skin, and finally, when full grown, it spins a ball of silk, called a
cone, or cocoon, the thread of which is about three hundred yards long:
in the centre of this ball the worm entombs itself, and experiences a
change to a state called an aurelia, or chrysallis, as seen below the
ball: from this aurelia, the moth that lays the eggs is hatched, and
thus goes on the round of this animal's changes, or transmigrations.

They are natives of China, and were brought into Italy, above twelve
hundred years ago; from thence into Spain; afterwards into France; much
later into Germany and the northern countries; and some have been reared
in the United States of America.




SAMUEL WOOD


Hereby informs the good little Boys and Girls, both of city and country,
who love to read better than to play, that if they will please to call
at his JUVENILE BOOK-STORE, NO. 357, Pearl-street, New-York, it will be
his pleasure to furnish them with a great variety of pretty little
books, with neat nuts, calculated to afford to the young mind pleasing
and useful information. Besides many from Philadelphia, New Haven, and
elsewhere, he has nearly fifty kinds of his own printing, and proposes
to enlarge the number.
