Eeport of the Keiv Committee for the Year ending 

 Octoher 31, 1876. 



Magnetic WorTc. — The Magnetographs have been in constant operation, 

 throughout the year. The horizontal-force instrument has undergone 

 readjustment of its suspension on two occasions, in order to increase its 

 sensibility, which appears to have somewhat diminished of late. 



In accordance wdth the nsnal practice, determinations of the scale- 

 values of all the instruments were made in the first week of the new 

 year, and of the Bifilar when required. 



The monthly observations with the absolute instruments have been, 

 continued, as usual, by Mr. Whipple and Mr. Eigg, and the results are 

 given in the Tables appended to this Eeport. 



The paper referred to in the last Eeport, containing the results of the 

 Absolute Observations for the six years ending March 1875, having been 

 read before the Eoyal Society, has been printed in vol. xxiv. of the ' Pro- 

 ceedings.' 



The two Sergeants of the Eoyal Artillery, formerly in Sir E. Sabine's 

 office at Woolwich, have been in regular attendance at Kew throughout 

 the year, principally engaged in the preparation of his paper " Contri- 

 butions to Terrestrial Magnetism, No. XY.," which will be printed in 

 the Philosophical Transactions.
