Table t) A. Results of Declination Comparisons at the Dehra Dun Observatory, 1009. 



'All values are referred to station .S; .S = A'+0'.4. 

 T.\BLE 9B. Results of Horizontal-Intensity Comparisons at the Dehra Dun Observatory, 1909. 



'There is apparently no appreciable difference between S and N. 

 Table UC. Results of Inclination Comparisons at the Dehra Dun Observatory, 1909. 



'The station-difference appears to be negligible. 



Assembling the chief results and referring them to I. M. S. (see p. 273), we obtain: 



(9) I. M. S.- Dehra Dun (Elliott magnetometer No. I7)=0'.0 (1909). 

 (9a) I. M. S.- Dehra Dun (Elliott magnetometer No. 17)= +0.00144// (1909). 

 (%) I. M. S.- Dehra Dun (Earth inductor No. 30)= +0'.4 (1909).
