ELECTRICAL TERMS AND DEFINITIONS. 



Interim Report of Committee on Electrical Terms and Definitions (Prof. Sir 

 J. B. Henderson, Chairman ; Prof. F. G. Baily and Prof. G. W. O. 

 Howe, Secretaries ; Prof. W. Cramp, Dr. W. D. Dye, Prof. W. H. 

 EccLES, Prof. C. L. Fortescue, Sir R. Glazebrook, Prof. A. E. 

 Kennelly, Prof. E. W. Marchant, Sir F. E. Smith, Dr. W. E. 

 SuMPNER, Prof. L. R. Wilberforce). 



The subject of electrical terms and definitions is being considered by many 

 committees in this and other countries. Different views are held in regard 

 to the meaning of some of the fundamental terms used in electromagnetic 

 science, and it is essential that international agreement should be obtained on 

 these important questions of terminology and definition. It is therefore very 

 desirable that this Committee should work in close co-operation with other 

 bodies considering the same subject. 



In December 193 1 a circular was issued by the Commission on Symbols, 

 Units and Nomenclature of the International Union of Physics. This 

 circular, which was in the form of a questionnaire dealing with the main 

 points on which diff"erences of opinion were known to exist, was sent to the 

 individual members of our Committee. 



In May 1932 the British National Committee of the International Union 

 of Physics convened a conference at the Royal Society to discuss proposals 

 drawn up by Sir Richard Glazebrook on the basis of the replies received to 

 the questionnaire. The members of our Committee were invited to attend 

 and take part in this conference. Although no unanimous decisions were 

 arrived at, votes were taken on the chief points of difference and by a 

 majority certain recommendations were approved . These were subsequently 

 discussed at an informal meeting in Paris, held in connection with the 

 Electrical Congress in July 1932, preparatory to the meeting of the Inter- 

 national Electrotechnical Commission which is to take place in Chicago in 

 1933- 



The Committee therefore ask to be reappointed.

 Beynon and Arthur H. Ogilvie : 



' Work was resumed on October 5, 193 1, and ceased on May 12, 1932. 



' Quarrying operations having opened a way into the North-East Gallery, 

 It was decided to take the opportunity of making some examination of this 

 chamber. The results, however, showed that no previous entrance had 

 existed there. Apart from remains of the usual Late Pleistocene fauna,
