xlvi. ABSTRACT OF PROCEEDINGS. 
Old, Richard; North Sydney. 
Kennedy, Thomas, Assoc. M. Inst. C.5., L.S.; Public Works 
Department. 
Stoddart, Rev. A. G.; Manly. 
The certificates of two candidates were read for the 
third time, and of three for the second time. 
Twenty-nine volumes, 177 parts, 30 reports, 7 pamphlets, 
and one geological map, total 244, received as donations 
since the last meeting were laid upon the table and 
acknowledged. 
The President announced that the Council had unanim- 
ously awarded the Clarke Memorial Medal to Mr. A. W. 
Howilrt, F.G.s., of Melbourne. 
THE FOLLOWING PAPERS WERE READ: 
1. “A comparison of the Periods of the Electrical Vibra- 
tions associated with Simple Circuits,’ by J. A. 
PoLLocK, Professor of Physics in the University of 
Sydney, with an appendix by J.C. CLOSE, Deas-Thomson 
Scholar in Physics. 
In the research the periods of the electrical vibrations 
connected with narrow rectangular closed circuits have 
been compared with those of the oscillations associated 
with straight wires, with open and closed circles and with 
closed ellipses. Definite numerical results have been 
obtained for circuits varying in length from 3 to 9 metres. 
In the appendix experiments are described which shew the 
effect of separating the ends of a circular resonator from 
each other, on the period of vibration induct or circuit, a 
point which has not previously been considered. 
Some remarks were made by Mr. G. H. Knibbs. 
2. “‘A contribution to the study of the Dielectric Constant 
of Water at Low Temperatures,’ by O. U. VON- 
WILLER, B.Sc.
