who are now engaged in collecting climatic and ecological data of the 
different countries of the British Empire. Corresponding maps are being 
prepared, and it is hoped that a fairly complete series will be ready by the 
end of the year. The Committee has held one meeting, in conjunction with 
its collaborators, at which progress was reviewed and a programme outlined 
for the continuation of the work.

Prof. G. Coox, Prof. B. P. Haicu, Mr. J. S. Witsown). 
Tue following interim report is submitted : 
“The work of the Committee on the yield point and on stress distributions 
in the initial stages of plastic yield in a variety of cases is proceeding. It is 
hoped that a full report of these experiments will be submitted in 1934.’ 
The Committee ask to be reappointed for another year. 
ELECTRICAL TERMS AND DEFINITIONS. 
Report of Committee on Electrical Terms and Definitions (Prof. Sir J. B.

K.C.B., C.B.E., Sec. R.S., Prof. L. R. WILBERFORCE). 
IN last year’s report reference was made to the undesirability of making 
a technical report pending the decision of the Symbols, Units and 
Nomenclature (S.U.N.) Commission of the International Union of Physics 
which had just been constituted. 
This Commission has reported, and this report goes a long way to 
remove the difficulties our Committee had encountered. As further reports 
of the above Symbols, Units and Nomenclature Commission are expected, 
we ask for reappointment. 
The Committee’ ask for reappointment without grant.
