This case involves a question of fact of great delicacy and difficulty. The testimony is voluminous and contradictory. We feel indisposed to try such a question, and the more so, as in such inquiries, depending on matters of opinion, it is important to see the witnesses, in order to form a judgment of their competency and skill, to form an accurate opinion upon the question of sanity. An issue must be made up, and sent to a jury.
