Referee's report by John Ambrose Fleming, on a paper 'The action of magnetised electrodes upon electrical discharge phenomena in rarefied gases' by C E S Phillips Sectional Committee: Physics & Chemistry Recommended for publication in Philosophical Transactions, in full. Modifications are not necessary as the paper describes chiefly experimental results. All the illustrations should be reproduced. The paper is a valuable one and describes a new and very interesting discovery connected with electric discharge in rarefied gases. [Published in Philosophical Transactions A, 1901].
