These glasses have usually air-drawn or knopped stems and funnel-shaped bowls. These Jacobite glasses are among the luckiest “finds” of the collector of Old English glass, and it is needless to say that the greatest care is essential in purchasing anything which purports to be a genuine specimen. “Fiat” glasses, especially those bearing the portrait of the Pretender, are imitated in considerable numbers and generally disposed of through the shops of small country dealers, pawnbrokers, etc.; but I have seen specimens, even in galleries and large shops in London, which were flagrant frauds, a fact which should have been perfectly patent to the vendors. So _caveat emptor_. Frequently the ordinary tests for the antiquity of the glass are useless, since the piece is itself genuine old glass of the proper period and [Illustration: FIG. 19--JACOBITE GLASSES. (From the Rees Collection, by permission of the Connoisseur.)] only the engraving modern, and this is given a spurious appearance of age by rubbing down with sand and earth, and by allowing the lines of the pattern to become filled with dust and dirt. A test that may be found useful is to hold the piece in a strong light, when some part of the engraved portion may be found untouched by the “treatment,” and bearing in its clearness and sharpness of line convincing evidence of its recent origin. Of the Jacobite glasses, those dedicated to the Old Pretender are entirely beyond the hopes of the ordinary collector. A few exist in old country houses dotted up and down the country and in various museums. One in the British Museum bears the mottoes “_Cognoscunt me mei_” and “_Premium Virtutis_.” Young Pretender glasses are naturally much more numerous, and it is probable that specimens may still be found in out-of-the-way places. Special finds of Jacobite glasses are occasionally made, a whole set being discovered in some unexpected hiding-place. One such set is the famous Oxburgh Hall find, now to be seen and admired in the Victoria and Albert Museum. Eleven Jacobite glasses in all were discovered, eight of them being “Fiat” glasses. Four of them, of a larger size, bear the Prince of Wales’ feathers on the upper surface of the foot. One is the glass inscribed to Sir Watkin Wynn, previously mentioned, and one is of special significance, in that it bears in addition to a portrait of the Young Pretender an inscription, unique in the history of Jacobite glass: “Charles ye Great, ye Brave, the Just and Good Britania’s Prince ye noblest of her Bld. Thy Glorious Feats ye World may Proᵐ Britania’s Glory and Britaine Shame.”
