SECTION OF BIOLOGY OF THE NEW YORK 

 ACADEMY OF SCIENCES. 



At a regular meeting of the Section held on 

 May 13, Professor C. L. Bristol presiding, the 

 following program was offered : 



R. Weil : ' A Contribution to the Problem of the 

 Ear-Bones.' 



A. G. Mayer : ' On the Variation of Snails of the 

 genus Partula in the Valleys of Tahiti.' 



0. S. Strong : ' A Case of unilateral Atrophy of 

 the Cerebellum.' 



Dr. Weil's paper was a critical discussion of 

 the theory of the ear-bones, as embodied in the 

 recent articles of Kiugsley and Gaupp, Two 

 main contentions were considered : first, that 

 the malleus and incu&of mammalia were homol- 

 ogous with the quadrate and articular of lower 

 forms, while the temporo-maxillary articula- 

 tion is a new formation ; second, that the ossi- 

 cles of mammalia cannot possibly have de-
