The small dredge was put over early on the following morning 
with a bread-bag lining to the net, and a 28-lb. weight slung to 
the tangle-bar. In the forenoon a sounding was taken in 2675 
fathoms with a hydra machine weighted with 3 cwt., having a 
water-bottle and two thermometers attached. It seems that the 
weights did not detach, for there was a great strain in heaving 
in, and finally the line parted, and the observations on tempera- 
ture and on the specific gravity of the water were lost. The 
dredge came up with a small quantity of mud containing many 
shells of foraminifera; the finest part of the mud having been, 
as is usual at these great depths, almost entirely washed through 
the bread-bag. The dredge contained no animals higher in the 
scale than foraminifera which we could say with any certainty 
had come from the bottom. 
On the 29th it was blowing hard with a heavy swell, and our 
first attempt to take a series of temperatures was unsuccessful. 
In the morning the starboard wheel-rope was carried away, and 
the necessary repairs caused some delay. Later in the day the 
swell moderated somewhat, and we took a temperature sounding 
down to 650 fathoms at intervals of 50 fathoms (Appendix A), 
and of 25 fathoms to 250:

There was as yet no rise in the surface temperature sufficiently 
marked to indicate that we were in any way affected by the 
stream. 
On the 20th of April, at 8 at, the temperature of the sea-
