 Lord Kelvin, Professor Ayrton, Professor J. Perry, Professor 

 W. Gr. Adams, Lord Kayleigh, Dr. 0. J. Lodge, Dr. John

 J. V. Jones, Dr. Gr. Johnstone Stoney, and Professor S. P. 

 Thompson, appointed for the purpose of constructing and issu- 

 ing Practical Standards for use in Electrical Measurements. 



The work of testing resistance coils at the Cavendisli Laboratory has 

 been continued. A table of values found for the coils is appended. The 

 Committee have ceased issuing standards in terms of the legal ohm of 

 the Paris Congress. As will be seen from Table I., most of the coils 

 tested are ohms as defined by the resolutions of the Committee and the 

 Electrical Standards Committee of the Board of Trade (see ' B.A. Reports,' 

 1890 and 1891). According to these 



1 B.A. unit= -9866 ohm. 

 1 ohm =1-01358 B.A.U.
