Note f — BOOK IV. (continued 2)

The Ephemeron, as it is an unusual and special Instance of the Brevity of Life; so I take to be a wonderful Instance of the special Care and Providence of God, in the Conservation of the Species of that Animal. For, 1. As an Animal, whose Life is determin’d in about five or six Hours Time, (viz. from about six in the Evening, till about eleven a Clock at Night,) needs no Food; so neither doth the Ephemeron eat, after it is become a Fly. 2. As to its Generation; in those five Hours of its Life, it performs that, and all other necessary Offices of Life: For in the Beginning of its Life, it sheds its Coat; and that being done, and the poor little Animal thereby render’d light and agile, it spends the rest of its short Time in striking over the Waters, and at the same Time the Female droppeth her Egg on the Waters, and the Male his Sperm on them to impregnate them. These Eggs are spread about by the Waters; descend to the Bottom by their own Gravity; and are hatch’d by the Warmth of the Sun, into little Worms, which make themselves Cases in the Clay, and feed on the same without any Need of parental Care.
