Page 2, Sect. 1. We since find, that the fire in the bottle is not
contained in the non-electric, but _in the glass_. All that is after said
of the _top_ and _bottom_ of the bottle, is true of the _inside_ and
_outside_ surfaces, and should have been so expressed. _See Sect._ 16, p.
16.

Page 6, Line 13. The equilibrium will soon be restored _but silently_, etc.
This must have been a mistake. When the bottle is full charged, the crooked
wire cannot well be brought to touch the top and bottom so quick, but that
there will be a loud spark; unless the points be sharp, without loops.

Ibid. line ult. _Outside_: add, such moisture continuing up to the cork or
wire.

Page 12, line 14. _By candle-light_ etc. From some observations since made,
I am inclined to think, that it is not the light, but the smoke or
non-electric effluvia from the candle, coal, and red-hot iron, that carry
off the electrical fire, being first attracted and then repelled.

Page 13, line 15. _Windmil wheels_, &c. We afterwards discovered, that the
afflux or efflux of the electrical fire, was not the cause of the motions
of those wheels, but various circumstances of attraction and repulsion.

Page 16, line 21. _Let_ A _and_ B _stand on wax_, &c. We soon found that it
was only necessary for one of them to stand on wax.

Page 24, line 12. r. contact, line 24. confined.

Page 25, line 10. for _stand_ r. _hand_.

Page 28, line 2. _The consequence might perhaps be fatal_, &c. We have
found it fatal to small animals, but 'tis not strong enough to kill large
ones. The biggest we have killed is a hen.

Page 31, line 20. _Ringing of chimes_, &c. This is since done.

Page 33, line 22. _Fails after ten or twelve experiments._ This was by a
small bottle. And since found to fail after with a large glass.

Page 40, sect. 50, 51. _Spirits must be heated before we can fire them_,
&c. We have since fired spirits without heating, when the weather is warm.

While I was intent on improving my language, I met with an English grammar (I think it was Greenwood's) having at the end of it two little sketches on the arts of rhetoric and logic, the latter finishing with a dispute in the Socratic method; and soon after I procured Xenophon's _Memorable Things of Socrates_, wherein there are many examples of the same method.

Encouraged, however, by this attempt, I wrote and sent in the same way to the press several other pieces that were equally approved; and I kept my secret till all my fund of sense for such performances was exhausted, and then discovered it, when I began to be considered with a little more attention by my brother's acquaintance.

"Now," said he, "Osborne never will allow the least merit in anything of mine, but makes a thousand criticisms out of mere envy: he is not so jealous of you; I wish, therefore, you would take this piece and produce it as yours: I will pretend not to have had time, and so produce nothing; we shall then hear what he will say to it.

Several persons were named, and for that reason not agreed to: at length one mentioned me, with the observation that I was merely an honest man, and of _no sect_ at all, which prevailed with them to choose me.

"After taking Fort Duquesne," said he, "I am to proceed to Niagara; and having taken that, to Frontenac, if the season will allow time, and I suppose it will; for Duquesne can hardly detain me above three or four days; and then I see nothing that can obstruct my march to Niagara.

The rites of hospitality were called _sacred_, because the stranger, the poor, and the weak, when they applied for protection and relief, were, from the religion of those times, supposed to be sent by the Deity to try the goodness of men, and that he would avenge the injuries they might receive, where they ought to have been protected.

But our frontier people call themselves Christians! They would have been safer if they had submitted to the Turks; for ever since Mohammed's reproof to Khaled, even the cruel Turks never kill prisoners in cold blood.
