SOME time ago I believe I had the pleasure of telling you the story of an adventure which happened to a friend of mine by the name of Dennistoun* during his pursuit of objects of art for the museum at Cambridge.
He did not publish his experiences very widely upon his return to England; but they could not fail to become known to a good many of his friends: and among others to the gentleman who at that time presided over an art museum at another University.* It was to be expected that the story should make a considerable impression on the mind of a man whose vocation lay in lines similar to Dennistoun's, and that he should be eager to catch at any explanation of the matter which tended to make it seem improbable that he should ever be called upon to deal with so agitating an emergency. It was indeed somewhat consoling to him to reflect that he was not expected to acquire ancient MSS for his institution: that was the business of the Shelburnian Library.* The authorities of that might if they pleased ransack obscure comers of the Continent for such matters: he was glad to be obliged at the moment to confine his attention to enlarging the already unsurpassed collection of English topographical drawings and engravings possessed by his museum.* Yet, as it turned out, even a department so homely and familiar as this may have its dark corners, and to one of these Mr Williams was unexpectedly introduced.
