[12 piece bucket]

I don't have the time to post to this right now- but I would say that you haven't translated it correctly. Hopefully I can get back to this later tonight but in the meantime- Here are three important clues 1) You need to take into account the entire context of the paragraph- you can't pull out a line of this paragraph by itself- that would be a complete misquote, and 2) If you use all of the clues possible that Mr. Kelley provided then it is crucially important that you look at his use of fonts and capitalization and 3) Understand that he understood at that time the "two" theories of head still and rotating around the spine- I might be going out on a limb but I would suggest that you read the paragraph as if he is addressing those two different camps- and clarifying his position on that point.
Maybe someone can put the entire paragraph up in it's entirety and EXACTLY as he typed it- as a starting reference point.

I'll type it up tonight . . . Mikey . . . wonder if the 8th edition will have anything on Rolling Heads or Defrosting Heads?
