In the next part, the authenticity of the letters is examined; and it seems to be proved, beyond contradiction, that the French letters, supposed to have been written by Mary, are translated from the Scotch copy, and, if originals, which it was so much the interest of such numbers to preserve, are wanting, it is much more likely that they never existed, than that they have been lost. The arguments used by Dr. Robertson, to prove the genuineness of the letters, are next examined. Robertson makes use, principally, of what he calls the _internal evidence_, which, amounting, at most, to conjecture, is opposed by conjecture equally probable. In examining the confession of Nicholas Hubert, or French Paris, this new apologist of Mary seems to gain ground upon her accuser. Paris is mentioned, in the letters, as the bearer of them to Bothwell; when the rest of Bothwell's servants were executed, clearing the queen in the last moment, Paris, instead of suffering his trial, with the rest, at Edinburgh, was conveyed to St. Andrew's, where Murray was absolute; put into a dungeon of Murray's citadel; and, two years after, condemned by Murray himself, nobody knew how. Several months after his death, a confession in his name, without the regular testifications, was sent to Cecil, at what exact time, nobody can tell. Of this confession, Leslie, bishop of Ross, openly denied the genuineness, in a book printed at London, and suppressed by Elizabeth; and another historian of that time declares, that Paris died without any confession; and the confession itself was never shown to Mary, or to Mary's commissioners. The author makes this reflection: "From the violent presumptions that arise from their carrying this poor ignorant stranger from Edinburgh, the ordinary seat of justice; their keeping him hid from all the world, in a remote dungeon, and not producing him, with their other evidences, so as he might have been publickly questioned; the positive and direct testimony of the author of Crawfurd's manuscript, then living, and on the spot at the time; with the publick affirmation of the bishop of Ross, at the time of Paris's death, that he had vindicated the queen with his dying breath; the behaviour of Murray, Morton, Buchanan, and even of Hay, the attester of this pretended confession, on that occasion; their close and reserved silence, at the time when they must have had this confession of Paris in their pocket; and their publishing every other circumstance that could tend to blacken the queen, and yet omitting this confession, the only direct evidence of her supposed guilt; all this duly and dispassionately considered, I think, one may safely conclude, that it was judged not fit to expose, so soon, to light this piece of evidence against the queen; which a cloud of witnesses, living, and present at Paris's execution, would, surely, have given clear testimony against, as a notorious imposture."
