by the two Sorts of Quadrants, was commonly no 
-more than 1' ; with ftrong Gales and a large Sea 5 ' j 
in fair Weather ; in hard Squalls ; the Sea running 
high, 6‘ 3 in eafy Gales 9' ; in fair Weather and a 
large Swell 1 6' ; once in fmooth Water 16' ; and the 
greateft Difference of all was, with frefh Gales, 21' r 
And this Difference was conftantly found to give the 
Latitude more Northerly by Mr. Elton's Quadrant 
than by Davis's ; as in this laft mentioned Inftance 
the Latitude appears to be 35° 39' N. by Davis' s, 
when Mr. Elton's makes it 36° N. There is a Note 
added by Capt. Hoxton at the End of this Journal ; 
viz. That the Difference at different Times be- 
tween Davis’r and Elton’r Quadrants is occaftoned 
by pifting the Shade-Fane of DavisV. 
To this Journal were annexed fome u Obfervations 
M of the Latitude by the fixed Stars in the forefaid 
“ Voyage by Mr. Elton's Quadrant, without uiing 
“ the Horizon.” 
Thefe Obfervations are generally taken from two 
Stars, and the Latitude calculated from each Obfer- 
vation ; and fo they are found to agree commonly 
within 4' or 5'. The greateft Difference arofe once 
to 13'. When by an Obfervation taken by * Syrius, 
the Latitude was found to be 
42° 46' N.
