Thank you Fwiffo! I'm only a beginner in Latin, but I can make out some of the meaning. Rules 1 to 12 seem to correspond to the ones in English. Rules 13 seems to simply describe the layout of the muscovites, and I can't understand 14 at all yet, but I have a feeling that, like rule 13, it may have been excluded from the English edition simply because it duplicated information already given.
