the questions of origin of designs and their 

 transmission from tribe to tribe. 



Discussion: Peet, McGee, Dixon, Boas, 

 Doi'sey and Hudson who gave reasons for 

 favoring Poma as against Ponio for the

 VariaMlity of Anthropometric Types: 



Franz Boas. 



The variability of organisms depends 

 upon the correlation of their elements. The 

 variability of the whole organism may, 

 therefore, be considered largely an expres- 

 sion of correlation of its constituent parts. 

 The greater the correlation of the parts 

 constituting an organ, or included in a 

 measurement, the greater will be its varia- 

 bility. Generally it is assumed that in- 

 dices are expressions of correlation. The 

 author demonstrated that they are not 

 necessarily so, but that regression is the 

 only sure test of correlation. The impor- 

 tance of the pathological method of study- 

 ing correlation is emphasized. Professor 

 Boas made free use of the blackboard as a 

 means of illustration. 

 The Somatological Investigations of the 



Hyde Expedition: Ales Hrdlicka. 



The Hyde Expedition comprises a va- 

 riety of anthropological investigations on 

 the peoples of the soiithwest, the whole be- 

 ing carried on under the direction of Pro- 

 fessor Frederick W. Putnam for the Amer- 

 ican Museum of Natural History, New 

 York City. The object of the somatological 

 work of the Hyde Expedition, of which Dr. 

 Hrdlicka is in charge, is to carry out a sys- 



tematic investigation, mainly of a physical 

 nature, on the extinct and living peoples 

 of that part of the United States and 

 Mexico Avhich had once been occupied by 

 the Pueblos with Cliff-Dwellers, and theTol- 

 tecs, Chichimecs and Aztecs. It is hoped 

 that these stiidies will establish the phys- 

 ical types of these peoples and show their 

 racial relations or diversities. The region 

 over which this research extends is 

 bounded approximately by the 38th paral- 

 lel in the north, by the Rio Grande and 

 the foothills Of the Sierra Madre in the 

 east, the Colorado River and Pacific Ocean 

 in the west, and the States of Mexico and 

 Michoacan in the south. It interlaces in 

 the south with the region, the tribes of 

 which were examined by Professor Starr 

 and, in the north and northwest, connects 

 with the field of work of the Jesup Expedi- 

 tion under Professor Boas. Dr. Hrdlicka 

 began the outlined investigations in 1896, 

 on the osteological material, principally 

 Tarasco, collected by Dr. Lumholtz. In 

 1898 the field work was begun by the study 

 of the tribes of Tarahumaras, Huichols and 

 Tepecanos in Mexico. On the second ex- 

 pedition, in 1899, the research was carried 

 on among the Utes and the Navahos, and 

 on the third trip, in 1900, the investigation 

 comprised the Mokis, Zuiiis, Rio Grande 

 Pueblos, all the divisions of the Apaches, 

 Mohaves and a branch of the Piutes. At 

 this moment Dr. Hrdlicka is starting on 

 the fourth expedition, on which probably 

 the field work Avill be completed. There 

 will be visited the Suppais and Hualapais, 

 Yumas, Pimas, Papagos, Yaquis, Tepe- 

 huanas, Coras, Aztecs, Tarascos and sev- 

 eral smaller tribes. The work of the ex- 

 pedition will probably occupy the larger 

 part of the coming year. The expenses of 

 this as well as those of the 1900 and 1899 

 expeditions are generously provided for by 

 Mr. Frederick E. Hyde, Jr., of New York 

 city.
