Mr. Parris informs us that the strange sicknesses existed in his family during several weeks before he or others had any suspicion that they might be of diabolical origin. Tituba dates their commencement on the evening of January 20, just six weeks before her examination. Therefore Mr. Parris's "several weeks" may have been five at least, during which he and his wife and their physician and friends probably studied symptoms, administered and watched the action of medicines, and cared for the children in every way, with as much freedom from delusion or bewildering excitement, as they could have done in any other equal portion of their lives. Such medical skill as then existed there, obviously had and used a very considerable period of time, not less than four or five weeks, in which to do its best, and yet was baffled. Its best was unavailing. We to-day perceive sufficient cause of its failure. It was contending against a special spirit infliction, the authors of which could either counteract, intensify, or nullify at their pleasure, the normal action of any common medicines or nursings. Parents, physician, and nurses no doubt witnessed from day to day such anomalous and changeful manifestations, sequent upon the administration of "physic," as confounded their judgments, and made them at last suspect "an evil hand." Tituba knew the cause of the illnesses, but probably lacked power to see and appreciate the continuous connection of that cause with the long series of its effects. Had she divulged her knowledge, what heed would have been given to the word of the ignorant slave? What beatings might she not well fear if she confessed to any dealings with invisible beings? No wonder that she kept her knowledge to herself, till fear of her master's cane influenced her to disclose the facts to the magistrates. Small as Tituba's mental capacities were, she had some unusual susceptibilities, which permitted, or rather obliged, her to possess more knowledge of the origin and progress, and also of the nature and of the active producer, of the distressing ailments and "amazing feats" in her master's family, than did master, mistress, physician, and magistrates combined. They saw--if it can be said that they saw at all--they saw only through thick, coarse, and blurred glasses, very dimly; while she, at times, clearly saw living actors face to face. From her we get the testimony of a witness who learned directly through her own senses what she stated; her testimony gives forth the ring of unflawed truth, and lifts a vail off from long-hidden mysteries.
