Longitude of Veracruz west from Paris, 



The preceding Table contains observations of distances of the 

 moon from the sun and stars in Vera Cruz and Porto-Rico, 

 and the number of observations being equal on the east and 

 west of the moon, the errors of them must be very nearly des- 

 troyed. 



The longitudes are deduced by a comparison with the nau- 

 tical almanac; and to the mean of the results 1 have added the 

 corrections which are found in the tables, arising from the fol- 

 lowing considerations. 



The tables of Mason which have been used for the calcula- 

 tions of the moon in the nautical almanac, suppose the epoch 

 of the mean longitude of the moon in 1750 6* 08° 22' 21"
