arts and customs, and especially of their 

 physical structure. He regards them as in- 

 ferior in every way to the adjoining E"ava- 

 jos ; considerable uniformity of physical 

 type prevails throughout the various bands 

 composing the tribe. Dr. George T. Ste- 

 vens exhibited a number of pieces of appa- 

 ratus for testing the vision, and spoke of 

 ' The pose of the body as related to the type 

 of the cranium and the directions of the 

 planes of vision.' Dr. Stevens also exhib- 

 ited a number of lantern views illustrating 

 the abnormal poise of the head that results 

 from the adoption of an incorrect plane of 

 vision , which he believed to be in some meas- 

 ure due to the shape of the eye socket, rep- 

 resented in craniometry by the orbital index. 

 An exhibit of stereoscopic and triple-color 

 slides was made by E. W. Scripture, who 

 also took the occasion to give the first pub- 

 lic demonstration of his method of produc- 

 ing anassthesia by an alternating electric 

 current of moderately high frequency and 

 without drugs of any kind. 



The morning session of Thursday opened 

 with a paper by Vice-President Wilson, en- 

 titled ' Similarity of thought not neces- 

 sarily evidence of similarity in culture,' in 

 which he dwelt more particularly upon the 

 evidence obtainable among the higher 

 civilizations — the evidence from the more 

 primitive cultures having been presented in 

 his address at Columbus. Dr. Wilson's in- 

 vestigations lead him to the conclusion 

 that striking similarity or identity of 

 thoughts is extremely rare in literature. 

 G. F. Wright exhibited a number of speci- 

 mens from Ohio, one of which, a ' Flint 

 core with supposed artificial chippings 

 found in the undisturbed gravel of the 

 Tuscarawas Valley, at Massillon, Ohio.' 

 George H. Pepper read a paper entitled 

 ' Mosaic objects from Pueblo Bonito' that 

 described the ceremonial objects inlaid with 

 jet and turquoise, which have been found 



among the ruins of the Chaco caiion by the 

 expedition organized by Messrs. B. T. B. 

 and F. E. Hyde and under Mr. Pepper's 

 direction. 



Dr. D. A. Sargent presented the results of 

 an extended investigation of physical corre- 

 lations among Harvard students, particu- 

 larly with reference to the ' Relation of 

 height, weight, and strength to the cep- 

 halic index'. The dolichocephalic men were 

 shown to be taller, heavier and stronger 

 than the brachycephalic. In the discussion 

 it was pointed out that this was in a great 

 measure due to the fact that within the 

 group the tendency is always toward doli- 

 chocephaly in the taller individuals and, 

 furthermore, that the environment of the 

 descendants of the earlier immigrants of a 

 dolichocephalic stock was much more favor- 

 able than that of the other group. Frank 

 Russell presented a preliminary paper upon 

 ' Some cranial anomalies. ' His investiga- 

 tions were made upon a series of over six- 

 teen hundred crania of the America.n race, 

 the percentages of occurrence of the various 

 anomalies were tabulated, and the results 

 presented a statistical form. George G. 

 MacCurdy exhibited a number of ' Iron 

 figurines from Styria ' and described the 

 character and distribution of this curious 

 survival of primitive superstition. 



The short afternoon session of the Section 

 was devoted to the paper presented jointly 

 by F. W. Putnam and G. F. Wright upon 

 ' A human bone from the Trenton Gravels. ' 

 This important discovery must effectually 

 silence many of the opponents to the theory 

 of the antiquity of man in the Delaware 

 Valley. The bone was found on the first 

 of December, 1899 ; it is a section of a 

 human femur, showing traces of having 

 been artificially worked. It was found in 

 the stratified and undisturbed gravels seven 

 feet below the surface, at the margin of a 

 canal that is being cut through the plateau,
