A VOYAGE TO 
[So- 'I Coast. 
3802. that or the neighbouring lands. Whilst beating through the Back- 
SatuKiayio. stairs Passage, I had observed an amplitude when the ship's head 
was south-south-west, which gave the extraordinary variation of 
2° 41' east, or reduced to the meridian, 1" 27' east; although we 
were then not so much as four miles from the anchorage where it 
had been found 4 0 13' east. Another amplitude was observed at 
eight leagues to the east of Cape Willoughby, when the head was 
north-east-half-east, and gave 2 0 5' east variation, or reduced, 4 0 36' 
This last is correspondent with what was observed near Kanguroo 
Head and in the Gulph of St. Vincent ; but the variation of i° 27' 
in the passage is totally irregular, and must I think be ascribed 
to an attraction either in Cape Jervis to the north-east, or in the east 
end of Kanguroo Island to the south-east, or to both. When the 
great variation of 4 0 36' was obtained, both these lands were to the 
west ; and when afterwards the i° 57' and i° 30' were observed, the 
nearest land was again to the eastward of the ship ; and nearest in 
the last case, t 
The winds continued to be light and unfavourable ; but by 
taking advantage of the changes in direction, and keeping further 
from the land, out of the tide or current, we had gained eight leagues

At one o'clock we bore away along the coast, with a light

Monday 12. tacked to seaward soon after dark. Next morning, we again fol- 
lowed the coast at the distance of from five to three miles ; and at
