XCIX 
The following Table contains the Longitude by each of the Chronometers 
selected for final determination in 1820; that of No. 259 being the same as 
is deduced from the Observations in the preceding Abstract. 
The authority, on which the Daily Corrections to Mean Greenwich Time 
for Rate and original Difference are founded, is explained in Appendix, pages 
X. and xi. 
The last column contains the corrected or received Longitude, being the 
Mean Result of the four Chronometers.
