Fred, you wrote: "I looked at the figure. If they could have had a good longitude, they would have been better off. " Did you look at the full diagram in the article? George clipped it just to the left of a couple of small X's in the original diagram. Do you see what those little X's represent?? They change EVERYTHING. That's where the Scillies would be relative the fleet's DR positions assuming something as trivial as a different catalogued source for the longitude difference between the Isles of Scilly and Cape Spartel. Longitude was the primary error in the fleet's position. -FER PS: I want to be very clear on this: I do not mean to imply that George clipped the diagram to remove the X's. He clipped it there, quite appropriately, to save on image size. However, I would contend that W.E. May made the X's small, and almost un-noticeable, in order to minimize their significance, which would have been a distraction from the point he (W.E.May) was trying to make. Diagrams were expensive back then, and he could not publish a dozen in one small article. Today, something animated could cover all the bases... --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To , send email to NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
