Referee's report by William Cecil Dampier Whetham, on a paper 'The electrical conductivity and other properties of Sodium Hydroxide in aqueous solution as elucidating the mechanism of conduction' by William Robert Bousfield and Thomas Martin Lowry Sectional Committee: Physics and Chemistry No clear statement regarding publication. Notes he was especially asked to consider the experimental part of this paper. On the whole the work seem to have been done carefully and accurately although one or two points seem open to criticism. One of the chief results of the paper depends on the use of a quantity which the author's name the 'instrinsic conductivity', which is the conductivity divided by the fluidity of the solution. No details are given of the method of determining the viscosity. If satisfactory answers are received from the authors on these two points, with some editing and contraction, the paper might be published. The diagrams might be much diminished in size and some omitted, without serious loss. Regarding the theoretical treatment Whetham discusses the use of the expression 'ionic mobilities'. Queries a point on page 89 regarding the increase in 'intrinsic conductivity' in concentrated solutions. [Published in the Philosophical Transactions A, 1905].
