Rare Books: help, please~

I'd need your help with a book I don't get to find and maybe you know an English edition or something ^^; It's the Hou Han Shu and I'd be extremely grateful if someone could give me some clue about the book cause the only one I found is in Madrid and in Chinese :S

It'd be equally helpful if some of you knew the equivalence of an ancient chinese Li -I don't think at all that it's equivalent to a Roman mile @.@;

Thank you ♥

Pps: I left you with a pic of that kakemono I got *g*
