 ACADEilY OF SCIENCES. 



The Iowa Academy of Sciences met for its 

 tenth Annual session in Des Moines, Janu- 

 ary 1st, 2d and 3d, 1896, in the Horticul- 

 tural rooms at the Capitol Building. The 

 attendance and interest at this meeting sui*- 

 passed all previous gatherings of the Ac- 

 cademy and were very encouraging. 



Prof. H. W. Norris in his address as re- 

 tiring President took for his subject 'Needed 

 Changes in Scientific Methods.' The ad- 

 dress was full of excellent suggestions, both 

 for scientific workers and for the public, 

 who look to scientific investigation for as- 

 sistance in economic problems. 



' The Homologies of the Cyclostome 

 Ear,' read by Prof. Norris, presented evi- 

 dence that the ear of Cyclostomes, though 

 difiering so markedly from that of ordinary 

 vertebrates, is still capable of being homolo- 

 gized perfectly with the ear in other orders. 



Prof. C. C. Nutting read a very interest- 

 ing paper on ' Origin and Significance of 

 Sex,' setting forth the theory of G-eddes and 

 Thompson as presented in their work on 

 the evolution of sex and detailing some 

 very interesting studies of his own on the 

 development and determination of sex in 

 Hydroids. 



Prof. T. Proctor Hall presented papers 

 on ' Unit Systems and Dimensions of Units,' 

 'Gravitation,' 'A Mad Stone.' In the last 

 paper he described a peculiar absorptive 

 power of the rock, being able to absorb 

 one-half more water bj"^ volume than the 

 rock itself. 



Prof. L. W. Andrews presented the fol- 

 lowing papers : ' The Influence of Moist- 

 ure on the Ignition Point of Sulphur,' and 

 ' The Eeduction of Sulphuric Acid as a 

 Function of the Temperature.' 



Prof. W. S. Franklin presented a paper 

 on 'A New Electrical Generator for Oxy- 

 gen and Hydrogen.' Prof. L. A. Youtz gave 

 an account of the Indianola clay and pot- 

 tery works. 



Prof. L. H'. Pammel gave an account of 

 the flora of Western Iowa, calling attention 

 to peculiar Western plants found on the 

 bluffs along the Missouri river. In a sec- 

 ond paper with Prof. F. Lamson-Scribner, 

 he enumerated the grasses found between 

 Jefferson, Iowa, and over the Rocky Mount- 

 ains — the gradual change from blue grass
