Nature of Positive Rays=== Positive rays were dis- covered by Goldstein in 1886 in electrical discharge at low pressure. In some experiments with a perforated cathode he noticed streamers of Hght behind the perforations. This luminosity, he assumed, was due to rays of some sort which travelled in the opposite direction to the cathode rays and so passed through the apertures i...")

What had been before regarded as a convenient working hypothesis became with remarkable rapidity a definite statement of fact. This transformation is now complete and in any well- equipped laboratory to-day not only can individual atoms be detected but the movements of the swiftest of them can be tracked and...")

This method was used in the early mass analysis measurements of Wien (1898), Thomson (1912), and Aston (1919). In 1921, Aston extended this method to use a heated anode and then a composite anode made of a paste of powdered carbon mixed with sample. Later in 1936 Bainbrid...")
