eter is one of the oldest of the Kew pattern manufactured by Jones and observation 

 with it is somewhat difficult. The Observatory values for horizontal intensity depend 

 upon a mean value of the distribution coefficient obtained from observations covering 

 a period of 14 years. The C.I.W. instrument used was magnetometer-inductor No. 26. 

 The corrections on International Magnetic Standards," applied to results obtained with 

 magnetometer-inductor No. 26, were those finally adopted.

The times given apply for the C. I. W. observations; the Stonyhurst College observations were not strictly simultan- 

 eous but the intervals between the mean times for corresponding seta are not large enough to affect materially the values for 

 (I. M. S. Stonyhurst), as indicated by the magnetograms. 



All values are referred to station A; A = B-\-15y.
