During our voyage we had no lunar eclipses or like celestial phenomenas, we therefore determined our progress from the difference of longitude, which we ascertained by various instruments, by taking the sun's altitude from day to day, and by calculating geometrically the distance run by the ship from one horizon to another; all these observations, as also the ebb and flow of the sea in all places, were noted in a little book, which may prove serviceable to navigators; they are communicated to your Majesty in the hope of promoting science.
