CHAP. II.

Out of the Egg of the Ephemeron proceedeth a Six-Legged Worm.

THE Time when the Worm is hatched and named Aas, or Bait, being to me unknown; I will proceed in my discoveries; and first, if after some considerable time you dig in the Clay about the places where these worms are, you will find a great number of Six-legged and very small worms; which differ not in form and shape from those which are bigger: I said, a considerable time, because they grow but slowly, for in the following year in the month of Iune, when the full grown Worms shed their Skin, these Worms are in size but of about (a) one Holland inch long, viz. ⅓ part of the length of the (b) full grown Worm.

Besides these Two sorts of Worms so considerably different in size, there is at the same time also found in the Clay a (c) third sort, which exceed the smallest sort, being double the size of them, and are less than the full grown. Besides, those of each Size and Age dif∣fer somewhat in length and thickness among them∣selves. So that whereas the full grown Worm at the time that it is ready for flight is about Three Holland inches long, the middle sort are about Two of the same inches long, and the smallest about One inch.

There is also this further difference as to their Age, that those of the (d) first size have not only no wings, but also no appearance of them; but in the second size the (e) wing-cases appear, which in the third size are fully and plainly visible, (f) and as a flower in its bud, growing on, and as it were creeping out.
