Although Mr. Cosh, at p. 248. of his admirable work on _The Method of Divine Government_, observes on the rapidity with which females descend to the depths of sin, the old apothegm, "Nemo repenti turpissimus fuit," recurs when thinking of Mary Queen of Scots, and leads me to ask the following question. Permit me to preface it with a remark. Mary is represented by all contemporary and subsequent writers to have been, from her earliest years to the death of Darnley, worthily beloved for her amiable qualities of heart and her superiority of intellect, and then to have fallen suddenly into an abyss of sin and wickedness, comprising domestic treason, murder, perjury, the subornation of perjurers, adultery, the conniving at divorce without adequate grounds, and all the other crimes connected with such proceedings; and then, after fifteen months of such a desperate course, to have risen to her former elevation, and have passed the remainder of her life with dignity, calmness, resignation, and in the habitual exercise of sincere piety, and to have met her death with a degree of heroism which has secured the admiration of posterity, and strengthened the doubts of her being guilty of the crimes imputed to her. The whole controversy, from Buchanan to Bell, is, I take for granted, known to your readers. Your publication is not the place suited to an examination of such mental operations, which are without a historical prototype, and without a known parallel. If any light can be thrown on any part of this subject, it becomes an act of historical justice, a work of Christian charity to Mary, and an illustration of the workings of the mind in a great emergency. The late Chevalier Bronsted, of whose learning and accuracy his archæological works bear record, and whose straightforward simplicity of mind was highly estimated by all who knew him, had read in manuscript the second part of the confession of Bothwell, made previous to his death. I think the manuscript was in the private cabinet of the King of Denmark. In that confession he owned to have _violated_ the person of Mary, and that she became enceinte; that she miscarried, and immediately took measures to rid herself of him. Concluding that event to have transpired, there seems to be some clue to her forwarding the discussion of her council, and acquiescing in their request to marry Bothwell. A young queen, surrounded by ruffians, barbarians, and selfish and unprincipled leaders of factions, placed in a situation in which every feeling of the woman was outraged, every sentiment lacerated, her honour, her station, her life in jeopardy, her memory liable to degradation and disgrace, in terror, having in such extremity no friend to whom she could apply for advice and succour, she may have been induced to adopt means for her safety which, if injudicious, were excusable. My request is, to learn if any of your correspondents have seen or are cognisant of this very curious and important document. ÆGROTUS.
