From whence the latitude of the point of land called the North Cape 
is 71° 10' north. 
By a great many trials with a very good compafs, of Dr. Knight’s conftruftion, I found the 
variation to be 6 degrees welt ; and by a dipping needle, I found, by repeated trials, the dip 
of the north end of the needle to be 79 degrees. 
' May 15, at 13'' P. M. apparent time, or after high water, by a mean of 7 obfer- 
vations, I found the dip of the horizon of the Tea, from the obfervatory, to be 12' 1 8". 
Height of the barometer 29,70 inches ; thermometer, without, 24° ; thermometer, within, 
28°. And May 20, at 7*“ 5 P. M. apparent time, or 7** 33' after high water, from a mean of 
8 obfervations, 1 found the dip — 12' barometer 29,70 inches; thermometer, with- 
out, 43°, and, within, 40°. Both thefe obfervations were made on the N. N. E. point of the 
truecompafs. During each of thefe obfervations the water was very fmooth, and the horizon 
clear. 1 found it was high water, at the full and change of the Moon, at 3*' 44' P. M. ap- 
parent time, at the Cape ; and, by a feries of obfervations, I found the water to rife 8 feet 
I inch, nearly, perpendicular at the fpring tides ; and at neap tides 6 feet 8 inches, perpendi- 
cular ; and the tides feemed to follow very regular, as they ought to do when not dillurbed 
by bad weather June 8, I found the height of the obfervatory 140 feet 6 inches above 
low W’ater mark.
