 Congress of Mathematicians 



It is announced that a series of lectures on the present condition 

 of the principal branches of mathematical science will be delivered 

 by representative mathematicians of different countries at the Fourth 

 International Congress of Mathematicians, to be held in Rome, 

 April 6 to 10, 1908. Professor Simon Newcomb, II. S. N., has been 

 requested to represent the Smithsonian Institution at this congress

Naples Zoological Station 



Dr. Stewart Paton, formerly of Johns Hopkins University, whose 

 occupancy of the Smithsonian seat in the Naples Zoological Station 

 was extended through June of the present year, is now preparing a 

 report of his research on the nervous system and its relation to the 

 cardiac movements, for publication in parts. The whole work will 

 be issued later in monograph form. 



Professor Maynard M. Metcalf, of the Woman's College, Balti- 

 more, occupied the Smithsonian seat at the station during the months 

 of March and April, and has submitted an interesting report of his 

 work while there. The research of Dr. Metcalf will be continued 

 at Wiirzburg, Bavaria, and a summary of the results will be pub- 

 lished on its completion. 



Hodgkins Fund 



Interesting researches aided by grants from the Hodgkins Fund 

 of the Smithsonian Institution are now in progress. 



Professor W. P. Bradley, of Wesleyan University, is still con- 

 ducting an investigation on the factors which make for efficiency in 

 the liquefaction of air. It is expected that the present work will be 

 completed and reported on during the present year. 



Mr. S. P. Fergusson, of Blue Hill Meteorological Observatory, 

 has submitted a summary of his investigation of the differences
