As in these extreme moments of life, so in the hour of extreme danger, when an awful fate is impending, and the world and our sacred friendships are about to be lost to us, a vision of our absent friends will pass before us with all the light of reality. We read in the writings of Dr. Conolly of a person who, in danger of being swamped on the Eddystone rock, saw the phantoms of his family passing distinctly before him; and these are the words of the English Opium-Eater:—“I was once told by a near relative of mine that, having in her childhood fallen into a river, and being on the very verge of death but for the critical assistance which reached her, she saw in a _moment_ her whole life in its minutest incidents arrayed before her simultaneously, as in a mirror, and she had a faculty developed as suddenly for comprehending the whole and every part.” Now, although the coming on of death is often attended by that slight delirium indicated by the babbling of green fields, and the playing with flowers, and the picking of the bedclothes, and the smiling on the fingers’ ends, yet in others some oppressive or morbid _cause of insanity_ may be removed by the moribund condition. In the words of Aretæus,—“the system has thrown off many of its impurities, and the soul, left naked, was free to exercise such energies as it still possessed.” I will glance in illustration at these interesting cases:—from Zimmerman, of an insane woman of Zurich, who, “a few hours before her death, became perfectly sensible and wonderfully eloquent;”—from Dr. Perceval, of a female idiot, who, as she was dying of consumption, evinced the highest powers of intellect;—from Dr. Marshall, of the maniac, who became completely rational some hours previous to his dissolution;—and from Dr. Hancock, of the Quaker, who, from the condition of a drivelling idiot, became shortly before his death so completely rational, as to call his family together, and, as his spirit was passing from him, bestow on them with pathetic solemnity his last benediction. Thus your impressive records are clearly explained by pathology; and, perhaps unconscious of this, Mrs. Opie has a fine illustration in her “Father and Daughter:”—the mind of the maniac parent being illumined before his death by a beam of reason. But in the languid brain of an idiot excitement may even produce rationality. Samuel Tuke tells us of a domestic servant, who lapsed into a state of complete idiocy. Some time after, she fell into typhus fever, and as this progressed, there was a real development of mental power. At that stage when delirium lighted up the minds of others, _she_ was rational, because the excitement merely brought up the nervous energy to its proper point. As the fever abated, however, she sunk into her idiot apathy, and thus continued until she died. It was but the _transient gleam_ of reason. PHANTASY FROM CEREBRAL CONGESTION.—OPIUM.
