SUMMARY OF RESULTS. 
817 
Density at 60° F. at surface, 1 ‘02571 ; bottom, 1 ‘02546. 
Depth, 2225 fathoms; deposit, Blue Mud, containing 14‘63 per cent, of carbonate 
of lime (see Murray and Renard, Deep-Sea Deposits Chall. Exp.). 
At 8 A.M. shortened and furled sail, and proceeded under steam. At 9 a.m. sounded 
in 2225 fathoms. Obtained serial temperatures down to 400 fathoms. The carbonic 
acid was determined in bottom water, and amounted to 24 ‘3 milligrammes per 
litre. Position of sounding about 31 miles due W. of Point Gooder (Mindanao), 
and about 35 miles S.S.W. of Station 202. At 10.50 a.m. completed observations 
and made all plain sail, A few boobies {Sula) were observed skimming over the 
surface of the water. 
I 
Sangboys Island distant at noon, 64 miles. Made good 107 miles. Amount of 
current 14 miles, direction S. 69° W. 
Tw’o Hexactinellid Sponges (Holascus ridleyi, n.g., n.sp., and Hyalonema gracile, 
n.sp.) are recorded in error by Schulze (Zool. pt, 53) from this Station; they probably 
came from Station 271 (see Station 271).

Station 212 (Sounding 349), off Samboangan (see Chart 31). 
January 30, 1875 ; lat, 6° 45' N., long. 122° 18' E, 
Temperature of air at noon, 80°‘5 ; mean for the day, 80° ‘3. 
Temperature of water at surface, 83°‘0. 
Depth, 10 fathoms ; deposit. Sand, Gravel, and Mud, 
At 3 A.M. got up steam. At 4.30 a.m. weighed anchor and proceeded out of 
Samboangan Harbour under steam to S.E. to swing ship for deviation of compass, and 
errors of dipping-needle. Landed party of naturalists and officers to explore Malanipa 
Island. At 1 p.m. completed swinging ship. Proceeded towards Malanipa Island. 
Fired two guns and hoisted recall for exploring party. At 2.15 p.m. stopped about one 
mile N. of Malanipa Island and trawled and dredged in 10, 14, and 20 fathoms,
