But whether the way there mentioned will succeed, or not, according to expectation: Sure it is that a Stone-cutter in _Oxford_, Mr. _Bird_, hath many years since found out a way of doing the same 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 separation, that the vessel shall be full of sweet water, the Salt staying behind: but, though this water have no saltish taste, yet, _he saith_, there will be found a Salt in the Essay, which is the Spirit of Salt, subtile enough with the water to penetrate the Wax. * * * * * _An Account of the Rise and Attempts, of a Way to conveigh Liquors immediately into the Mass of Blood._
