Abstract
PROF. V. A. BAILEY has recently proposed1 an equation relating the electric charge on a star to the Newtonian gravitational constant and to the mass of the star. This equation has the form : 
where Q is the electrostatic charge, β is a dimensionless constant of approximately 0.03 for the Sun, G is the gravitational constant, and M is the mass of the star. For the Sun, Q turns out to be 1.5 × 1028 e.s.u. I wish to point out that equation (1) is closely related to a similar equation which I have obtained for the gravitational fields in the interior of fundamental particles (electrons and protons) by applying the Weyl theory of gauge invariance to the Einstein–Ricci curvature tensor.
