TRANSIT OF VENUS, 1874. KAILUA. 



The mean of these is +0 S< 28 ; December 3 and 31 are correctly reduced. 

 On the few occasions when stars were observed with the instrument in one 

 position only, one half of this quantity has been applied to the mean clock 

 slow in Table V. The chronometric connection with Honolulu is, however, 

 unaffected by them. The clock correction applied to the transit of the Moon 

 is, of course, that proper to the position of the instrument. 



MERIDIONAL TRANSITS of the MOON observed at KAILUA, and 

 inferred LONGITUDE. 



In Table IV. are given the clock time, properly corrected, of the passage 

 of the Moon's limb over the true Meridian (affected, however, by diurnal 

 aberration) and the clock correction at that instant. The following results 

 have been obtained by interpolation, with fourth differences, from the section 

 Moon Culminating Stars in the Nautical Almanac. The corrections to the 

 Ephemeris are taken from the Appendix. 



* On December 1 5 and 22 stars were not observed at the same time as the Moon. 



Professor Forbes' station was also connected with the head station at 

 Honolulu by transportation of chronometers. This work has been given in 

 sufficient detail in the preceding account of operations at Honolulu. f The 

 difference of longitude between the transit piers of the two stations was found 

 to be 7 m . 24 S< 64. The adopted longitude of the Transit Pier at Honolulu is
