SUMMARY OF RESULTS. 
Ill 
At 7 a.m. sounded in 325 fathoms, Hard Ground, bottom temperature 52°'0 
(Station Ia.), and at 9 a.m. in 730 fathoms, Hard Ground, bottom temperature 49°‘5 
(Station Ib.). At 11 a.m. sounded in 950 fathoms, Hard Ground (Station Jo.), but the 
line carried away owing to a bad splice. At 11.30 a.m. put dredge over in about 1000 
fathoms ; it came up without mud at 4 p.m., having apparently not been on the bottom, 
but contained one small fish, some small Crustacea, and Pteropoda. Between Vigo Bay 
and Burlings Islands the tow-net was used. At night the sea showed luminosity duo 
apparently to small Crustacea. 
Position at noon, about 40 miles west of Cape Mondego ; Burlings Islands distant 59 
miles. Made good 86 miles. Amount of current 12 miles, direction N. 75° E. 
Surface Organisms. — Crustacea and Pteropoda were obtained in the surface tow-net. 
Station Id. (Sounding 5), Cape Finisterre to Lisbon (see Chart 3). 
January 2, 1873 ; lat. 39° 55 ' N., long. 10° 5' W. 
Temperature of air at noon, 57° ’3 ; mean for the day, 56° ’ 7 . 
Temperature of water at surface, 57° 0. 
Depth, 1975 fathoms. 
At 9 a.m. sounded in 1975 fathoms, but the line was carried away, owing to a bad 
splice, making the third sounding line and third thermometer which have been lost. 
At 10.30 a.m. lowered dredge in about 2000 fathoms, and commenced heaving in at 
2 p.m. At 9.20 p.m. the dredge-rope was carried away, about 2000 fathoms of line being 
lost along with the dredge, which probably fouled something at the bottom, as there 
was a heavy strain on the line, and only a fathom or two could be hauled ir at a time. 
Position at noon, about 40 miles N.W. of Burlings Islands, coast of Portugal. Made 
good 30 miles. Amount of current 7 miles, direction S. 56' E. 
The Challenger remained at anchor off Lisbon from 1 p.m. on January 3 till 5 p.m. 
on January 12, 1873.
