Report of the Kew Committee for the Year ending

October 31, 1878.

The Kew Committee has had its strength increased during the past year by the accession of two new members, Professor W. G. Adams and Professor G. C. Foster, and is now constituted as follows:

General Sir E. Sabine, K.C.B., Chairman. Mr. De La Rue, Vice-Chairman. The Earl of Rosse. Prof. W. G. Adams.

Mr. R. H. Scott. Capt. Evans, C.B.

Lieut.-General W. J. Smythe. Prof. G. C. Foster.

Lieut.-General R. Strachey, Mr. F. Galton.

C.S.I.
Vice-Adm. Sir G. H. Richards, Mr. E. Walker.

K.C.B. Magnetic Work. The Magnetographs have been in constant operation throughout the year, but only few magnetic disturbances have been registered, the period being one of almost continued magnetic calm. The most notable perturbation was that of May 15th.

The scale values of all the instruments were re-determined in January, in accordance with the usual practice.

A slight alteration has been made in the cases enclosing the hori. zontal and vertical force magnets; zinc cylinders with glass covers being substituted for the glass shades lined with gold-leaf previously employed, which were found to be very expensive to replace in case of breakage.

The tabulation of the magnetic curves has not been continued during the year, the time of the department being very fully occupied with the verification of magnetic instruments.

The Committee have referred the whole subject of the reduction of the accumulated magnetograph records to a Sub-Committee, with a view of considering what steps shall be taken to utilize them to the best advantage.

The monthly observations with the absolute instruments have been

made as usual by Mr. Figg, and the results are given in Tables appended to this Report.

The catalogue of the documents and papers in the late Magnetic Office, directed by Sir E. Sabine, having been completed, a selection was made of all those relating to marine observations, and at the request of the Hyılrographer, these were transferred to the Hydrographic Department of the Admiralty.

The magnetic instruments have been examined and knowledge of their manipulation obtained by Lieutenants Speelman and van Hasselt, of the Dutch Navy; Professor Greene, of the United States Navy; M. Hooreman, of the Brussels Observatory; and Dr. T. E. Thorpe, F.R.S.

The latter gentleman made a series of base observations at Kew before and after an extended tour, for the purpose of a magnetic survey along the fortieth parallel of latitude in the United States.

A large magnet and a journeyman clock, the property of the Royal Observatory, Greenwich, which have been for many years at Kew, have been returned to the former establishment at the request of the Astronomer Royal.

Information on matters relating to terrestrial magnetism and various data have been supplied to the Hydrographic Office, Mr. Adie, Mr. Archbutt, Mr. Gordon, and Mr. Frost.

Meteorological Work.—The several self-recording instruments for the continuous registration respectively of pressure, temperature, humidity, wind (direction and velocity), and rain have been maintained in regular operation under the care of Mr. T. W. Baker, assisted by J. Hillier.

The daily standard eye observations, for the control of the automatic records have been made regularly, as well as daily observations in connexion with the Washington synchronous system.

The tabulation of the meteorological traces has been regularly carried on by Mr. Hawkesworth, and copies have been transmitted weekly to the Meteorological Office.

In compliance with a request made by the Meteorological Council to the Kew Committee, the Observatories at Aberdeen, Armagh. Falmouth, Glasgow, Stonyhurst, and Valencia have been visited and their instruments inspected by Mr. Whipple, who has also inspected the telegraph-reporting and climatological stations throughout Ireland, an allowance has been made by the Meteorological Office to Kew, for the time occupied by Mr. Whipple on this duty.

With the sanction of the Meteorological Council, weekly abstracts of the meteorological results have been regularly forwarded to and published by “the Times,” “Illustrated London News,” and “Mid. Surrey Times ;” and meteorological data have been supplied amongst others to Mr. G. J. Symons, F.R.S., Dr. Rowland, Mr. Mawley, and the Institute of Mining Engineers.
