COMMITTEE ON ANTHROPOMETRIC MEAS- 

 UREMENTS. 



At the New York meeting of the Association phys- 

 ical and mental measurements were made of about 

 forty fellows of the Association, under the auspices 

 of this committee. The number is not sufiflcient to 

 permit of the publication of the results, but some 

 points of interest were disclosed. We are anxious to 

 continue these measurements, but cannot do so at 

 Denver owing to the difficulty of transporting instru- 

 ments and securing skilled assistance. We hope to 

 overcome the former difficulty in future by the con- 

 struction of instruments that can be packed in a 

 dress-suit traveling case. The sum of $50 appropri- 

 ated last year for the committee has been used in 

 constructing instruments with this object in view, a 

 balance and measuring rod having been made that 



can be readily transported. A traveling set of in- 

 struments of this character would be of value in 

 anthropological expeditions. 



The members of the committee resident in New 

 York have continued anthropometric work, measuring 

 the mental and physical traits of students of Colum- 

 bia and Barnard Colleges, and of children in the 

 schools. A thesis has been accepted for the degree of 

 doctor of philosophy in Columbia University by Mr. 

 Clark Wissler on 'The correlation of mental and 

 physical traits.' This thesis, which has been pub- 

 lished as a supplement to the Psychological Review, is 

 the iirst full treatment by quantitative methods of 

 the interrelation of mental and physical traits. Pro- 

 fessor E. W. Thorndike has also at Columbia Univer- 

 sity carried on experiments on the correlation of 

 mental ability, which will shortly be published. 



For the completion of the traveling set of anthropo- 

 metric instruments referred to, the committee asks a 

 further grant of fifty dollars.

REPORT OF THE COMMITTEE ON THE QUAN- 

 TITATIVE STUDY OF VARIATION. 



The grant of one hundred dollars to this Com- 

 mittee was used to help defray the expenses of Mr. C. 

 C. Adams, incurred in collecting for study molluscs 

 of the genus lo, found in the headwaters of the Ten- 

 nessee Eiver. A preliminary report has been made 

 by Mr. Adams, and this was printed in the Proceed- 

 ings of the Association for 1900. Mr. Adams submits at 

 this time a second report covering the results of study 

 on the material collected last summer, but prefers to 

 postpone further publication until after his final ex- 

 pedition, which he is making this summer. The main 

 results so far are that he has shown by the a'd of an 

 elaborate series of measurements that the numerous 

 species of lo run into each other in a very complete 

 way, and that the differences between the shells are 

 associated with their position up or down stream. 

 Nevertheless there is in most streams a more or less 

 marked discontinuity between the smooth, globular, 

 up-stream shells and the spiny, elongated down- 

 stream shells. The meaning of the discontinuity 

 (which justifies, in a way, a division of the she! Is into 

 two species) is still not perfectly clear. To test cer- 

 tain hypotheses in respect to this discontinuity, Mr. 

 Adams has returned to the field this summer. This 

 piece of work is, we believe, the largest and most 

 thoroughgoing quantitative study of the variation 

 of a species in nature that has yet been reported upon. 



The committee requests the Council to grant it one
