Report of the Kew Committee. 



to the Meteorological Committee, but modified by Mr. Beckley, on the 

 suggestion of Mr. De La Rue, so as to express the velocity by hourly 

 traces, the pencil returning at the expiration of each hour to the zero- 

 line, and also to admit of a range to the extent of 100 miles in the hour, 

 has been tested and found to work satisfactorily. 



Various other Anemometers of different constructions have been under 

 experiment ; but from the limitation of the space forming the Observatory 

 garden, by trees, &c, it was not practicable to test thoroughly their re- 

 spective merits. ' 



"Waxed paper for photographic purposes has been supplied to the India 

 Office (2J reams), the Meteorological Office (5 reams), and the Lisbon 

 Observatory (| ream). 



Instruction in the use of Magnetical or Meteorological Instruments has 

 been given to the following gentlemen : — 



Prof. H. F. Blanford, Meteorological Reporter to the Government of 

 Bengal, in Meteorological work. 



The Bight Rev. the Bishop of Rupert's Land, in Meteorological work. 



Charles Carpmael, Esq., B.A., Assistant to Mr. Kingston, Magnetic 

 Observatory, Toronto, Canada, in both Magnetical and Meteorological 

 work. 



Three Officers of the North-iVmerican Boundary Commission, in Mag- 

 netical work. 



Three Officers of H.M.S. ' Challenger,' in Magnetical work. 



Instruments and Apparatus. — The several pieces of Apparatus &c. 

 enumerated in the Inventory (Appendix II. of the Report of the British 

 Association, 1871) have been handed over to the Kew Committee, and 

 are in their charge. 



In the month of July instructions were received from the Foreign 

 Office to deliver to Capt. Anderson, R.E., an officer attached to the 

 North-American Boundary Commission, the Magnetic Instruments used 

 by the previous Commission, which had been deposited at Kew by the 

 late Major R. W. Haig, R.A. Accordingly the following instruments 

 were given up to Capt. Anderson : — A portable Unifilar, a Dip-circle, 

 and an Azimuth Compass. 



The last-named instrument, although deposited by Major Haig, was 

 not mentioned in the letter from the Foreign Office, and it was therefore 

 issued to Capt. Anderson on loan. 



The Dip-circle mentioned in the last Kew Report of the British 

 Association has been lent to His Excellency Major-General Lefroy, 

 Governor of Bermuda. 



A portable Dip-instrument, which had been lent to the Astronomer 

 Royal for a brief period, has been returned by him. 



Buildings. — Some slight alterations have been made in the main 

 buildings in order to afford additional accommodation. 



A small closet in the Testing-room has been converted into a Lavatory.
