furnished a list of five species and two genera, 

 in addition to which were a number of imper- 

 fect specimens, representing about five addi- 

 tional species. The discoveries were highly- 

 satisfactory, and furnished the proof that had 

 been confidently expected. The specimens 

 collected were exhibited. 



The second paper was by Prof. J. F. Kemp 

 on the Glacial or Post-Glacial Diversion of the 

 Bronx river. The speaker showed that the 

 Bronx river from its source to Williamsbridge 

 follows an old valley, excavated in limestone. 

 This valley continues from a point below Wil- 

 liamsbridge to its end, on the Sound opposite 

 Randall's island and there is a depression the 

 entire distance. Just below Williamsbridge, 

 however, the river turns from its old valley 

 and breaks through a ridge of enclosing gneiss 

 on the east. It has excavated a gorge about 70 

 feet deep, with large fresh pot holes remaining 

 on the sides, respectively at altitudes of 20 and 

 50 feet above the stream. The maximum 

 height of the divide between the present chan- 

 nel and the older one is only 10 to 15 feet. The 

 speaker found difllculty in accounting for the 

 diversion, in that no barrier of gravel or other 

 deposit is visible along the line of the old chan- 

 nel, which would turn the stream from this 

 across the high ridge in which is the gorge. 

 The freshness of the pot holes indicated that 

 the stream had cut the gorge during the glacial 

 times and since then. He therefore referred 

 the diversion to the ice of the continental 

 glacier a lobe of which must have filled the 

 earlier channel. It is probable that the early 

 excavation was done by a sub-glacial stream, 

 heavily loaded with sediment. 



The third paper of the evening was by D. H. 

 Newland on the Eclogites of Bavaria, The 

 speaker described the extent and mineralogy 

 of the rocks and his attempts to discover their 

 unmetamorphosed originals. Chiefly on chemi- 

 cal analysis he was led to infer that they had 

 been originally diabases or gabbros.

SECTION OF ANTHROPOLOGY, PSYCHOLOGY AND 

 PHILOLOGY, OCTOBER 26, 1896. 



The Academy met with Prof. F. H. Giddings 

 in the chair. The Sub-section of Psychology 



and Anthropology immediately organized and 

 the following papers were presented : 



J. McK. Cattell, 'On Physical and Mental 

 Measurements of Students of Columbia Univer- 

 sity. ' This paper described the results of a series 

 of tests that has been made in conjunction with 

 Dr. Farrand on students of Columbia University 

 during the past two years. The members of 

 the Freshmen class were requested to come to 

 the psychological laboratory, where their phy- 

 sical, psycho -physical and mental traits were 

 tested. An hour was given to each student, 

 10 records and 26 measurements being made. 

 The tests selected, the methods of making 

 them, and the results were described. Special 

 stress was laid on the value of such work in the 

 study of development and of the correlation of 

 physical and mental traits. The paper will ap- 

 pear in full in the current (November) number 

 of The Psychological Review. 



Franz Boas, ' On the Limitations of the Com- 

 parative Method in Anthropology. ' This paper 

 will appear in full in an early number of 

 Science. Livingston Farrand, 



Secretary of Subsection.
