SUMMARY OF RESULTS. 
137 
Density of water at 60° F. at surface, 1 ’02730 ; bottom, 1 ’02650. 
Depth, 1890 fathoms; deposit,. Globigerina Ooze, containing 50 per cent, of 
carbonate of lime (see Murray and Renard, Deep-Sea Deposits Chall. Exp.). 
At 8 a.m. sounded in 1890 fathoms, when a water-bottle was sent down for the 
first time with the sounding lead. At 9 a.m. the dredge was put over At noon 
Siemens’ thermometric apparatus was tried for the first time down to a depth of 1000 
fathoms, with fair results. At 1.30 p.m. commenced to haul in dredge, and at 2 p.m. 
obtained temperatures at various depths by means of thermometers and Siemens’ apparatus. 
The dredge came up empty at 4 p.m., having probably fouled the rope in paying out. 
Position, at noon about 40 nautical miles south of the southern extremity of Tenerife 
Island; Sombrero Island distant 2.620 miles. Made good 76 miles. Amount of current 
8 miles, direction S. 75° W,.

rinella], Copilia, Hyperia, Phronima, Mysis, Zoese ; Atlanta, Firoloida ; Styliola,

Surface Organisms. — The following are recorded in the note-books as having 
been captured in the surface tow-nets, which skimmed the surface only as the vessel was 
moving fast : — Siphon ophorae, Copepods, Idothea, Lucifer, Phyllosoma, many Zoese, 
Cavolinia, Styliola, two empty shells of Spirula. 
Willemoes-Suhm writes : “I found a young specimen belonging to the Saphirinae 
with two long pigment bodies, but only one large cornea ; perhaps it may divide later, 
or it may be that this is a species in which the cornea is undivided. We found for the 
first time the singular genus Lucifer, which is referred by Claus to the Decapods, and 
by Gerstaecker to a family intermediate between the Squill inse and the Schizopods." 
Station 2 (Sounding 46), Tenerife to Sombrero (see Chart 6 and Diagram 1). 
February 17, 1873; lat. 25° 52' N., long. 19° 22 ' W. 
Temperature of air at noon, 65' ’3 ; mean for the day, 64°’2.
