A study has been made of the radioactive isotopes of scandium formed from calcium and potassium by bombardment with alpha-particles. ${\mathrm{Sc}}^{43}$ has been separated chemically from calcium, its half-life being 4.0\ifmmode\pm\else\textpm\fi{}0

The paper reports a study of certain induced radioactivities associated with potassium. It is shown that the half-life of ${\mathrm{K}}^{42}$ is 12.4\ifmmode\pm\else\textpm\fi{}0.2 hours. In addition to the well-established deuteron and slow neutron

A study has been made of the radioactivities induced in titanium and vanadium by irradiation with deuterons, slow and fast neutrons and in titanium with 11 Mev alpha-particles. Bombardment of titanium with deuterons renders it extremely radioactive,

A further study of the induced radioactivity of calcium has been made. It has been established that the 2.5-hour period previously assigned to ${\mathrm{Ca}}^{45}$ is in fact associated with ${\mathrm{Ca}}^{49}$. It is shown that this isotope probabl

THE existence of a neutron of mass 2 has been considered as a theoretical possibility by several physicists. The observations of Beck, that in the building up of heavier elements from the lighter, electrons are added in pairs, is of much interest and
