No. 18, A&amp;lt;5 for llr. 989 read 10.989 



The whole series of printed A &amp;lt;5 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(5 must 



be increased by 3&quot;. and 3&quot;. 11 respectively. 

 No. 3, AJ for 2lr. 736 read 21r. 734 

 &quot; 15 &quot; llr. 140 &quot; llr. 144 



The sign of At should be negative. 

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



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

 No. 5-9, Some error in the tune 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.
