In _Alsatia_ in the Valley, called _Leberthal_, near _Geesbach_ (an ancient Mine-work) there runs out of a _Cavern_ a foul, fattish, oily Liquor, which, though the Country-men of that place employ to the vile use of greasing their Wheels, instead of ordinary Wheel-grease; yet doth it afford an excellent Balsom, by taking a quantity of it, and putting it in an Earthen Pot well luted, that no steam may exhale; and then with a gentle Fire at first, but a stronger afterwards, boyling it for three hours together; in which space it will boyl in a fourth part, and an Earthen Matter, like Pitch, will settle it self at the bottom: but on the top thereof, when cold, there will swim a fatty Substance, like Lyne-Oyl, limped and somewhat yellowish, which is to be decanted from the thick Sediment, and then gently distilled in an Alembick in _Arena_, by which means, there will come over two differing Liquors, one Phlegmatick, the other Oily, {136} which latter swimming on the Phlegm, is to be severed from it. The Phlegm is used as an excellent Resister and Curer of all the Putrefactions of the Lungs and Liver, and it heals all foul Wounds and Ulcers. The Oily part, being diluted with double its quantity of distilled Vineger, and brought three times over the Helm, yields a rare Balsom, against all inward and outward Corruptions, stinking Ulcers, hereditary Scurfs and Scabs: 'Tis also much used against Apoplexies, Palsies, Consumptions, Giddinesses, and Head-aches. Inwardly they take it with Succory-water against all corruptions of the Lungs. It is a kind of _Petroleum_, and contains no other Mineral Juice, but that of _Sulphur_, which seems to be thus distilled by _Nature_ under ground; the distillation of an Oyl out of _Sulphur_ by Art, being not so easie to perform. * * * * * _Of the richest _Salt-Springs_ in _Germany_._ An Account having been desired of those two chief _Salt-Springs_ in _Germany_, at _Hall_ and _Lunenburg_, it was lately transmitted thus: The _Salt-Springs_ at _Hall_ in _Saxony_ are four, called _Gutiaar_, the _Dutch-Spring_, the _Mettritz_, and the _Hackel-dorn_; whereof the three first hold near the same proportion of Salt; the last hold less, but yields the purest Salt. The three first hold about seven parts of Salt, three of Marcasit, and fourteen of water: They are, besides their Oeconomical use, employed Medicinally to Bath in, and to draw a Spirit out of it, exhibited with good success against Venom, and the putrefaction of the Lungs, Liver, Reins, and the Spleen. The _Salt Water_ at _Lunenburgh_, being more greenish then white, and not very transparent, is about the same nature and hold with that of _Hall_. It hath a mixture of Lead with it, whence also it will not be sod in Leaden Pans, and if it held no Lead at all, it would not be so good, that Metal being judged to _purifie_ the Water: whence also the Salt of {137} _Lunenburg_ is preferred before all others, that are made of Salt Springs.
