How about Chauvenet, A Manual of Spherical and Practical Astronomy, Philadelphia, 1863, Vol 2. Ch.4, Item 91, p103-104, for starters. This must have been fresh out of the printing press when you were young. By the way, I am deeply embarrassed to find out that in my last post I was only regurgitating what others have already elaborated in great detail. When I just read in Chauvenet, loc. cit. about the navigator "turning on his heel" (when swinging the arc) it rang a bell. Sure enough, on searching the list archives I find that Alexander Eremenko has posted a text by Maskelyne that says the same thing, and provided an analysis. Also Frank Reed has criticized Bauer in nearly the same words that I used, picking on the same passage. Apologies to all, sometimes it's difficult to remember what has been discussed on which forum. I withdraw from this discussion because everything that can be said is already in the archives. Herbert Prinz
