Report of the Kew Observatory Committee, 



385 



transcripts from the official publications ; in others they are deduced 

 from the recorded monthly or quarterly means. In a few instances 

 figures have been supplied by directors of observatories in answer to 

 special requests. 



With the consent of the Committee an analysis of the Declination 

 and Horizontal Force results for the selected " quiet days " of the 

 five years 1890 to 1894, extracted from previous Reports, with addi- 

 tional results required for a complete discussion, was drawn up by 

 the Superintendent, and appears as the Report of 4 the B. A. Com- 

 mittee for the Comparison and Reduction of Magnetic Observations,' 

 Ipswich, 1895. 



Professor Riicker and Mr. W. Watson spent some time at the Ob- 

 servatory in July and October, comparing their magnetic instruments 

 with the Kew Unifilar and Dip Circle, on behalf of the B. A. Com- 

 mittee for the Comparison of Magnetic Instruments (B.A. Report, 

 1895, p. 79). 



Captain Schiick visited the Observatory in June, and made a 

 series of observations in order to compare his own instruments with 

 those of Kew. 



The Magnetic Instruments have been studied, and a knowledge of 

 their manipulation obtained by Captain Field, Commander Cust, and 

 Lieutenant Dawson, of the Royal Navy. 



Information on matters relating to various magnetic data have 

 been supplied to Mr. Veeder, Captain Schiick, and Professor 

 Riicker. 



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's Monthly 

 Meteorological Magazine.'
