On the 12th of May, Mr. Henry Dundas brought down on behalf of the government, a second message from the King, importing that seditious practices had been carried on by certain societies in London, in correspondence with other societies; that they had lately been pursued with increasing activity and boldness, and had been avowedly directed to the assembling of a pretended National Convention, in contempt and defiance of the authority of Parliament, on principles subversive of the existing laws and the constitution, and tending to introduce that system of anarchy prevailing in France; that his Majesty had given orders for seizing the books and papers of those societies, which were to be laid before the House, to whom it was recommended to pursue measures necessary to counteract their pernicious tendency. A large collection of books and papers was, in consequence, brought down to the House; and, after an address had been voted, a resolution was agreed to, that those papers should be referred to a committee of secrecy. A few days after the King's message was delivered, the following persons were committed to the Tower on a charge of high treason: Mr. Thomas Hardy, a shoemaker in Piccadilly, who officiated as secretary to the London Corresponding Society; Mr. Daniel Adams, secretary to the Society for Constitutional Information; Mr. John Home Tooke; Mr. Stewart Kyd; Mr. Jeremiah Joyce, preceptor to Lord Mahon, eldest son of the Earl of Stanhope; and Mr. John Thelwall, who had for some time delivered lectures on political subjects in London.
