Much of the mathematical detail of the paradox resolution of this paper had its origin in discussions with Dr. George Stranahan, and I am indebted to him for his helpful and critical persistence toward a solution. I thank Prof. Sir Brian Pippard for kindly extending to me during the year 1975–1976 the hospitality of the Cavendish Laboratory, where this paper was written.
