1 XO MARINE BAROMETER. 



Observations commonly to shift more to the southward in the day, and ta 

 and inferences blow more from east and NE in the night. The weather was 

 the^coirespon- '^'^^y hazy during these nine days; so much so, that for six 

 dent changes of them no observation of the sun's altitude, worthy of con- 

 wcrth'el-'tobe ^^^^^^^ ^^^^^ ^^ taken from the sea horizon, although the 

 expected after sun was sufficiently clear; and in the whole time, the mer- 

 change in the cyj-y never once stood so high as 30 inches, but was fre- 

 meter! ^^°~ Quently below 29,70. I considered this to be the more ex- 

 traordinary, as settled winds from the eastward, and especi- 

 ally from SE, had before made it rise and stand high upon 

 this coast, almost universally, even when tl^ere was a consi- 

 derable 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 mercury 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 mcr- 

 cuvy ascended to 30,14, and remained there as long as the 

 wind was southwardly. 



5ih. Going up the largest of the two inlets on the south 

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

 from SSW to SSE, sometimes with fine, sometimes with dull 

 weather, the mercury rising gradually from 30,08 to 30,22. 

 In twenty-four hours afterwards, it fell below 30 inches, and 

 a light breeze came from the northward, off the land, with 

 finer weather than before. The mercury continued to fall 

 to 29;56, where it stopped ; the wind having then ceased to 



blow
