eastward of south, a second rise took place, and for forty 
hours the mercury stood as high as 3045, the wind being 
then between SE by S and east : the weather was very dull 
and hazy during the first half of these forty hours, but finer 
afterwards. As the winds between SE by S and east slanted 
off the main land, this example seems to be in opposition to 
the 4th, and leads me to think, that it might have been the 
very extraordinary kind of haze, and perhaps some peculiarity 
in the interior part of the land abreast of the Isle of St. 
Francis that in part occasioned the fall of the mercury with 
south-east winds ; as much, perhaps, as the circumstance of 
the wind coming from off the shore. 
After this rise in the mercury to 30,45, it fell gradually ; 
but, for thirteen days, kept above 30 inches, the winds being 
generally between SE and SW, but light and variable, and 
the weather mostly fine. 
7 th. North-eastwardly winds, off the land, were the next 
that prevailed ; they were light, and accompanied with cloudy 
weather and spitting rain. The mercury fell to 29,70, and 
remained there till the wind shifted to the west and south- 
ward, when it began to rise, and in two days was up to 30,42. 
At that time we were off the projection marked n in the 
chart, in 139I- 0 east longitude ; the wind had then veered to 
the south-eastward along the shore, with a steady breeze, 
and the mercury remained nearly stationary so long as it 
lasted ; but on the wind dying off, and flawing from one side 
and the other, it descended quickly to 30 inches. A breeze 
then sprung up at NW, which, within twenty-four hours, 
shifted suddenly to SW, and blew a gale which had near 
proved fatal to us. It was accompanied with rain and very
