The end of a _Sword-blade_ of _Olinde_, was burn'd, in 43.
A _Brass Counter_ was pierced, in 06.
A piece of _red Copper_ was melted ready to drop down, in 42.
{97}
A peice of a _Chamber Quarry-stone_ was vitrified,
and put into a Glass-drop, in 45.
_Steel_, whereof Watch-makers make their springs,
was found melted, in 09.
A _Mineral-Stone_, such as is used in Harquebusses
_a rovet_, was calcin'd and vitrified, in 1. _just._
A peice of _Morter_ was vitrified, in 52.

In short, there is hardly any Body, which is not destroyed by this Fire. If
one would melt it by it any great quantity of Mettal, that would require
much time, the Action of Burning not being perform'd but within the bigness
of the _Focus_, so that ordinarily none but small pieces are exposed to it.
One Mounsieur _de Alibert_ buys it, paying for it Fifteen hundred Livers.

Since this Information, there were, upon occasion given from thence, upon
the same subject, further communicated from _Paris_ the following
Particulars.

I see by two of the Letters, that you incline to believe, the Glasses of
_Maginus_ and _Septalius_ do approach to that of _Lyons_: But I can assure
you, they come very far short of it. You may consult _Maginus_ his Book,
where he describes his; and there are some persons here that have seen one
of his best, which had but about twenty Inches Diameter; so that this of
_Lyons_ must perform at least twice as much. As to _Septalius_, we expect
the Relations of it from Intelligent and Impartial men. It cannot well be
compared to that of _Lyons_: but in bigness; and in this case, if it have
five _Palms_ (as you say) that would be about 31/2 feet _French_, and so it
were a Foot bigger, which would make it half as much greater in surface:
But as to the Effects, seeing it burns so far off, they cannot be very
violent. And I have heard one say, that had seen it, that it did not set
Wood on Fire but after the time of saying a _Miserere_. You may judge of
the difference of the Effects, since that of _Lyons_ gathers its Beams
together within the space of seven or eight _Lines_; {98} and that of
_Septalius_ must scatter them in the compass of three Inches. Some here do
intend to make of them yea and bigger ones; but we must stay till they be
done, &c.
