Before watches became common, seals were sometimes attached to the arms, like bracelets. In _Mercurius Rusticus_, No. 30 (for 19/20 July, 1660), an advertisement appears for "a gold seal, being a coat of arms, cut in a piece of gold, in the form of a lozenge, fastened to a black ribband to tye about the wrist." In the _Visitation of Essex, 1634_ [Harleian Society, p. 455], appears the following certificate:--"This coate is certiffied by Thomas Scott to bee by him seen on a seale some 40 years since, and to be the seale of armes of Thomas Moore Esq. father of the said Hunting Moore, and that Robert Scott his father did weare the same about his neck in a scarffe about xx yeares--in witnes whearof I have sett to my hand. Tho. Scott." [Robert Scott had married Anne, daughter of Richard Hunting and relict of Thomas Moore, of Orsett, co. Essex.] This seal was, of course, a ring. Watches, which naturally suggest small attached seals, were, however, in pretty general use in Queen Elizabeth's reign. In Shakespeare's _Twelfth Night_, Malvolio says:--"I frown the while, and perchance _wind up my watch_, or play with some rich jewel." A watch was found upon Guy Fawkes, 3 James I. (1605/6), which he and Percy had bought the day before, "to try conclusions for the long and short burning of the powder."--Stow's _Chronicle_, p. 878, and introduction to Mr. Reuben Burrow's _Almanac_ for 1778. LINES FOR TINCTURES. The first English examples of seals with lines in the engraving, to indicate the tinctures, are said to be on some of those attached to the death warrant of Charles I., 1648-9 [Planché's _Pursuivant of Arms_]. Now, as this system was unquestionably first devised by Father Silvester de Petra Sancta--whose two books, _L'Armorial ou la Science du Blason_, 4to, and _Soumaire Armorial_, 4to, were both published in Paris 1638--it seems curious that within ten years we should find such conventional lines in use in England; and it follows, also, that such of these seals as were so treated in 1648 must all have been recently cut! A diagram, showing the colours so indicated, is given by Sir Edward Bysse in his edition of Nicholas Upton's work, _De Usu Militari_, published in 1654. The earlier works on heraldry, which I have been able to consult, have the illustrations in somewhat rough wood blocks--it would have been difficult and expensive at that time to have got finer work in wood; but we must remember that Sylvanus Morgan, in his _Armilogia_, published 1666, refers to Silvester de Petra Sancta's Epistles, and elaborately describes--as if they were something quite startling and new--why the several conventional lines were selected. John Gibbon, in his _Introductio ad Latinam Blazoniam_, published London 1682, p. 152, says, "for the distinction of colours in arms [which was devised by the Rev. Father S. de Petra Sancta]," and he (Gibbon) frames some Latin verses for the better remembering
