Before we look at his next proceeding, however, we must bring into view one or two facts essential to the understanding of the case. We have already observed on the universality of the belief in the ever-present agency of Satan in that region and that special season. In the woods the Red Men were his agents--living in and for his service and his worship. In the open country, Satan himself was seen, as a black horse, a black dog, as a tall, dark stranger, as a raven, a wolf, a cat, etc. Strange incidents happened there as everywhere--odd bodily affections and mental movements; and when devilish influences are watched for, they are sure to be seen. Everybody was prepared for manifestations of witchcraft from the first landing in the Bay; and there had been more and more cases, not only rumored, but brought under investigation, for some years before the final outbreak. This suggests the next consideration: that the generation concerned had no "alternative" explanation within their reach, when perplexed by unusual appearances or actions of body or mind. They believed themselves perfectly certain about the Devil and his doings; and his agency was the only solution of their difficulties, while it was a very complete one. They thought they knew that his method of working was by human agents, whom he had won over and bound to his service. They had all been brought up to believe this; and they never thought of doubting it. STATE OF PHYSIOLOGY. The very conception of science had then scarcely begun to be formed in the minds of the wisest men of the time; and if it had been, who was there to suggest that the handful of pulp contained in the human skull, and the soft string of marrow in the spine, and cobweb lines of nerves, apparently of no more account than the hairs of the head, could transmit thoughts, emotions, passions--all the scenery of the spiritual world! For two hundred years more there was no effectual recognition of anything of the sort. At the end of those two centuries anatomists themselves were slicing the brain like a turnip, to see what was inside it,--not dreaming of the leading facts of its structure, nor of the inconceivable delicacy of its organization. After half a century of knowledge of the main truth in regard to the brain, and nearly that period of study of its organization, by every established medical authority in the civilized world, we are still perplexed and baffled at every turn of the inquiry into the relations of body and mind. How, then, can we make sufficient allowance for the effects of ignorance in a community where theology was the main interest in life, where science was yet unborn, and where all the influences of the period concurred to produce and aggravate superstitions and bigotries which now seem scarcely credible?
