\prll * 3 , 29, and 30, got the obfcrvatory and dwelling houfe built, and indru- 
ments on Ihore. 
Set up an oak plank 4I inches thick, and 14. inches wide. This plank was feta 
little more than 2 feet in the ground, and well rammed with earth and ftones fo 
that it was very Heady and firm ; to which I fcresveJ the artronomical clock truly 
perpendicular (by which means it was independant of the obfervatory and its 
fhaking by the wind) and let it going nearly with fidereal time. 
Set up the tranfit inftrument nearly in the meridian. 
Examined the line of collimation of the quadrant, and found it correfl. 
Examined the clock, and found the pendulum to vibrate i°t on each fide of nothing. 
« 
Mere follow fome correfponding altitudes of the Sun, fiom which the going of the 
clock is determined.
