open neck toell jar, or better, the dome of a porce- 

 lain vacuum evaporating apparatus fitted to the 

 body with a rubber gasket forms the top of the 

 pan. Through the upper rubber stopper passes 

 the connection to the condenser. The apparatus 

 is very eflieient and may be used for all sorts of 

 evaporations under diminished pressure.

THE AMERICAN MATHEMATICAL 

 SOCIETY 



The two hundred and tvrenty-fourth regular 

 meeting of the American MathemaAical Sodeity 

 was held at Columbia University, New York 

 City, extending ithrough the usuail morning ajid 

 afternoon sessions. The afctemdance moluded 

 forty-eight members of the society. The seere- 

 tiary announced the election of twentyone per- 

 sons to membership in the society; twenty-two 

 applications for membei-ship were received. 



At the meetimg of the Council, a list of nomi- 

 nations for ofiicers and other members of the 

 Council was presented by the Committee on 

 nominations, and was unanimously accepted. 

 Ex- Secretary F. N. Cole, who has sei-veid twen- 

 ty-five ye'ars as secretary of the society, was 

 'nominated for the presidency. Secretary Rich- 

 ardson reported that Professor. C6le, while ap- 

 preciating the honor done him by the nomina- 

 tion, found himself unable, on account of the 

 condition of his health, to accept. The CouncU 

 with regret accepted his decision, and adopted 

 an alternative nomination presented by the 

 committee. The following resolution was 



We, the Council of the American Mathematical 

 Society, desire to place on record an expression 

 of our profound regret that Professor Cole feels 

 compelled because of ill health to decline the 

 nomiuation to ithe presidency of the Society. We 

 believe that the members of the Society in general 

 will share our disappointment that the opportuni- 

 ty is thus denied us to confer on Professor Cole 

 tihe honor which would most suitably express our 

 high esteem of him and of his signal services to 

 the Society. 



The Committee on the Cole Fund presented a 

 report recommending that the fund be used to 

 endow a prize to be called the Frank Nelson 

 Cole Price in Algebra. The recommendations, 



which appear elsewhere in Science, were ac- 

 cepted by the Council.
