So few examples of glass vessels of this period which have been painted in enamel have come down to us that it has been questioned whether that art was then practised; but several specimens have been described which can leave no doubt on the point; decisive examples are afforded by two cups found at Vaspelev, in Denmark, engravings of which are published in the Annaler for Nordisk Oldkyndeghed for 1861, p. 305.
One of the most noteworthy Scandinavian periodicals has been the Nordisk Universitets Tidsskrift (1854-1864), a bond of union between the universities of Christiania, Upsala, Lund and Copenhagen.
