Report of the Kew Observatory Committee. 163 



Observations of Absolute Declination, Horizontal Intensity, and 

 Inclination have been made weekly, as a rule. 



As in 1896, a table of recent values of the Magnetic Elements at 

 the Observatories whose publications are received at Kew was con- 

 tributed to ' Science Progress,' and appeared in the August number. 

 A similar table, but containing more recent data, will be found in 

 Appendix IA to the present Report. 



In July, M. Moureaux, of the Pare Saint-Maur Observatory, near 

 Paris, paid a visit, and a comparison was made of his and the Kew 

 magnetic instruments, a detailed report of which has been drawn up 

 by the Superintendent, and published in the Royal Society's Pro- 

 ceedings, vol. 62, p. 156. 



The magnetic instruments lent to the Jackson-Harmsworth Polar 

 Expedition have been returned, and in October some observations 

 were taken with them by Mr. Albert Armitage, the Magnetic 

 Observer in the expedition, and the Observatory Staff, with a view 

 to standardizing the Arctic Observations. 



Dr. van Rijckevorsel spent some time at the Observatory, in 

 March and April, comparing his magnetic instruments with the Kew 

 unifilar and dip circle. 



Information on matters relating to various magnetic data have 

 been supplied to Dr. E. Atkinson, Professor Arnold Lupton, and 

 Captain Schiick, and the latter gentleman compared his instruments 

 with the Observatory standards. 



II. METEOROLOGICAL OBSERVATIONS. 



The several self-recording instruments for the continuous registra- 

 tion of Atmospheric Pressure, Temperature of Air and Wet-bulb, 

 Wind (direction and velocity), Bright Sunshine, and Rain, have been 

 maintained in regular operation throughout the year, and the 

 standard eye observations for the control of the automatic records 

 duly registered. 



The tabulations of the meteorological traces have been regularly 

 made, and these, as well as copies of the eye observations, with . 

 notes of weather, cloud, and sunshine, have been transmitted, as usual, 

 to the Meteorological Office. 



With the sanction of the Meteorological Council, data have been 

 supplied to the Council of the Royal Meteorological Society, the 

 Institute of Mining Engineers, and the editor of ' Symons' Monthly 

 Meteorological Magazine.' 



On June 21, observations with the Campbell sunshine recorder, of 

 the original wooden bowl pattern, were suspended, by direction of the 

 Meteorological Council.
