The angle between the asymptotes of a ray is developed as a power series in its impact parameter about some value which characterizes the `principal ray' When this value is zero, the principal points of the equivalent lens coincide at the axis of sym

The field asymmetries introduced in winding air‐cored solenoids are investigated theoretically by treating the solenoid as a suitably deformed single turn. Regarding the solenoid as an electron lens, aberrations are calculated for the various field

Cathode rays were deflected and focused in the median plane between a pair of similar coaxial solenoids Foci free of quadratic aberration were found at all pole separations and ratios of electron momentum to field strength, when the impact parameters

Details are given of an electron beam spectrometer using a magnetic deflection prism as a momentum analyser. The spectrometer is designed for the measurement, as a function of scattering angle, of the discrete energy losses of 10 keV electrons transm

Liebmann's method of tracing paraxial rays is critically reviewed, corrections being made to the higher terms of his formulae. A new and very accurate method of ray tracing is described, which is a development of that used by Burfoot; the predictor i

The measured e.m.f. of some saturated Weston cadmium cells is raised while an alternating current of a few microamperes is passing through them. The rise is approximately proportional to the square of the amplitude of the alternating current; over th
