This is cool Mike. I see fore-runners of some of the rules we use now... interference, dislodged base,...
I noticed the part about the pitcher must deliver the ball where the striker wants it. I found this same "rule" on, I believe, a Popular Mechanics website discussing the origins of baseball. (There is some other interesting stuff there about curve balls, and cannon style pitching machines, etc.)
Just visited the site and it looks like you would have to perform a search to find these older articles but there is a bunch of baseball information there.

Thanks for the information about Rounders. Tony
