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, Manchester; and a street in Manchester bears his name.
