==Leading oxen...etc== 
 Sorry to have been so long, but I have started to assemble comments relating to the above. I'm working from a print copy; unfortunately, my printer renders some characters as hieroglyphics, making it hard to read and slowing me down. If I'm too late, please let me know and I'll desist! Otherwise, my comments can be found here. My daily online time is rather limited at present, but I hope to finish commenting in a couple of days or so. Meanwhile, I hope that your arm is recovering. I see a new coin has appeared at FAC, and I'll get to that next week.
