"was discovered by Capt. William Slingsby, about the year 1571. This Gentleman, in the early part of his life, had travelled in Germany, where he made himself acquainted with the Spaws of that country. He lived sometime at Grange House, near the Old Spaw, from whence he removed to Bilton Park, where he spent the remainder of his days. He made severall trials of this water, and finding it like the German, he walled it about, and paved it at the bottom, leaving a small opening for the free access of the water. Its current is always near the same, and is about the quantity of the Sauvenir, to which Mr. Slingsby thought it preferable." From this quotation it is clearly apparent that Hargrove erroneously inferred that Mr. Slingsby and Capt. Slingsby were the one and the same person instead of being uncle and nephew. In the 3rd edition of the "History of Knaresborough," published in 1782, the reference to Mr. Slingsby is omitted and from that edition onwards, Captain Slingsby appears as the discoverer of the Tuewhit Well in 1571, a discovery clearly inconsistent with the fact that he was born in the year 1562. The source of Hargrove's information in the above quotation is, without doubt, the summary of "Spadacrene Anglica," published by Dr. Short in 1734 in his History of Mineral waters.[13] The summary by Short of Chapter 6 of "Spadacrene Anglica" is as follows:-- "This fifth Spaw is a Mile and half from Knaresburgh, up a very gentle ascent, near Harrigate, has much the same Situation as the foresaid Spaws in Germany. It was discovered first about fifty years ago, by one Mr. William Slingsby, who had travelled in Germany in his younger Years, seen, and been acquainted with theirs; and as he was of an ancient Family near the place, so he had fine Parts and was a capable Judge. He lived some time at a Grange-House near it; then removed to Bilton-Park, where he spent the rest of his Days. He, using this Water yearly, found it exactly like the German Spaw. He made several Tryals of it, then walled it about, and paved it in the bottom with two large Stone-flags, with a Hole in their sides for the free Access of the Water, which springs up only at the bottom, through a Chink or Cranny left on purpose. Its current is always near the same, and is about the quantity of the Sauvenir, to which Mr. Slingsby thought it preferable being more brisk and lively, fuller of Mineral Spirits, of speedier Operation; he found much benefit by it. Dr. Tim. Bright, about thirty years ago, first gave it the name of the English Spaw: Having spent some time at those in Germany, he was Judge of both; and had so good an Opinion of ours, that he sent many Patients hither yearly, and every Summer drank the Waters himself.
