Mr. Flinders's Observations 
when the wind was at SSW with similar weather ; the reason 
of which may probably be, that at some distance to the south- 
ward these westwardly winds blew more from the south, and 
were turned out of their course, either by the mountains, or 
by meeting with a north-west wind farther to the northward. 
The winds from north and NW blew very seldom at this 
time : the mercury fell on their approach. 
To the state of the mercury during our second stay at Port 
Jackson, in July, 1803, and part of June and August, it is not 
in my power to refer, as I have not been able to obtain that 
part of my journal from General De CaSn. 
The effects of some winds upon the barometer in this 2d 
example, are considerably different to what they were upon 
the south coast. The wind at WSW or SW with fine weather, 
had always caused the mercury to rise and stand high, and 
those from the NE to fall ; whereas here, the effects of those 
winds were almost directly the reverse. The winds from 
SSW, SE, and as far as east, made it rise on both coasts, with 
the exception of the 4th example on the south ; and from 
between north and WNW the mercury fell in both cases and 
stood low. 
3d. Steering along the east coast, from Port Jackson to 
the northward, in July, we had the winds usually between 
south and SW, and sometimes WSW, the mercury being 
nearly stationary at 30 inches ; but meeting with a spurt of 
the south-east trade wind in latitude 24 0 , we found it rise to 
30,30 for two days. A westwardly wind brought it back to 
30 inches for a short time ; but on the trade wind finally 
setting in, it fixed itself between 30,20 and 30,30, as long as 
the wind preserved its true direction.
