Cambridge Meeting of the British Association. 157 



The Reports of the Sections were then presented by the respective 

 Chairmen. 



Mr. Challis read a paper on the Theory of Fluids; in which he 

 treated of the leading hydrostatical and hydrodynamical problems; the 

 latter of which chiefly occupied his attention, and which he divided in 

 the following - manner : — 1st, the motion of fluids in vessels and pipes; 

 2nd, the determination of the velocity of the propagation of motion in 

 air ; 3rd, the musical vibrations of the air ; 4th, the theory of waves; 

 5th, resistance to a ball pendulum, supposing it to oscillate in a small 

 degree. 



The President announced, that since the preceding day, among the 

 names which had been enrolled by the Committee, were the names 

 of the illustrious Dr. Chalmers, Professor Jameson, and Dr. Henry, 

 sen., of Manchester; on each of whom he passed a high eulogium, 

 and who were then elected Members of the Association by acclama- 

 tion. 



He then stated that the Meeting for 1834 would take place at Edin- 

 burgh, in the month of September, probably in the early part of it; 

 and expressed his approbation of this determination of the Committee. 

 He observed, that it was not in consequence of its being the seat of a 

 University that Edinburgh had been selected: the Association was not 

 to be considered as an academic body. "We (said the President) 

 are citizens of'the world 3 we belong to (he republic of science, and 

 go to Edinburgh as a large capital, in the vicinity of a large manu- 

 facturing district." The Society, he observed, owed a debt of grati- 

 tude to Sir David Brewster and others, and were going to Edinburgh, 

 as dutiful children, to acknowledge it. u We have had a pressing in- 

 vitation," he concluded, "and shall have a cordial reception." 



It was afterwards announced that Sir Thomas Brisbane was the 

 President elect ; Sir David Brewster and Dr. Robinson the Vice- 

 Presidents ; the Rev. W. V. Harcourt, and Mr. Phillips of York, Ge- 

 neral Secretaries ; Mr. John Taylor, Treasurer. Dr. Robinson and 

 Professor Forbes, Secretaries/or Edinburgh ; and the Rev. W. Whewell 

 and Professor Henslow, Secretaries for Cambridge. He pronounced a 

 warm eulogium upon the President elect, who is the President of the 

 Royal Society of Edinburgh : he had fought for his country in time 

 of need ; and while Governor of a distant colony (New South Wales), 

 had established and carried on an observatory at his own expense. 



Professor Babbagenext addressed the Meeting on the subject of his 

 proposal for collecting and publishing the numerical quantities which 

 he has termed the Constants of Nature and Art ; of which we shall 

 give a further account in our next. 



Mr. Brunei, Earl Fitzwilliam, the Rev. W. Scoresby, the Marquis 

 of Northampton, the Rev. Dr. Lloyd, the President, Professor Buck- 

 land, Professor Hamilton, Professor Airy, Mr. Murchison, and the 

 Rev. W. V. Harcourt, having severally addressed the assembly, this 

 Third Meeting of the British Association for the Advancement of 

 Science was then dissolved by the President. 



In our next Number we purpose to give some additional particulars 

 of the scientific business transacted at this Meeting.
