ABSTRACT
This chapter includes early papers written in New Zealand, at the Cavendish Laboratory and during the Montreal period (1894-1906), as well as an introduction to Lord Rutherford's early work by Sir Edward Appleton, and some reminiscences of his time in Canada by Professors H. L. Bronson and Otto Hahn. The results given by Mr. Eve in this paper are supported by experiments which Lord Rutherford has made on the radioactivity of weak radium solutions. The quantity of radium in a cubic centimetre of the solution, measured by the amount of emanation produced by it, has not sensibly altered in the course of a year. Large number of experiments has been made by different observers on the rate of decay of the radioactive products, but in no case has the constant of decay of activity been changed by altering the degree of concentration of the products.
