1 In the 1944 Report, the article entitled "Southern Arabia, a Problem for the Future," 

 by Carleton S. Coon, pp. 385-402, is only a part of the larger article from which it was 

 reprinted. The complete paper can be seen in Papers of the Peabody Museum of American 

 Archaeology and Ethnology, Harvard University, vol. 20, Dixon Memorial Volume, 1943. 



In the same Report, in the article on penicillin by Florey and Chain, the reference to 

 footnote 2 on page 466 was inserted in the wrong place. Instead of following the words 

 "synthetic processes," it should appear after the last word on the page, "avoided."
