braced the great section of quartzite with smaller exposures of 

 limestone and with intruded masses of eruptive rocks which 

 range from pronounced porphyries to granites. At least three 

 kinds of eruptives can be distinguished. The author described 

 in outline the faults and geological relations of the ores, and 

 stated that the ores especially favored the contact of the erup- 

 tive rocks with the quartzites. The evidences of contact meta- 

 morphism between the porphyries and the limestones were 

 commented upon. The ores in the great porphyry dike on the 

 claims of Colonel Wall were described, and were stated to be 

 secondary in their origin — that is, they probably were intro- 

 duced in solution into a mass of crushed eruptive rock. The 

 data for the paper were gathered in connection with the field 

 instruction given to a class of students the past summer. The 

 paper was illustrated by means of lantern slides, maps and 

 specimens. Edmund O. Hovey,

SECTION OF ANTHROPOLOY AND PSYCHOLOGY. 



October 27, 1902. 



Section met at S. 15 P. M. 



At the preliminary business meeting Professor Edward L. 

 Thorndike, of Teachers College, Columbia University, was 

 elected as Chairman of the Section for 1903. 



The program of the evening consisted of anthropological re- 

 ports of summer work. Dr. Clark Wissler described his re- 

 searches among the Sioux Indians in the interests of the Amer- 

 ican Museum of Natural History, paying particular attention to 

 their decorative art as compared with that of surrounding tribes. 

 Dr. A. L. Kroeber, of the University of California, spoke of the 

 field work carried on by that institution under his direction, 

 dwelling particularly upon the distribution of linguistic stocks 

 in California and the correspondence between linguistic and cul- 

 tured areas. 



Dr. Maurice Fischberg, of New York, outlined a study in 

 which he is engaged involving the measurements of, and collec-
