can be made into Portland cement; Mr. C. 

 Mercader, of the Carnegie Works at Pitts- 

 burgh, will for the first time in public de- 

 scribe the plant for manufacturing hoUow 

 pressed axles for railroads. 



The subject for the Adams prize of Cam- 

 bridge University, open to all persons who 

 have at any time been admitted to a degree, 

 is : " Wave motion of finite amplitude and 

 unchanging type, in deep water. Hitherto 

 only one type of such motion has been discov- 

 ered, that of Gerstner and Eankine, which 

 involves vorticity; it is suggested that on ex- 

 amination this might be found to be a special 

 case of a more general solution. No exact 

 solution has hitherto been obtained in which 

 the motion is irrotational ; it is desirable that 

 the question should be examined whether the 

 known approximate solution is in fact an ap- 

 proximation to a permanent state of motion. 

 In default of a conclusive answer to the above 

 questions, any considerable advance in the 

 theory of the subject, apart from an extension 

 of the known approximations, is desirable." 

 The successful candidate will receive about 

 £225. The essays must be sent to the vice- 

 chancellor on or before December 16, 1904. 



In accordance with the provisions of the 

 charter, the by-laws of the British Academy 

 have been allowed by the Privy Council. The 

 by-laws regulate the number of fellows, the 

 council, sectional committees, general meet- 

 ings, election of fellows and preliminary ar- 

 rangements. The number of ordinary fellows 

 is fixed at one hundred as a maximum limit, 

 but it shall not be necessary to complete that 

 number. The International Association of 

 Academies has unanimously agreed to the ad- 

 mission of the association as a constituent 

 academy in the philosophico-historic section. 

 Lord Eeay (president of the academy) has 

 been nominated by the academy as a member 

 of the International Council. Mr. Bryce, Sir 

 E. C. Jebb and Professor Pelham have been 

 appointed to represent the academy at the 

 forthcoming International Congress of His- 

 torical Studies, to be held in Rome. The 

 fellows of the academy are distributed under 

 four main sectonal committees, each section 



having its own chairman: (1) History and 

 Archeology, chairman, Mr. Bryce; (2) Philol- 

 ogy, chairman. Sir E. C. Jebb ; (3) Philosophy, 

 chairman. Dr. Edward Caird; (4) Jurispru- 

 dence and Economics, chairman. Sir C. P. 

 Ilbert. 



The International Agricultural Congress 

 was inaugurated at Eome on April 13 in the 

 presence of E^ng Victor Emmanuel and 

 Queen Helena. About 1,300 delegates were 

 present. The American representatives are 

 Dr. Daniel E. Salmon, chief of the United 

 States Bureau of Animal Industry, and Henry 

 E. Alvord, chief of the Dairy Division of that 

 bureau. 



A Universal Exposition of Sciences, Arts 

 and Industries will be held at Liege, Belgium, 

 in the year 1905. 



The American Electrochemical Society 

 held its third general meeting in New Tork, 

 on April 16 to 18. 



The Spokane Science Club, of Spokane, 

 Wash., held a meeting on March 10, at which 

 papers were read by Mr. J. T. McMuUen, on 

 DeVries' mutation theory and Mendel's law 

 and by Mr. E. Charming Moore on the hydro- 

 carbons. The correspondent who sends us 

 this information calls attention to the value 

 of such local clubs for scientific study and 

 urges their establishment wherever possible.
