To William Cookworthy, of Kingsbridge, and Lord Camelford we owe the production of porcelain at Plymouth. They worked together, and took out a patent in 1768. For the manufacture, Cookworthy discovered kaolin and pentuse in Cornwall, both natural substances, requisite for the production of hard paste; the former to supply an opaque body, and the latter a perfectly transparent substance, commonly called "moonstone," or "chinastone," the two being blended together. In the first patent taken out in this country in 1768, the porcelain was described as made of moonstone, or granite and china clay, the latter giving infusibility and whiteness, Henry Bone, the enameller, and M. Soqui, a painter from Sèvres, being the decorators of the Coxside manufactory at Plymouth. After a lapse of a few years, the interest of the latter was sold, and the patent rights transferred to Mr. Champion, of Bristol, in 1774. The mark of the original Plymouth porcelain was the alchemic symbol for tin, sometimes, but rarely, incised in the clay, in blue under the glaze, or in gold or red upon it; but many pieces have no mark at all. A great similarity appeared between the work executed at Plymouth and that in Bow, which may be accounted for by the fact that Cookworthy employed workmen procured from the last-named factory. Some £3,000 were expended in perfecting the discovery of how to bring the porcelain to perfection. [Illustration: PLYMOUTH MARK.] (_To be continued._) NEIGHBOURS. One of the penalties of the "civilisation" that drives so many people to live in cities, is that they must have neighbours, good, bad or indifferent, in close proximity. There are still some houses in cities standing alone and surrounded by garden or shrubbery, but the majority of dwellers in towns must, by force of circumstances, have people next door. These cannot be altogether ignored (though it is wonderful how the habit grows of minding one's own business), and we have to bear with their faults and their failings. A great help in this direction is to remind ourselves that we are also somebody's neighbour, and, no doubt, they have faults to find with us.
