Referee's report by Max Born, on a paper 'Classical electrodynamics without singularities' by H McManus Sectional Committee: Mathematics Recommended for publication in the 'Proceedings of the Royal Society of London'. Was an external examiner for the paper when it was submitted as a PhD thesis. The paper is clear and well written, but very long and should be shortened, but cannot make definite suggestions for doing this. Provides detailed criticism of the mathematics. Suggests discussing potential shortening with the author or Rudolf Ernst Peierls. [Published in the 'Proceedings of the Royal Society of London'] No received date. [1948]
