my place is 51 0 29' 5" N. and 41" of time weft of 
the obfervatory at Greenwich, between the phyfic- 
garden and Chelfea hofpital. 
Several obfervations * for verifying the quadrant, 
meridian, clock, &c. made at different times of the 
year, were as follow ; viz. 
22d December 1760. Altitude fun’s upper limb 
on the meridian 15 0 6 r 30". Error by calculation 
2 // of a degree. 
26th December 1760. Altitude fun’s upper limb 
on the meridian 15 0 12' 15". Error by calculation 
b" of a degree. 
2d January 1761. Altitude fun’s upper limb on 
the meridian 15 0 20' 42"* Error by calculation 3" 
of a degree. 
j 8th February 1761. Altitude fun’s upper limb 
on the meridian 27 0 22 ' 45 // . Error by calculation 
4" of a degree. 
6th February 1761. Sun on the meridian, by the 
clock, at 1 2 h 14' 35 // . Error by equation table o" 
of time. 
nth February 1761. morning, at io h 20, per 
clock. Altitude fun’s upper limb 20° 23'. Error 
of clock o" of time. 
nth February 1761, noon, fun on meridian, per 
clock, at 1 2 h 14' 44". Error by equation table o" 
of time. 
nth February 1761, afternoon, at 6 h 37' 3 o'* 
per clock. Altitude fun’s upper limb 6° 37' 3o // . 
Error of clock o" of time. 
* A great number of others were made, although not inferted
