Subject: Ageton & HO 211

The Hydrographic Office first published HO 211 in 1931. Ageton
invented this sight reduction method.
Someone named Weems devised the "New Line of Position Tables" around
the same time. This method required an assumed position such that LHA
and latitude were integers. It was not published until 1943.
Ageton published his "Manual of Celestial Navigation" in 1942,
including the first Weems table as Table I and the HO 211 table as
Table II. Did he give any credit to Weems?
All the above info is from Bowditch. I like reading the chapter on
the history of various sight reduction methods. Sad to say, I think
that story is over. Get your copies of HO 229 while it's still in
print! We'll never see anything like it again.
