Note o — BOOK IV.
Reading edition
Besides the Pulices last mentioned, there are in the Waters other Animalcules very numerous, which are scarce visible without a Microscope. In May, and the Summer Months, the green Scum on the top of stagnating Waters, is nothing else but prodigious Numbers of these Animalcules: So is likewise the green Colour in them, when all the Water seems green. Which Animalcules, in all Probability, serve for Food to the Pulices Aquatici, and other the minuter Animals of the Waters. Of which I gave a pregnant Instance in one of the Nymphæ of Gnats, to my Friend the late admirable Mr. Ray, which he was pleased to publish in the last Edition of his Wisdom of God in the Creation, p. 430.
