Mr. Renneli/s Observations on a Current 
of Cape Clear,* in the parallel of 5 T; where its effects were 
no longer perceptible. And, as no current was felt in the track 
southward, on the 1 ith ; nor in any part of the track to the 
north-west, between tire 3d and 10th ; although it was felt' 
nearly in the same line of direction, between the 1st and 3d; 
it may be inferred that the stream goes off to the north- 
west, between the aforesaid track, and the south-west coast of 
Ireland. It is much to be regretted that no observations ap- 
pear on the 12th and 13th ; which would have been decisive 
of its course. 
I come now to two particulars of the case, which, I con- 
fess, perplex me exceedingly. The first is, that the current 
was felt, apparently in its full strength, on the fourth day af- 
ter the commencement of the gale ; which began at south, 
then changed suddenly to the west and WSW, and after- 
wards fixed in the SW quarter. This gale was felt between 
the 48th and 50th degrees of latitude, and, no doubt, ex- 
tended its effects very far to the south and west ; but what 
the state of the winds had been in those quarters, previous to 
the 27th of January, we are ignorant. The winds in the Bri- 
tish Channel had been easterly, for three days preceding the 
gale : the fourth day, preceding, there had been strong gales 
at SW ; and the five days preceding that , there had been 
chiefly light winds at west. According to this state of facts, 
we can only suppose that the current originated from a vast 
body of water, pent up in the Bay of Biscay, by violent gales 
of wind ; first from the southward, eleven hours ; then from 
a point or two to the south cf west ; and lastly, at south-west, 
* Cape Clear is reckoned to be in long. 9 0 25' from London.
