Description

Henry Oldenburg here comments on someone else's suggestions for calculating longitude on the basis of the sun and a star.

Although the text mentions the Italian astronomer Giovanni Battista Riccioli (1598-1671), Oldenburg seems to imply that he is not directly commenting on his book Geographiae et hydrographiae reformatae (Bologna, 1661)
