Two additional series of temperature soundings were taken 
at this station—one at intervals of 10 fathoms down to 100, 
and a second at the odd fifties down to 450. These soundings 
completed and entirely corroborated the first series.

Slip water-bottles were used to bring up samples of water 
from different depths for the determination of the specific 
gravity and for analysis. 
On the 1st of April the mud brought up from 2600 fathoms 
was the same as that dredged the day before, and it seemed to 
give so little promise of a successful haul that we did not re- 
peat the operation. The second gig was sent out to bring in 
some of the patches of gulf-weed which were passing the ship 
in large numbers, and to collect surface animals. 
On the 2d of April, at a distance of 134 miles from Bermu- 
das, a series of temperature soundings were taken at intervals of 
20 fathoms from the surface to 800 fathoms, with the following

It will be seen by reference to Plate IX. that not only does 
the layer of superheated water maintain its position, but its
