The Quarterly Journal of Science, Literature and the Arts, July-December, 1827 - Various

November 20th.

Cuttings of the fine new Portugal grape, of which fruit was exhibited on the 18th of September, were distributed to the members present. A few dahlia flowers still showed themselves, notwithstanding the unusual severity of some early frosts, and the room was crowded with chrysanthemums. The gloux morceau and beurré d’Aremberg pears were tasted, and found to retain the station which has been assigned to them at the head of all known varieties. [p428]
