thing, in effect, that
is here mentioned; and hath practised it for many years. That is, he is
able so to apply a colour to the outside of polished Marble, as that it
shall sink a considerable depth into the body of the stone; and there
represent like figures or images as those are on the outside; (deeper or
shallower according as he continues the application, a longer, or lesser
while.) Of which kind there be divers pieces to be seen in _Oxford_,
_London_, and elsewhere. And some of them being shewed to his Majesty, soon
after his happy restauration, they were broken in his presence, and found
to answer expectation. And others may be dayly seen, by any who is curious,
or desirous to see it.

_An Intimation of a Way, found in _Europe_ to make _China-dishes_._

Notice was lately given by an inquisitive _Parisian_ to a friend of his in
_London_, that by an Acquaintance he had been informed, that Signor
_Septalio_, a Canon in _Millan_, had the Secret of making as good
_Porcelane_ as is made in _China_ it self, and transparent; adding that he
had seen him make some.

This as it deserves, so it will be further inquired after, if God permit.

_An Account of an odd _Spring_ in _Westphalia_, together with an
Information touching _Salt-Springs_ and the straining of salt-water._

An observing Gentleman did lately write out of _Germany_, that in
_Westphalia_ in the Diocess of _Paderborn_, is a Spring, which looses it
self twice in 24 houres; coming always, after 6 houres, back again with a
great noise, and so forcibly, as {128} to drive 3 Mills not far from its
source. The Inhabitants call it the _Bolderborn_, as if you should say, the
_Boysterous Spring_.

_The same Person_, having mentioned the many _Salt-Springs_ in _Germany_,
as those at _Lunenburg_, at _Hall_ in _Saxony_, at _Saltzwedel_ in
_Brandenburger Mark_, in _Tyrol_, &c. observes, that no Salt-water, which
contains any Metal with it, can well be sodden to Salt in a Vessel of the
same Metal, which it self contains, except _Vitriol_ in Copper Vessels.

_He adds_, that, to separate Salt from Salt-water, without Fire, if you
take a Vessel of Wax, hollow within, and every where tight; and plunge it
into the Sea, or into other Salt-water, there will be made such a

behind: but, though this water have no saltish
