B. OBSEEVATIONS OF MAES II. WITH THE SANTIAGO MEEIDIAN-CIECLE. 

 The only remarks needed, relative to this series, are these : 



Page 309, note k, for 1 21 . 30 read 1 21&quot;. 27. 



311, the observation N. 7 has not been used. 



312, Jan. 28. For 24 28 56&quot;.97 read 24 28 53&quot;.97. 



312, Feb. 1. The sign of Nadir-reading should be positive. 



313, note I. The star is measured from Bessel 341. 

 314, /and g. Keference-letters should be transposed. 

 318, Mar. 23. Far 24 33 35&quot;.04 read 22 33 35&quot;.04. 



The observations in this series are of two classes : the first, consisting of microscope-readings 

 after setting the fixed thread upon the limb of the planet ; the second, of micrometric differences 

 from some near star. The latter cases are indicated in the foot-notes. This second class of 

 observations has been treated like the micrometric measurements ; with the equatorial and the 

 measured differences applied to the star-place, not as it was observed on that day, but as de 

 rived from our General Catalogue. This being kept in view, we deduce the appended table, in 

 which the semi-diameter is not applied ; inasmuch as this is derived from computation., and 

 incorporated in the computed place of the observed limb.
