Table 3C. Results of Inclination Comparisons at the Christchurch Observatory, 1915, 1916, and 1920. 



' Values for 1915 and 1916 are referred to west pier, using the station-differences determined in November 1915, viz, 

 west pier= jarrah peg + 0'.23= brass pipe+Q'.23; for the work of February 27 and April 11, 1916, it is assumed that any 

 station-difference between east pier and west pier is negligible; values for 1920 are referred to west pier, using station-difference 

 then determined, viz, west pier jarrah peg+0'.01. 



The Christchurch values are from the magnetograms which apply for west pier.
