THE LONDON-SPAW.  
Advertisement, August 1685.  
THIS Paper is to Inform any person of what Condition Quality or Sex soever, That at and in the now dwelling House of John Halhed Vintner and Victualler, in the Parish of St. James Clarken Well, London; in the way going up to Islington, at the Sign of the Fountain, is a Medicinal Water which( upon the mature Consideration, many trials, and serious Deliberation of that most Famous, eminently Learned, and long experienced Philosopher, chemist and Physician, the honourable Robert boil Esq;) was adjudged and openly declared to be the strongest and very best of these late found-out Medicinal Iron Waters; Though 'tis acknowledged the others near this place are not without their Commendation,( which they justly deserve) but this is equivalent, if not better, in Virtue Goodness and Operation to that of Tunbridge,( so mightily cried up) or any other Iron water yet known; and was therefore upon the Fourteenth of July last past, by him deservedly nominated and called The LONDON-SPAW, before an eminent, knowing and more than ordinary ingenions Apothecary, whose Curiosity drew him thither, and was then and there present and heard it, besides the said John Halhed, and other sufficient men: And it is very observable, That this Water alone had first that Name given to it; and therefore the Owner desires all persons to take particular Notice of it, and to take it into their serious consideration: especially all those that drink of Medicinal Waters, seeing a much less quantity of this water works the same effect as a greater quantity of others does do. And if men will not believe him, who for his excelling in experimental knowledge, being one of the Principals of the Royal Society, and the glory of our English Nation, 'tis hard to say, whom they will believe. Yet this is not printed to persuade Gentlemen, Ladies or any other persons whatever to depend on his judgement only, but it being so very nere the City, and so very easyo make trial of; It is therefore desired by the Owner, that they will be pleased to call at his House, and not only see but taste the Waters, and be their own Judges: And also he wishes that the Greatness of his Accommodation were suitable to the Goodness of his Water, for the sake of those Persons of Quality he invites to come thither; notwithstanding he is not without convenient Apartments and Walks for both Sexes, but more especially for the Female Sex. And this may serve further to inform all persons. That divers other able Physicians of the college of LONDON, did readily concur with the above mentioned the honourable, and Learned boil, in the same judgement to a tittle; some of which ought to be consulted and advised with; by all those persons that intend to drink them, in order to a due preparation of their Bodies before their taking, and their methodical ways in taking of them, as to the time, when and how long, as well as to what Quantity, for the more speedy and more effectual way of curing of those many Distempers and Diseases, they are by being regularly and advisedly taken, capable to cure, too tedious to be here inserted; of all which by able physicians you will be fully and thoroughly informed. I shall conclude all with my Hearty return of all imaginable Thanks to those worthy deserving and public Spirited Physicians, who first made the discovery of this excellent Medicinal Water for Me; and to whom I acknowledge myself ever obliged.
