be taken from the sea horizon, although the sun was suffi- 
ciently clear ; and in the whole time, the mercury never once 
stood so high as 30 inches, but was frequently below 29,70. 
I considered this to be the more extraordinary, as settled 
winds from the eastward, and especially from SE, had before 
made it rise and stand high upon this coast, almost univer- 
sally, even when there was a considerable degree of haze. 
The direction of the south coast, beyond the Isle of St. Francis, 
and even abreast of it, was at that time unknown to me ; but 
I then suspected, from this change in the barometer, that we 
should find the shore trending to the southward, which proved 
to be the case. The easterly winds, then, whilst they came 
off the sea, caused the mercury to rise upon the south coast ; 
but in this instance that they came from off the land, they 
produced a contrary effect ; but it is to be observed, that the 
most hazy part of the time, and that during which the mer- 
cury stood lowest, was two days that the wind kept almost 
constantly on the north side of west, more directly off the 
land: its height was then between 29,65 and 29,60. 
The haze did not immediately clear away on the wind 
shifting to the westward ; notwithstanding which, and that 
the new wind rose to a strong breeze, and was accompanied 
with squalls of rain, the mercury began to ascend, and had 
reached 29,95 when the squalls of wind and rain were 
strongest ; the direction of the wind being then from SSW. 
On its becoming moderate, between SSW and SSE, the mer- 
cury ascended to 30,14, and remained there as long as the 
wind was southwardly.

coast, in March, we were favoured with fine fresh breezes
