whence wee guess, that it is mixed of them both, meeting there together: to confirm which, we have mixed equal quantities, of those two, with an addition of a litle common well-water, and have found that they, being stirred together and permitted to setle, made just a water of the same colour and tast of this third stream. * * * * * _Of some other not-common Springs at _Basel_ and in _Alsatia_._ A Curious Person writes from those Places in manner following; {135} At _Basel_ the Spring, running in the _Gerbergasse_ (or _Tanners-street_) from St. _Leonard's_ Hill, is of a Blewish colour, and somewhat troubled, holding Copper, Bitumen, and Antimony, about 3 parts of the first, one of the second, and two of the last, as has been examined by skilful Persons. Our Tanners do water their Skins in it; and being a well-tasted and wholesome Water, it is both much drunk, and used to Bath in. It mingles with another Spring water, call'd the _Birsick_, and with it, between the _Salt-tower_ and the _Rhine-gate_ runs into the _Rhine_. In the same Town (which abounds with Spring-waters) there are two, among the rest, called _Bandulph's-well_, and _Brun Zum Brunnen_, that are more observable then the other; the former of them having a _Camphory_ and drying Quality, and used against Hydropical Distempers; the latter containing some Sulphur, Saltpeter and Gold, and being an excellent Water to drink, much used in the principal Tavern of the City, where the chief of the Town do resort, and near which it runs.
