1. The following proof of Bateman's expansion may be of interest since it avoids the use of Appell's hypergeometric functions of two variables, though it suffers from the defect that it presupposes a knowledge of the expansion.

† See Watson, , loc. cit., § 4·42. The use of the symbol is necessary, since one of the parameters in the denominator is a negative integer.Google Scholar
* There is no great difficulty in justifying the implied change in the order of summation. The argument is similar to that used by Watson, loc. cit., p. 400.
