Oar the 22,1 of August, late in the evening, the
fell in temperature four degrees to 6+; f":
next day at noon having fallen to 62, and suspeet'''s
that «e might be in soundings, though no alter•
tion had taken place in the colour of the water,
induced the Captain to sound, but no bottom wa!,
found at 140 fathotn ; on the 24th it will appear 17
the.chart to have fallen to SS, and on the 25(1' !()
56, about which time we were undoubtedly on
(pet, or False Bank, and on the 26111 having faller',
to 51 at eight A. M. and assumed a green cast, A
was desirous of sounding again, but in consequene.le
of the ill success attending our former :attempt, and • •
not yet placing any reliance on the thermometer,
Ole Captain was unwilling to lose time in soundings
supposing that we were only approaching Jaquet of
False Bank ; but the next day having spoke a bank.
er, he informed us that we were on the Grand Banks
and that Cape Race bore W.N.W. 150 tntles.•
Upon sounding at noon we struck the ground at 3/
fathoms. -Here set me remark, that our reckoning •
as shewn on the chart has been well kept, and Oa!,
the thermometer has with great precision indicated°
our situation; on the zest at noon in a suppose

Our Captain, a sensible and observing ma'', ,d
well as very experienced mariner, struck with e
regular gradation of the thermometer on the 1/';
proach of the bank, and convinced of its 1`3•",;,'
pointed it out long before he had suspetled his

The journal from America to England, does h
more than confirm the previous observations m

in this track ; the thermometer fell no less than
degrees on passing to the southeast of New
land, and rose again 9 degrees in the same I°l,
tudes, where in our out voyage, we 5 'lt
posed ourselves to be crossing a branch of the or,
, Scream. The fall from hence of the' thermottle
as the coast of Europe is approached, is veil
markable and uniform.
