 sented to the General Committee by Deputations from Liverpool, Edinbiu'gh, 

 Brighton, and Bradford. 



Report of the Keiv Committee of the British Association for the Ad- 

 vancement of Science for 1868-69. 



The Committee of the Kcw Observatory submit to the Council of the British 

 Association the following statement of their proceedings during the past 

 year : — 



The nature and amount of assistance to be rendered by this Committee to 

 the Meteorological Committee of the lloyal Society have now been clearly de- 

 fined, and the duties undertaken at Kew Observatory may, as in the last 

 Beport, for clearness" sake be again considered under the two following 

 heads : — 



(A) The work done under the direction of the British Association. 



(B) That done at Kew as the Central Observatory of the Meteorological 



Committee, 



This system of division will be adopted in this Eeport, and it has been 

 thought desirable, for the information of the Association, in the financial 

 statement hereto appended, to include the sums received from the Meteoro- 

 logical Committee as well as those received from the British Association. It 

 will thus be clearly seen that the woi'k done at Kew for the Meteorological 

 Committee has been paid for from funds suj^plied by that Committee, and not 

 in any way from money subscribed by the British Association.

1. Mac/netic ivorl: — The Self-recording Magnetographs ordered by the 

 Mauritius Government for Mr. Meldrum, after having been verified at Kew, 

 have been forwarded to their destination. 



A Unifilar and Dip-circle for Mr. Meldrum have likewise been verified. 



A Unifilar and Dip-circle have been repaired and verified for the Rev. M. 

 Colombel, who has gone to Nankin, where he intends making magnctical 

 observations. 



M. Colombel as well as M. Berg, of the Wilna Observatory, have received 

 magnetical instruction at Kew. 



A Dip-circle is in the course of being verified for Lieut. Elagin, of the 

 Bussian Navy. 



The usual monthly absolute determinations of the magnetic elements con- 

 tinue to be made by Mr. "Whipple, Magnetic Assistant. During the last year 

 it has been found necessary to replace the wooden pillars of the magnetic 

 house with pillars of Portland stone, which had been previously ascertained 

 to be non-magnetic. It has also been found necessary slightly to repair the 

 Unifilar and Dip-circle hitherto used in these monthly determinations. 



The Self-recording Magnetographs are in constant operation as heretofore, 

 also under the charge of Mr. Whipple, and the photographic department 

 connected with these instruments remains under the charge of Mr. Page. 



The task of tabulating and reducing the magnetic curves produced at Kew
