APPENDIX. 



Aiiguft the fourteenth, we landed the Pendulum, 

 Equatorial Inftrument, and aftronomlcal Quadrant on 

 Smeerenberg Point, latitude 79° 44' N; and fet up 

 the pendulum in every refpeft as formerly defcribed. 

 The equatorial and quadrant were alfo fet up, and pre- 

 pared for obfervation. 



The pendulum was fet a going when it was exadlly 

 6^ o^ d' P. M. by my watch, from which time it was fre- 

 quently compared with the watch, till 5^ 50' A. M. the 

 15th; when the pendulum flopped. It was again fet 

 a going with the additional weight which had formerly 

 been uled, when the watch was exadly 6^ 00' 00''', and 

 continued going from that time till after five in the 

 morning of the i8th, in which time the thermometer was 

 obferved. and the watch and pendulum compared, as in the 

 following table : many altitudes of the fun were taken 

 with the quadrant, on the 15th A. M. but without any 

 further opportunity till the i8th A. M. when they were 

 repeated to afcertain the rate of the watch's lofi.ng.
