From this time the destruction of Overbury was resolved on between them. He was first committed to the Tower by an arbitrary mandate of James for refusing an embassage to Russia, next sequestered from all visitors, and finally attacked with poison, which, after several abortive attempts, was at length brought to effect. Meanwhile a divorce was sued for by the countess upon an allegation of impotence; and another female was said to have been substituted in her room, to be subjected to the inspection of a jury of matrons in proof of her virginity. After a lapse of two years the murder was brought to light, the inferior criminals, Mrs. Turner and the rest, convicted and executed, and Carr, now earl of Somerset, and his countess, found guilty, but received the royal pardon.--It is proper to add, in order to give a just idea of the state of human credulity at this period, that, Forman having died at the time that his services were deemed most necessary, one Gresham first, and then a third astrologer and enchanter were brought forward, to consummate the atrocious projects of the infamous countess. It is said that she and her second husband were ultimately so thoroughly alienated from each other, that they resided for years under the same roof, with the most careful precautions that they might not by any chance come into each other's presence. [215] LATEST IDEAS OF JAMES ON THE SUBJECT. It is worthy of remark however that king James lived to alter his mind extremely on the question of witchcraft. He was active in his observations on the subject; and we are told that "the frequency of forged possessions which were detected by him wrought such an alteration in his judgment, that he, receding from what he had written in his early life, grew first diffident of, and then flatly to deny, the working of witches and devils, as but falshoods and delusions."
