[Letters to Editor]

PROF. DART is under a misapprehension in supposing that I have in any way or at any time altered my opinion regarding the fossil ape discovered at Taungs. From the description and illustrations given by him (NATURE, Feb. 7, 1925, p. 195) the conclusion was forced on me that Australopithecus was a member of ``the same group or sub-family as the chimpanzee and gorilla'' (NATURE, Feb. 14, 1925, p. 234). In the same issue of NATURE, Prof. G. Elliot Smith expressed a similar opinion, describing Australopithecus as ``an unmistakable anthropoid ape that seems to be much on the same grade of development as the gorilla and chimpanzee without being identical with either''.
