The Mayors of various towns in the pottery districts of England have petitioned the Chancellor of the Exchequer that this beautiful and rare collection of specimens of the ceramic art may be purchased for the use of the nation, as they believe that such a museum would tend to improve the decorative manufactures of the country. A union of the art-trades has been formed in London to bring the matter before the House of Commons immediately on its re-assembling. The collection was formed by a French gentleman, M. Soulages, and it is now for sale by his representatives.
