>>The book is interesting as it gives a method for reducing sights from not only >>the D.R. position as I learned in JN but also from an assumed position. >The methods you learned in JN will work just as well with an assumed position. True enough, I could use Ageton's H.O. 211 from an assumed position, but Ageton's 1961 book "Manual of Celestial Navigation" includes a second table (actually the first in the book with H.O. 211 as the second) which is used for the initial table entry in the sight reduction. It makes the tables twice as long, but simplifies the arithmetic a little. I have not seen this table elsewhere.
