Here's a list of resources I consulted, but in the end didn't cite. Very many of these were thanks to Google Books, which hugely extended the reach of my research; in those cases I'll link directly to them.
btw, I've just finished (skim-) reading Anglo-Chinese Encounters since 1800: War, Trade, Science, and Governance by Wang Gungwen (Cambridge University Press: 2003) - a short and lucid outline of the recent histories of Britain and China. Don't be fooled by any of this into thinking I've suddenly become an expert; I only found out (from reading Professor Wang's book yesterday) where Malaya is, and that Singapore is a whole country. *脸 手掌*
