and "A classification of arrowpoints, spearheads, and knives of pre- 

 historic times." He was present at the Congress of Ethnology, and 

 was presiding officer during one day. At the ( longress of American 

 ists he presented a paper on "Jade in America." These various com- 

 munications were translated into French, and left, with the accessary 

 illustrations, in custody of the proper committees for publication. 



On his return from Paris he prepared a summary of the reports 

 of proceedings of the International Congresses of Anthropology and 

 Prehistoric Archeology and of the Congress of Americanists, which 

 were sent to Prof. J. H. Gore, commissioner, to be transmitted by him 

 in his formulation of the reports of Air. Ferdinand Peck, United States 

 commissioner to the Paris Exposition of 1900. 



Dr. Wilson has completed a translation into French of his paper on 

 " The antiquity of the red race in America," which appeared in the 

 U. S. National Museum Report for 1895, and this translation has been 

 published in LTAnthropologie for the current year (p. 11), under the 

 title of "L' Antiquity des peaux-rouges en Amerique." 



A paper on " Criminology " was read by him before the American 

 Association for the Advancement of Science at its forty-ninth meeting, 

 in New York. June, 1900, and has been published in the proceedings 

 of that association for 1900. 



His investigations into prehistoric trepanation have been continued, 

 andhis paper on that subject has been completed and presented for 

 publication b}^ the Museum. 



He was engaged during the year, at the request of Mr. H. R. Bishop, 

 of New York City, in the preparation of a paper on "Jade," which is 

 now completed and will shortly be ready for publication. 



Dr. Wilson has been interested in determining, so far as possible, 

 the truth of the- allegation that prehistoric man was ambidextrous. 

 He has obtained from the Carlisle and Hampton schools reports as to 

 the proportion of right and left handedness among the tribes there 

 represented. In continuation of this subject he has made a considera- 

 ble examination of such prehistoric tools and implements as are con- 

 tained in the Division of Prehistoric Archeology, with a view of 

 determining the proportion each way. Nearly all of these tools were 

 adapted to either hand; hut the hatchets or gouges made of the fulgur 

 shell and used with a handle which had been inserted afford a basis for 

 comparison, and the study of these has been nearly completed. 



Explorations conducted for the purpose of enriching the collections 

 of the Museum have been made by members of the Museum stall and 

 other experienced collectors. The head curator visited the vicinity of 

 Mill Creek, Union County, Illinois, to join Dr. W. A. Phillips, of the 

 Field Columbian Museum, in the examination of the very extensive 

 and important flint quarries at that place. A large collection of imple- 

 ments and of quarry shop rejectamenta of numerous varieties was
