In this pamphlet L'Estrange gave the titles of most of the pamphlets to which he objected, with brief extracts from them, and the names of the printers and publishers, amongst whom were Thomas Brewster, Giles Calvert, Simon Dover, and one other, whose name is not mentioned, but who is referred to as holding a highly profitable office. The reference may be to Thomas Newcomb. At pages 26 and 27 L'Estrange notices the petition of certain of the printers to be incorporated as a separate body. He says 'that it were a hard matter to pick out twenty master printers, who are both free of the trade, of ability to manage it, and of integrity to be entrusted with it, most of the honester sort being impoverished by the late times, and the great business of the press being engross'd by Oliver's creatures.' He admits that the Company of Stationers and Booksellers are largely responsible for the great increase of presses, being anxious to have their books printed as cheaply as possible, but thinks that there would be as much abuse of power among incorporated printers as among the Company of Stationers. The Act of 1662, which was mainly based on L'Estrange's report, was in a large measure a re-enactment of the Star Chamber decree of 1637. The number of printers in London was limited to twenty, the type-founders to four, and the other clauses of the earlier decree were reinforced, but with one notable concession. Hitherto printing outside London had been restricted to the two Universities, but in the new Act the city of York was expressly mentioned as a place where printing might be carried on. This new Act was enforced for a time with greater severity than the old one, and under it, for the first time in English history, a printer suffered the penalty of death for the liberty of the press. The story of the trial and condemnation of John Twyn is told in vol. 6 of Cobbett's _State Trials_, and was also published in pamphlet form with the title, _An exact narrative of the Tryal and condemnation of John Twyn, for Printing and Dispersing of a Treasonable Book, With the Tryals of Thomas Brewster, bookseller, Simon Dover, printer, Nathan Brooks, bookseller ... in the Old Bayly, London, the 20th and 22nd February 166-3/4_.
