Report of the Kew Committee for the year ending October 31, 1875

Magnetic Work.—The year has been marked by the recommencement of regular work with the Magnetographs, which had been taken down for examination and repair by Mr. Adie, as described in the last Report. The scale-values having been redetermined, the instruments were set in action on the 1st of January, 1875, and therewith the second series of continuous photographic records of magnetic phenomena was inau­gurated. The monthly observations with the absolute instruments have been continued, as usual, by Mr. G. M. Whipple, who also takes charge of the general magnetic work, in which he has had the assistance of Mr. Cullum and F. Figg. The two Sergeants of the Royal Artillery, formerly in. Sir E. Sabine's office at Woolwich, have been in regular attendance at Kew throughout the year.
