CCL: Dirac's famous statement

 To the CCL community:
 The following statement by the great British theoretician P. A. M.
 Dirac is frequently quoted in textbooks and papers:
 "The underlying physical laws necessary for the matematical theory of
 a large part of physics and the whole of chemistry are ... completely
 known"
 He should have made this statement in 1928 (or 1929), and, according
 to my notes, he should have continued: "The difficulty is only that
 the exact application of these laws leads to equations much too
 complicated to be soluble.  It therefore becomes desirable that
 approximate practical methods of applying quantum maechanics should
 be developed, which can lead to an explanation of the main features
 of atomic systems without too much computation"
 I would like to read the original source of these interesting
 remarks, apparently made only some months after the birth of quantum
 mechanics.  But where did Dirac publish his famous statement?
