yellow, his eyes black as jet, his forehead purple, his feet and hinder parts green, his tail two-forked and black, the whole body stained with a kind of red spots which run along the neck and shoulderblade, not unlike the form of Saint Andrew's cross, or the letter X, made thus cross-wise, and a white line drawn down his back to his tail; all which add much beauty to his whole body." And it is to me observable, that at a fixed age this caterpillar gives over to eat, and towards winter comes to be covered over with a strange shell or crust, called an Aurelia, and so lives a kind of dead life, without eating all the winter; and, as others of several kinds turn to be several kinds of flies and vermin the spring following, so this caterpillar then turns to be a painted butterfly.

Come, come, my Scholar, you see the river stops our morning walk, and I will also here stop my discourse; only as we sit down under this honeysuckle hedge, whilst I look a line to fit the rod that our brother Peter hath lent you, I shall, for a little confirmation of what I have said, repeat the observation of Du Bartas.*

God, not contented to each kind to give,
And to infuse the virtue generative,

By his wise power made many creatures breed
Of lifeless bodies without Venus' deed.

So the cold humor breeds the salamander,
Who, in effect, like to her birth's commander,
With child with hundred winters, with her touch,
Quencheth the fire though glowing ne'er so much.

So in the fire in burning furnace springs
The fly Perausta with the flaming wings ;
Without the fire it dies, in it it joys,

Living in that which all things else destroys.

in a foot note: "View Sir Fra. Bacon, Exper. 728 and 90 (the last a mis take of his printer, for 29 i. e. 729), in his Natural History." The reader will find much on this subject of interest to the angler in Ronald's Fly-Fisher's Entomology, London, 1836, a very beautiful and instructive book, though, to my judgment, carrying the theory of imitation too far.Am.
