as some have thought, but that the Coating always
receives what is discharged by the Wire, or an equal Quantity; the
outer Surface being always in a negative State of Electricity, when
the inner Surface is in a positive State._

Place a thick plate of glass under the rubbing cushion, to cut off
the communication of electrical fire from the floor to the cushion;
then if there be no fine points or hairy threads sticking out from
the cushion, or from the parts of the machine opposite to the
cushion, (of which you must be careful) you can get but a few sparks
from the prime conductor, which are all the cushion will part with.

Hang a phial then on the prime conductor, and it will not charge
though you hold it by the coating.--But,

Form a communication by a chain from the coating to the cushion, and
the phial will charge.

For the globe then draws the electric fire out of the outside surface
of the phial and forces it through the prime conductor and wire of
the phial into the inside surface.

Thus the bottle is charged with its own fire, no other being to be
had while the glass plate is under the cushion.

Hang two cork balls by flaxen threads to the prime conductor; then
touch the coating of the bottle, and they will be electrified and
recede from each other.

For just as much fire as you give the coating, so much is discharged
through the wire upon the prime conductor, whence the cork balls
receive an electrical atmosphere.--But,

Take a wire bent in the form of a C, with a stick of wax fixed to
the outside of the curve, to hold it by; and apply one end of this
wire to the coating, and the other at the same time to the prime
conductor, the phial will be discharged; and if the balls are not
electrified before the discharge, neither will they appear to be so
after the discharge, for they will not repel each other.

If the phial really exploded at both ends, and discharged fire from
both coating and wire, the balls would be _more_ electrified, and
recede _farther_; for none of the fire can escape, the wax handle

But if the fire with which the inside surface is surcharged be
so much precisely as is wanted by the outside surface, it will
pass round through the wire fixed to the wax handle, restore the
equilibrium in the glass, and make no alteration in the state of the
prime conductor.

Accordingly we find, that

My mother, the second wife, was Abiah Folger, daughter of Peter Folger, one of the first settlers of New England, of whom honorable mention is made by Cotton Mather in his church history of that country, entitled Magnalia Christi Americana, as "a godly, learned Englishman," if I remember the words rightly.

I had made many a meal on bread, and, inquiring where he got it, I went immediately to the baker's he directed me to, in Secondstreet, and ask'd for bisket, intending such as we had in Boston; but they, it seems, were not made in Philadelphia.

My friend and companion Collins, who was a clerk in the post-office, pleas'd with the account I gave him of my new country, determined to go thither also; and, while I waited for my father's determination, he set out before me by land to Rhode Island, leaving his books, which were a pretty collection of mathematicks and natural philosophy, to come with mine and me to New York, where he propos'd to wait for me.

" These embarrassments that the Quakers suffer'd from having establish'd and published it as one of their principles that no kind of war was lawful, and which, being once published, they could not afterwards, however they might change their minds, easily get rid of, reminds me of what I think a more prudent conduct in another sect among us, that of the Dunkers.

There was, indeed, little or no money at that time in the office, and therefore I propos'd that the orders should be payable in a year, and to bear an interest of five per cent.

When they enlisted, they were promised, besides pay and provisions, a gill of rum a day, which was punctually serv'd out to them, half in the morning, and the other half in the evening; and I observ'd they were as punctual in attending to receive it; upon which I said to Mr.

I recollected that about 20 years before, a clause in a bill brought into Parliament by the ministry had propos'd to make the king's instructions laws in the colonies, but the clause was thrown out by the Commons, for which we adored them as our friends and friends of liberty, till by their conduct towards us in 1765 it seem'd that they had refus'd that point of sovereignty to the king only that they might reserve it for themselves.
