In a recent paper Dr G. C. McVittie discussed the solution with axial symmetry of Einstein's new field-equations in his Unified Field Theory of Gravitation and Electricity. Owing to an error in his calculation of the field equations, Dr McVittie did not obtain the general solution, which we discuss in the present paper.

page 37 note 3 The summation convention applies to all indices which appear twice, except in formulae containing the coefficients e 3. If e 3 appears, a summation is to be understood only if the index s appears three times ; thus 
is not to be summed, but 
is.
