Newark-upon-Trent, often chided us Physicians in York, for not writing upon it, and deservedly setting it upon the Wings of Fame." A more consistent form has been given to the error by Grainge, who in 1862 published a memoir of the Life of Sir William Slingsby, Discoverer of the first Spaw at Harrogate. Grainge, like Hargrove, had only access to Short's summary, but he sees the difficulty to which I have alluded, for he writes[14]:-- "From the uncertain expression of the Dr. 'about 50 years ago' the date of this discovery is generally fixed in the year 1576, though it is probably twenty years or more too early, as at that time Slingsby would only be fourteen years of age: and could not have travelled much in Germany or elsewhere: while the expression 'in his younger days' would infer that the discovery was not made until he had attained middle age at least." Grainge accordingly dates Captain (or Sir) William Slingsby's discovery to 1596 or later, the origin of the expression "near the close of the 16th Century" of the recognised history. In the first place Dr. Short is inaccurate in that Deane states it was discovered "55" years ago, and not "50." In the second place, the only authority whom Grainge could rely upon was Deane, either directly or indirectly, and Deane could not have made the discoverer to be a boy of nine years of age (not fourteen) for he must have known Sir William Slingsby, a contemporary. Finally, Grainge only consulted the summary of "Spadacrene Anglica" and not the actual work, and it is to be noted that Deane in Chapter 6 says the first discoverer "so far forth as I can learn." These words are not in the summary, but they show that Deane had given care to his work, and if Sir William Slingsby had been the discoverer, Deane could have obtained his information at first hand, and would have given Sir William Slingsby as his authority. Grainge was an eminent and careful historian, and he has written a number of valuable works. He had the acumen to see that Sir William Slingsby could not possibly have been the discoverer in 1571, and it is fairly certain that if he had had access to Deane's work, he would have rectified the error as regards Sir William, instead of questioning the accuracy of Deane's statement. Little has been added to the account of Mr. William Slingsby as given by Deane, but it has been shown at any-rate that the facts of his life fit in perfectly with that account.
