[959] A plate of this kind was called παράγραφος, also τροχαλὸς, γυρὸς, κυκλοτερὴς, which last appellation denotes the form. The Romans, at least those of later times, named this lead præductal. The ruler by which the lines were drawn was called κανὼν and κανονίς. Thus the ruled sheet which Suffenus filled with wretched verses is styled by Catullus membrana directa plumbo. Pollux has παραγράφειν τῇ παραγραφίδι. See Salmasius ad Solinum, p. 644, where some passages, in which these leaden plates are described, are quoted from the Anthologia.

[963] This, however, is not exactly the case. With ink somewhat thick one may indeed write on a piece of paper which has been rubbed over with black lead.
[964] [This was formerly the case, but for a considerable number of years past the mine has been constantly open. The whole of the produce is sent up to London (Essex Street, Strand), where it is disposed of by public auction, held once a month.]
[965] In the Cumberland dialect, killow or collow, as well as wad, means black. Therefore when the manganese earth, which is found chiefly at Elton not far from Winster, and when burnt is employed as an oil-colour, but particularly for daubing over ships, is called black wad, that expression signifies as much as black black.
