On the Theory of Dispersion and Scattering of Light in Liquids 



By Louis V. King, D.Sc,

(Read May Meeting, 1922) 



Abstract 



The theory of dispersion and scattering according to the classical 

 electron theory is revised in the light of recent views as to the lack of 

 symmetry in the quasi-electric forces controlling vibrations in the 

 molecule. New dispersion and scattering formulae are obtained in 

 satisfactory agreement with recent observations. 



On the Electrical and Mechanical Characteristics of a New High 

 Frequency Vibration Galvanometer

(Read May Meeting, 1922) 



Abstract 



An account of the detailed characteristics of the 1000 cycle 

 vibration galvanometer described in a previous paper. The sensi- 

 tivity, sharpness of resonance, effective resistance and reactance at 

 various frequencies have been determined for the most recent design. 



On the Numerical Computation of Elliptic Functions 



By Louis V. King, D.Sc, 

 McGill University 



(Read May Meeting, 1922) 



Abstract 



Continuing previous researches on the numerical calculation of 

 the complete elliptic integrals of the first and second kind in terms of 

 the arithmetico-geometrical scale, new formulae have been found 

 which make it possible to evaluate directly by means of a modern 

 calculating machine not only the incomplete integrals of the first and 

 second kind, but also the various cases which arise in the discussion 

 of the incomplete third elliptic interval.
