into a Grey colour; and yet more certain, when the Wing-cases can be separated from the Wings, without hurting them; as in Tab. 3. (hhh) is represented, where the Wing is represented at large with its natural but rare pleatings.
A further sign thereof is, when Dissecting the Worm the Eggs are found to be full grown, hard, and Oval, and also when the outward case may be clearly separa∣ted from the Worm and thereby cause it to attain the form of the flying Haft or Ephemeron.
At this time all their Intestines are cleared of all faeces; the Stomach and Guts containing nothing but transparent and purified liquor, which the further from Change they are, the more Clouded and Coloured they are found; their Colour being sometimes Yellow∣ish, and sometimes dark and Russet; at other times there is found backward in the thick and straight Gut a little Clay, whereas being now ready for Change, they are very clear and transparent.
That which retardeth the Change of the Worm, killeth it, and hindreth its Change, is a hard and long Winter, much Snow and Rain, whereby their Cells are closed, broke, or covered with Sand, whereby they come forth both fewer in number, and later in the one year than the other. They are also hindred by too much drought, which forceth them to leave their Cells, and bore new ones, from all which may be discerned what hindereth or furthereth the Worms growth.
Many water and other Insects are found to be infested with Li••e; which extendeth so far, that even no Creature living either on Land or Water, that hath not its peculiar Louse, which feedeth on its bloud and moisture, even from the great Whale to the small Ant.
From what hath been now related of the Signs of the full growth of the Worms Wings, it clearly ap∣peareth to which of the Four Orders of Natural Change, or slow growing on of the Limbs it pertain∣eth; viz. to the Second Order, for all the Insects there∣unto
