From Chapter 3:
The tobacco-tongs were more properly called ember-or brand-tongs. They sometimes had a tobacco-stopper riveted in near the axis of the tongs, and thus could be easily distinguished from other kinds of tongs. An example in the Guildhall Museum, made of brass, and probably of late seventeenth-century date, has the end of one of the handles formed into a stopper. In the same collection there are several pairs of ember-tongs with handles or jaws decorated. In one or two a handle terminates in a hook, by which they could be hung up when not required for use. In that delightful book of pictures and gossip concerning old household and farming gear, and old-fashioned domestic plenishings of many kinds, called "Old West Surrey," Miss Jekyll figures two pairs of old ember-or brand-tongs. One of these quite deserves the praise which she bestows upon it. "Its lines," says Miss Jekyll, "fill one with the satisfaction caused by a thing that is exactly right, and with admiration for the art and skill of a true artist." These homely tongs are fashioned with a fine eye for symmetry, and, indeed, for beauty of design and perfect fitness for the intended purpose. The ends which were to pick up the coal are shaped like two little hands, while "the edges have slight mouldings and even a low bead enrichment. The circular flat on the side away from the projecting stopper has two tiny engraved pictures; on one side of the joint a bottle and tall wine-glass, on the other a pair of long clay pipes crossed, and a bowl of tobacco shown in section." This beautiful little implement bears the engraved name of its Surrey maker, and the date 1795.

From Chapter 6:
But so early as 1655 there is a sign of change of custom—a change, that is, in the direction of restricting and limiting the hitherto unbounded freedom granted to the use of tobacco. The London Society of Apothecaries on August 15, 1655, held a meeting for the election of a Master and an Upper Warden; and from the minutes of this meeting we learn that by general consent it was forbidden henceforward to smoke in the Court Room while dining or sitting, under penalty of half a crown.
