No. 18, A.! for llr. 989 read 10.989 



The whole series of printed A i is evidently computed by the employment of the differences 



corresponding to the third and second threads, instead of the second and first ; and it has 



been taken for granted that the observation was made in this way. Otherwise the A<J must 



be increased by 3". and 3". 11 respectively. 

 No. 3, AJ for 21r. 736 read 21r. 734 

 " 15 " llr. HO " llr. 144 



The sign of A<5 should be negative. 

 No. 16, Ad for 26r. 171 read 26r. 231 



Micr. perhaps 46r. 391, which has been adopted. 

 No. 6-9, Some error in the time must exist here, probably in the minutes ; as also between 



Nos. 33 and 41. 



No. 76, Micr. for 2 59. 631 read 2 57. 631 

 The comparison-star is not in Taylor.
