Hello, Jacques,
Thankyou - can you explain how the Borda's Formula was applied?
The daily pages from the 'Cahier des Calculs' show workings for latitude each day, either by noon sight or by working up the DR. The weather at the time was very stormy so noon sights may not have been possible every day.
