_Two_ of these letters are signed with the initial C.; and, on the similarity of the handwriting, it is assumed that the _three_ letters came from the same person. The writer of the _unsigned_ letter claims to have written many of the letters which had latterly appeared in the newspapers, and, amongst others, a letter signed Atticus, a copy of which he encloses. This is according to my recollection; but I will not say positively that he does not claim to be the writer of the _letters_ signed Atticus. The question, therefore, at present stands thus:--The connexion of these letters with the writer of Junius's letters is an inference or assumption, not a fact. It remains to be proved: and, for anything I know to the contrary, it may hereafter be proved by the editor of the _Grenville Papers_,--a diligent and careful man,--that the unknown writer of the unsigned letter is worthy of belief; that he was the same person who wrote the two letters signed C.; that Mr. Grenville's correspondent C. in 1768, was Woodfall's correspondent C. in 1769; and then, whether Mr. Grenville's Atticus was the same Atticus whose four letters were published as written by Junius, by Mr. _George_ Woodfall in the edition of 1812. Simple as this last question may appear, and naturally as most persons would come to a conclusion on the subject, I think it well to mention as a warning, that there were, as admitted in the _Public Advertiser_, two persons who about the same time wrote under that signature, and I think clear evidence of a third writer.
