Density at 60° F. at surface, 1 ‘02625 ; bottom, 1 '02595. 
Depth, 2020 fathoms; deposit, Blue Mud, containing 27‘75 per cent, of carbonate 
of lime (see Murray and Renard, Deep-Sea Deposits Chall. Exp.). 
At 7,30 a.m. stopped to sound and dredge. At 8 a.m. sounded in 2020 fathoms. 
At 9 a.m. sent jolly-boat to collect surface animals. At 10 a.m. put over dredge, and 
veered 2900 fathoms. At 1.55 p.m. commenced heaving in dredge, but the dredge rope 
parted at 1700 fathoms, the dredge being 300 fathoms from the bottom ; at the time of 
the accident no undue strain on the rope was observed. Obtained a series of tempera- 
tures at intervals of 100 fathoms down to 1500 fathoms. Obtained samples of water 
from 250 and 500 fathoms for analysis. 
Distance from Bermuda at noon, 550 miles. Made good 55 miles. Amount of 
current 10 miles, direction S. 33° E. 
Surface Organisms. — Willemoes-Suhm writes : “ The iridescent Snphirina , found so 
often in the eastern part of the Atlantic, was, with some other species of the same genus, 
very abundant at the surface.. Salpse and Siphonophor.se- also abound, and some Cteno- 
pliorse, Sagitta, and Heteropods were also present,” 
Station 52 (Sounding 110), Halifax to Bermuda (see Chart 9 and Diagram 2).
