ANTHROPOLOGY AT BALTIMORE. 
Srcrion H of the American Association 
for the Advancement of Science held its 
winter meeting at Baltimore, Maryland, on 
December 27th and 28th, in conjunction 
with the meetings of the American Society 
of Naturalists and Affiliated Societies. 
Vice-President Butler being unavoidably 
absent, Professor Franz Boas was elected 
temporary chairman at the Thursday morn- 
ing session which was called to order at 
SCIENCE. 139 
10.15 o’clock in the Historical Seminary 
Room at Johns Hopkins University. 
The first paper read was by Dr. Thomas 
Wilson, on ‘ Anthropological Congresses at 
the Paris Exposition of 1900.’ After a 
brief sketch of the history of the Congrés In- 
ternational d’Anthropologie et d’Archéolo- 
gie Préhistorique, Dr. Wilson gave a sum- 
mary of the work done at the recent ses- 
sions at Paris and described the field ex- 
cursion. An account wasalso given of the 
meeting of the Congres International des 
Américanistes. This Society has accepted - 
the invitation to meet in New York city in 
1902. On the motion of Dr. Wilson a com- 
mittee of three was appointed to take pre- 
liminary steps for the reception of the Con- 
gress at this, its first meeting in the United 
States. The committee appointed consists 
of F. W. Putman, chairman, J. W. Powell 
and G. A. Dorsey. 
The next paper, entitled, ‘The McCor- 
mick Expedition among the Hopi,’ by Dr. 
G. A. Dorsey, described the archeological 
work done along the Little Colorado River 
by a party from the Field Columbian Mu- 
seum and by another party in the vicinity 
of the Hopi pueblos. The ethnological i 
work of Mr. Voth was also described and 
commended. This paper will be published 
in SCIENCE. 
Professor Franz Boas next spoke of the de- 
sirability of a catalogue of the crania now in 
American museums. In order that the var- 
ious collections may be worked up ina uni- 
form manner, standard skulls should be sent 
to each museum from which the measure- 
ments tobe taken might be learned and the 
extent of error in observation reduced to a 
minimum. The Section was unanimous in 
its approval of Professor Boas’s plan and it 
was voted to refer the preparation of a re- 
port upon osteological cataloguing to the 
Anthropometrical Committee of the Asso- 
ciation. 
Dr. Frank Russell then demonstrated a
