29 The Dielectric Polarisation of Liquid Mixtures. BY L. M, DAB, M. Bo., A8st. Lecturer, Dacca ITPsiamt6ty m 8, C. Rm, M. Bc. (Raceired tor pbIhtion, 10th Mag, f930.) Introductb, Ths moleoular polarisation of a subahnce in which the moIecules are h e  t o  asnme a perfeotly random mientation mn be expressed by the eqoation P-s.7 where E i8 the 6- eIwtric oonshut of the aabstance, M its rnoleunlar weight and p its denaity. Dabye theory1 introducee the molecular polarisation in the form P-A++ where A and B an, ho oon- a b t a  for the dielectriu ; A ia equal to moleonlar refraction "I-' ' extrapolated to  infinite wavelength and B is qd ta m; in whioh N=Avogsdro number, K=Boltamann gas con- stant and p = permanent electric moment of a einge molwnle forming e doublet. A includm tha polarisation due to ebotria ahifts induod in the molecnle while B inoludm the po lark  tion due to doublet orientation oaused by external field. In
