BEPO'BT OP NATIONAL MUSEUM, 1924 41 



Natural History, New York, have examined collections in the divi- 

 sion with a view toward comparison with material obtained during 

 their own explorations. During the course of his field work the 

 curator aided in the examination conducted by Dr. A. E. Doug- 

 lass, of Steward Observatory, University of Arizona, of the annual 

 tree rings in timbers found in prehistoric ruins. 



The curator of physical anthropology has carried on investiga- 

 tions on the morphology and racial characteristics of the teeth, and 

 the results were published in the American Journal of Physical 

 Anthropology. In addition, the curator has devoted a large part of 

 his time on the one hand to studies of 'ancient man, and on the other 

 to the completion of the studies carried on since 1912 on the old 

 Americans. The latter are practically complete and will be ready 

 for publication by the end of the fiscal year, forming a volume 

 of some 400 or 500 pages. There has also been prepared for publi- 

 cation and printed the first part of the catalogue of human crania 

 in the division collections.
