metallic moulds, an art which has been considered of modern invention. English glass-makers considered the patent pillar glass a modern invention until a Roman vase was found (it is now to be seen in the Polytechnic Institution in London), being a complete specimen of pillar moulding. Pillat states in his work that he had seen an ancient drinking vessel of a Medrecan form, on a foot of considerable substance, nearly entire, and procured from Rome, which had the appearance of having been blown in an open-and-shut mould, the rim being afterwards cut off and polished. This is high authority, and, with other evidences that might be cited, goes far to prove that the ancients used moulds for pressing, and also for blowing moulded articles, similar to those now in use.     Pompeian window-glass, of which panes have been discovered as large as twenty by twenty-eight inches, has proved, on examination, to have been cast in a manner similar to that now followed in making plate-glass, except that it was not rolled flat, as now, by metal cylinders, but pressed out with a wooden mallet, so that its thickness is not uniform.     A glass has been discovered at Pompeii, about the size of a crown piece, with a convexity, which
