terval, and height for parallax 57', which may be considered 

 as the semimenstrual inequality. 



In order to obtain the correction for declination from the 

 concurrence of as many observations as possible, I proceeded 

 nearly in the same manner as for parallax; the following 

 table is intended to give the correction in time and height 

 when the moon is in the equator, founded upon the totality 

 of the observations corresponding to a declination less than 

 15° north or south. 



* The figures in the columns marked with an asterisk cannot be liable 

 to any error of consequence, as they each may be considered as resulting 

 from about 800 observations. Those of the semimenstrual inequality are 

 each deduced from the mean of from 100 to 150 observations.
