TRANSIT OF VENUS, 1874. KODEIGUEZ. POINT VENUS. 



COMPARISON of the OBSERVED and TABULAR ZENITH DISTANCES of STARS OBSERVED 

 in VERTICAL TRANSIT with the ALTAZIMUTH at POINT VENUS. 



* October 16, S Sagittarii. Lamp Left gives 25"' 8 ; December 5, 8 Orionis, Lamp Bight, gives + 22"' 3. 



[The mass of calculations connected with the Altazimuth observations is so 

 great, and the complete examination of any one by any future investigator 

 so improbable, that I determined to withdraw from publication all except the 

 results. The calculations had been most severely checked by Major Tupman, 

 and the manuscripts are preserved at the Eoyal Observatory. Gr. B. A.] 



The following are the results for the longitude deduced from the observed 

 Zenith Distances of the Moon, corrected for the constant error of O04 in the 

 Sidereal time as described on page 355.
