TO THE ARCTIC REGIONS. 17 
Busse, of Bridgewater, from which the island ob- 
tained the name of Buss. ‘This then, I believe, is 
the last account we have of this mysterious island, 
whose supposed ruins we have this afternoon been 
trying to find. 
Whilst sounding to-day, we availed ourselves of 
the opportunity thereby afforded, of ascertaining the 
temperature of the sea, at as great a depth as it had 
perhaps ever been obtained before. A self-regis- 
tering thermometer was tied to the sounding line at 
the distance of ten fathoms from the lead, or rather 
the clamm* ; for that was the instrument used on this 
occasion. Allowing, then, that there were one hun- 
dred fathoms of stray-line or inclination from the per- 
pendicular, which I think is the utmost that there 
could be, the thermometer must have gone upwards of 
one thousand fathoms below the surface. The temper- 
ature indicated by it at this depth was 452°, the tem- 
perature of the water at the surface at the same time 
being 484°, and the air 492°. 
Pacey, 28th. — We jaa to-day the jeeuiaiae 
of water brought: from the depth of one hundred 
and thirty fathoms by Dr. Marcett’s Water Bottle t 
to be 484°, both the air and sea at the surface 
being at the time 49°. | 
Monday, 31st. — We tried yesterday and to-day f 
. * This instrument is intended to bring up a greater quantity of 
sounding, (that is, of the mud, &c. at the bottom) than the usual 
arming of the lead was capable of bringing up. 
.. t The use of this machine is to bring water up from the bottom, 
or indeed from any other depth that a person may require; for 
the shot or weight that shuts the bottle is not let go until it is at 
the bottom, or at the depth that the water is to be brought from. 
} Our latitude yesterday at noon was 57° 46! N. and longitude 
29° 09' W., and to-day latitude 58° 13! N. and longitude 30° 20’. W.
