Note 28 — INTRODUCTION.
Reading edition
Mr. Derham, speaking of the utility resulting from the observation of these phænomena, (in his Astro-Theology,) says—“As to the eclipses, whether of sun or moon, they have their excellent uses. The astronomer applies them to considerable services, in his way, and the geographer makes them no less useful in his: the chronologer is enabled, by them, to amend his accounts of time, even of the most ancient days; and so down through all ages: and the mariner, too, can make them serviceable to his purpose, to discover his longitude, to correct his account at sea, and thereby make himself more secure and safe in the untrodden paths of the deep.”
