That's the one point that a lot of his peers and colleagues didn't agree on, and the one point that was real controversial.
Dalton is stating that when atoms combine to form molecules, the ratio between the different atoms(elements) is one to one. Thus he believed water was OH instead of H2O. I don't really remember much but that's the gist of it. This final point was drawn from his previous points, even though Dalton had no evidence for it. I do know, however, that as of present day, at least four of his points still hold.
And Wikipedia isn't a reliable source for research...
