TRANSIT OF VENUS, 1874. HONOLULU. 



In these formulae 8 and h are the geocentric declination and hour angle 

 respectively ; 8 1 and h l the apparent values ; p is the Moon's equatorial 

 horizontal parallax corrected for the latitude of the place ; 4> the geocentric 

 latitude. 



For the Augmentation of the Moon's semidiameter the approximate apparent 

 altitude was computed, and the Augmentation taken from the table in LOOMIS' 

 Astronomy, 7th edition, page 378. A constant correction of 2"'00 was 

 applied to the augmented semidiameter, all the occultations having been 

 disappearances at the Moon's dark limb.
