 a.m. shortened sail, and got up steam to sound. At 8 a.m. sounded in 2425 
fathoms. Sent down water-bottle and two thermometers. The water-bottle seemed to 
have fallen on its side into the mud before closing, as it contained a considerable quan- 
tity of the upper layer of mud. The swell was still heavy, and sounding operations were 
carried on with some difficulty. Serial temperatures were, however, obtained from 900
