The following remarkable account of this scientific monster is given in an “Historical Account of the Warrington Academy, an institution in Lancashire,” published in the _Monthly Repository_, by the Rev. W. Turner, of Wakefield. “After the departure of DR. REINHOLD FORSTER, various unsuccessful attempts were made to engage a foreigner in the capacity of teacher of the modern languages—a M. FANTIN LA TOUR, a M. LE MAITRE, _alias_ MARA, and a MR. LEWIS GUERY; but none of them continued for any length of time.... There is great reason to believe that LE MAITRE, _alias_ MARA, was the infamous MARAT.... It is known that he was in England about this time [1774], and published in London “A Philosophical Essay on the connection between the Body and the Soul of Man,” and, somewhere in the country, had a principal hand in printing, in quarto, a work of considerable ability, but of a seditious tendency, entitled—‘_The Chains of Slavery: a work wherein the clandestine and villainous Attempts of Princes to ruin Liberty are pointed out, and the dreadful Scenes of Despotism disclosed, etc.; London, sold by J. Almon.... T. Payne, and Richardson and Urquhart, 1774._’ MARA, as his name is spelt in the Minutes of the Academy, very soon left Warrington, whence he went to Oxford, robbed the Ashmolean Museum, escaped to Ireland, was apprehended in Dublin, tried and convicted in Oxford, under the name of LE MAITRE, and sentenced to the hulks at Woolwich. Here one of his old pupils at Warrington, a native of Bristol, saw him. He was afterwards a Bookseller in Bristol, and failed; was confined in the gaol of that city, but released by the Society there for the relief of prisoners confined for small sums. One of that society, who had previously relieved him in Bristol Gaol, afterwards saw him in the National Assembly in Paris in 1792.”
