ANTHROPOLOGICAL WORK AMONG THE INDIAN 

 TRIBES OF THE SOUTHWEST. 



N January i Dr. Ales Hrdlicka, of the Department 

 of Anthropology, started on his fourth expedi- 

 tion for this Museum to the region of the Aztecs, 

 Pueblos and Cliff-Dwellers, and he expects to re- 

 turn in about eight months. 



These expeditions have had for their object the systematic 

 study of the physical characteristics of all the Aztec, Pueblo 

 and Cliff-Dweller tribes, living or extinct, from southern Utah 

 and southern Colorado down to the state of Morelos, Mexico. 

 Among other results which may be expected are the definite 

 identification of these tribes and either a refutation or a con- 

 firmation of the theory that the Aztecs came from the north 

 and were probably related to the Pueblos. Physiological obser- 

 vations are also made for a comparison of some of the principal 

 functions of the body, such as pulse, temperature, respiration 

 and muscular force, in these tribes and in white men. Medical 

 observations are made on the ordinary diseases among the Indians 

 and on their manner of treating them. 



Dr. Hrdlicka 's previous expeditions in this series have been 

 as follows: first, in Mexico, in 1898, with Dr. Carl Lumholtz, 

 covering the Tarahumares, Huichols and Tepecanos; second, in 

 1899, to the Navahos and southern Utes; third, in 1900, to all 

 the Pueblos and Apaches. The present expedition will co\'er the 

 remaining tribes in southwestern Arizona and northern Mexico, 

 among them the Bimas, Papagos, Yaquis, ]\Iayos, Tepehuanes, 

 Coras, Aztecs and Tarascos. The first expedition was sup- 

 ported by the Museum ; the second, third and fourth by Mr. 

 Frederick E. Hyde, Jr.
