I found a book:
S. de Neuf:ville:
"La Navigation Sans Logarithmes"
Paris 1950
The book presents a graphical solution to Saint Hillaire by means
of diagrams spread over 64 pages with a resolution of 5 to 10 sm.
Unfortunately, it does not describe the mathematical background
but it credits "Favet" and "Rollet de L'isle". I do not know anything about them.
and the internet is silent about them.
However, I am interested in finding out about the math.
Does anyone remember reading about their approach?
Your help would be appreciated
