DALTON 125 



there is a fresco, by Madox Brown, representing Dalton 

 collecting methane or marsh gas from a stagnant pool. 

 Opposite to Dalton's statue is one of Joule, by Gilbert. 

 These two statues are the most beautiful sculptures 

 Manchester possesses, and they commemorate the life- 

 work of two men who are to the northern city what 

 Shakespeare is to Stratford-on-Avon, or Kelvin to Glasgow. 

 In addition to these honours to Dalton's memory, there 

 are the Dalton chemical and mathematical scholarships 

 awarded by the authorities of the Owens College, Man- 

 chester ; and a street in Manchester bears his name. 



To conclude, the " atomic theory," in the words of 

 the celebrated French chemist Wurtz, " has thrown light 

 upon the most recent discoveries, as it has been, since the 

 time of Dalton, its immortal author, the most perfect 

 instrument in the most profound theoretical conceptions, 

 and the safest guide in experimental researches.''
