TRANSIT OF VENUS, 1874. NEW ZEALAND. BURNHAM. 



nated at night with those of the close circumpolar stars observed for azimuth 

 error : 



Mark East

Mark East

1874, December 



1876, January 



The adopted position of the meridian mark is 4"'65 East of South. 



The observations of the mark are entered in Table III. ; each micrometer 

 reading there given represents the mean of five or more bisections of the 

 mark, generally when illuminated at night. 



TRANSITS OF STARS AND OF THE MOON OBSERVED AT BURNHAM. 

 (Abstract of Tables IV. atul V.} 



The transits of stars observed on all days when the Moon was also observed, 

 either with the Transit instrument or with the Altazimuth, are given in the 

 same detail as for other stations. The observations were completely reduced 

 by Major Palmer. 



The transit-micrometer was kept at 20 r- 000 for all clock stars, and the 

 bisections of circumpolar stars with the center wire were so taken that the 

 mean micrometer-reading was 20 r> 000. 



For the Moon, the transit was corrected in the same manner as a transit of 

 a star. A correction was then applied for the Moon's motion, which was 

 obtained by multiplying the sum of the instrumental corrections by the 

 Moon's motion in R.A. in one second of longitude.
