After the election of the new members the Academy, in joint ses- 

 sion with the Philosophical Society of Washington, listened to an 

 illustrated lecture on the Brownian movement and molecular reality by 

 Prof. Jean Perrin, of the University of Paris. It was explained that 

 the Brownian movement has furnished visible and experimental proof 

 of all the principal gas laws; that it has demonstrated the reality of the 

 molecular constitution of matter ; and that it has given four of the seven- 

 teen known independent methods of determining the number of gas 

 molecules per unit volume. 



The 88th meeting of the Washington Academy of Sciences, a joint 

 meeting with twenty other societies, was held in the hall of the Car- 

 negie Institution of Washington, Friday evening, December 5, 1913, in 

 memory of the late Dr. W. J. McGee. 



Mr. Frederick V. Coville presided and introduced the speakers, all 

 of whom had been intimately associated with Dr. McGee at some stage 

 of his career. Gifford Pinchot declared that much of the success 

 of forestry work was due to ideas advanced by Dr. McGee, and Dr. 

 Franz Boas, of Columbia University, read a paper analyzing the char- 

 acter and value of his work. 



Other speakers included Dr. Milton Whitney, N. H. Darton, 

 Henry Gannett, Col. H. C. Rizer, F. W. Hodge, and J. A. Holmes.
