Abstract
MR. PICKARD is interested in numbers, particularly primes and perfect squares. He points out that the ratio of the masses of the proton and the electron may be taken as 1849, and this is the sum of the consecutive primes from 3 to 131 inclusive; or as Mr. Pickard prefers to put it, the mass of the whole hydrogen atom is 1850, which is the sum of the first 32 primes, 2 being omitted. In an appendix he gives arguments in favour of omitting 2 from the list of primes. He also points out that 1849 = 432, and 43 is the sum of the terms in the bracket when the Rydberg Series is taken as far as corresponds to the completed series of the Periodic System.
