7o Report of the President 



European blood among these Eskimo. This is an interesting 

 somatological discovery. We say traces of European blood 

 because that seems the most reasonable explanation of the 

 observed facts. 



Among the many minor investigations conducted in the 

 Museum may be mentioned a study of the composition of 

 copper implements from the Andean region of South America 

 by W. A. Wissler. Chemical analysis made it clear that the 

 production of bronze was understood by the ancient Peruvians. 

 A full report of this work will be published. 



Publications. — The results of research by members of 

 the scientific staff are issued in a special series, the Anthropo- 

 logical Papers of the American Museum of Natural History. 



Several papers were issued in the regular series, giving the 

 results of field work among the Crow, Blackfoot, Dakota and 

 Chipewyan tribes conducted by Doctors Wissler, Goddard and 

 Lowie. Frank E. Lutz of the Department of Invertebrate 

 Zoology reported some observations on the Patomana Indians 

 of British Guiana. A special series of handbooks was begun, 

 and the first number, on the Indians of the Plains, by Dr. 

 Clark Wissler, was issued. 



A special series of publications referring to the work of the 

 Jesup North Pacific Expedition is still being issued but con-

 whom are now on the Museum's staff. The editorial responsi- 

 bility for this work is borne by Professor Boas of Columbia 

 University. No volumes were issued during the year, but two 

 papers are now in press. 



Exhibition Halls. — As museum work is practically con- 

 tinuous, a report for the year is simply a cross-section of many 

 tasks begun during the previous year and extending over even 

 into the following year. This is especially true of exhibition. 

 At the beginning of the calendar year a small portion of the 

 Plains Indians Hall was in place and only a few cases in the 

 Woodlands Hall. As these two halls are now fairly well worked 

 out, all the space being occupied by the various tribes in their 

 proper sequence and position, it may be said that the year just
