From these two Tables, which are formed from the Transit Table, the 
following rates for the clock, contained in Tables III. and IV. have been 
computed. 
Those in Table III. by dividing the difference between the times of 
transit of each star, on the successive days as given in Table I. by the 
interval in days, substracting the quotient from 3 m 55 s -9i, the accelera- 
tion in one day, and applying a correction to the remainder, for the change 
in ill of each star during the interval of their respective successive transits, 
to obtain the rate in a sidereal day. 
Those in Table IV. by comparing the time by the clock at the moment 
of mean noon of each day, as shown in Table II. with that on each suc- 
ceeding day, and dividing the difference by the number of days in the 
interval, by which the rate in a mean solar day for 21 separate intervals 
has been obtained.
