bunch or wrinkled swelling of the brest, eight semicircular scales, and a three forked taile. The swelling of the brest neere the head is white in some, in some it is distinguished with two black and blew spots, which are divided with a yellow line, and in severall ones it is seve∣rally made. For in some the colour is more remisse and watry, and not so visible, in others it is more deep. But where that bunch ris∣eth up, there are seen 4, knots, and the skin that is by them is wrink∣led. The half Circles follow. They are joyn'd with a very thin mem∣brane, as it were by a green line from blew. But the skales are white though in some of them there is somthing of a lead colour that shines under, and when the Silk-worms are ready for their Silkwork, they become of a spiceous colour, and all of them are marked with one spot on each side, with a little circle about it. I said there were bands, which appeare also in the Aurelia. Lastly the eighth scale is ei∣ther distinguished by two black and blew spots, or moonlike semi∣circles, which two half Moons one respecting the other with their horns are there inscribed. But they are not equall in all, for somtimes they are more conspicuous, somtimes more fading, fine, thin, lead co∣lour'd, white. Hence there are two small Circles, and that which follows these, hath two knots, untill that which is next the rump, and raiseth the tip or point; In the great ones there are observed bunchings forth in all the skales, but they are more eminent in the third skale. The skull is horny, but it is divided as it were into 3. parts, the right and left, which you would take to be marks of the eyes, and then the setting together of the mouth, which are again distinguished into the appendices and the jaws, wherein stand the saw-like teeth, The throat runs through all the length of the back, as farr as the props of the taile, upon which in the last skale is the end of the Belly. Also there are to be seen in the back, as far as the Plectrum of the tayle, some nervs moveable with a continuall pulsa∣tion, as the heart and arteries use to move, and these nervs are yel∣low from white, and when they are drawn asunder, they discover a green throat or intestine. They stick to the plectrum, as if there were some passage for breathing, though they do not breathe. But it is no doubt but there is the Seat of life, though I discovered in the young ones a kind of red part, as I shall shew underneath, beating by it self alone like the heart, when that plectrum is cut, a moyst yellowish liquour comes forth, and the Worms themselves do not dye, but they stirr the more violently, and roule and turn themselves that you will judge that they are in great pain, the nervous principle being hurt. The dung of them represents their meat, for it is dry with six corners long, as it were set with eyes, whence one may collect the disposition of the gut or belly. They are green from their food, but because they are hard, and without moysture, they seem black, as those that are more moyst seem more green. Here if you mark you may distinguish the males from the females. For the females here, as the Philosopher writes of other females are greater, fatter, moyster, softer, whiter than the males, which are more rude, more spotted 0
