"She had these periodic spells of preaching for five or six years, every two weeks regularly, never having missed but two or three times. The case having attracted much attention, Dr. B. was induced to visit the subject of it during one of her attacks, and gave the following account of what he observed. He arrived at nine o'clock A.M., and found Mrs. B. sitting in an arm-chair, suffering all the agony of a severe attack of facial neuralgia of the right side, though somewhat different from most cases of that disease. There was no twitching of the muscles, great turgescence of the vessels of the face and neck, muscles of the neck very rigid, eyes very red, excessive intolerance of light, so much so that she could scarcely bear to elevate the eyelids.

"She says she feels an almost insupportable weight, like an incubus, upon her head; there is an abundant secretion of saliva, which is altogether from the right side of the mouth. I talked with her about an hour, or as long as she was capable of talking. I found her a very intelligent woman; she wished to know if there was nothing that would relieve her. I asked her if she had undergone any medical treatment. She said she had; that several eminent physicians had given her medicine. She had been cupped, her head shaved and blistered, ointment of veratria applied to the course of the nerve, and all the noted antiperiodics given in succession without the least benefit. She thought that under the tonic treatment she had got worse.

"She continued to get worse and worse from the time I went into the room until about eleven o'clock, when her eyes closed, and she became perfectly insensible to external impressions. In this situation she Commenced talking.

"She was placed in the sitting posture, in a large room where a great number of strangers had collected. When she first commenced talking, she appeared to be choked with a frothy saliva, but she soon cleared her throat, and preached for two hours and ten minutes, in a clear and distinct voice - sufficiently loud to be heard a hundred yards. Sometimes her appeals would be the most pathetic and eloquent I ever heard. The first warning you have that she is about to conclude, is the free spitting up of this frothy saliva. As soon as that appears, she falters and falls over. She continues insensible for fifteen or twenty minutes, all the time spitting up this saliva, when she awakes by yawning like a person who had been asleep, and looks about with a vacant stare. She soon, however, regains her senses, and looks like another person, and knows nothing of what has transpired.

"The most remarkable circumstance connected with this case is, that she can neither see, hear, nor feel during all the time she is preaching. She is not disturbed by any noise that may be made, and if pricked by any sharp instrument, does not flinch, and her eyes are closed during the whole time."

Dr. Berkley relates this as a case of double consciousness, but we do not consider it as such, because there was no connexion between the pathological condition and its preceding homogeneous attacks, although the patient did exhibit a periodic abnormal state. For an individual to possess double consciousness, there must be a corresponding identity in each state of the same kind. The mental peculiarities of the abnormal states must be in as perfect harmony with each other as those of the natural: and the two states must not only present a character totally distinct, but each must be connected with the preceding states of the same kind, so that either condition has a separate and distinct consciousness connecting its alternate fragments into a perfect whole. In fact, the subject, to be doubly conscious, must present, alternately, the mental characteristics of separate and distinct individuals. The case, however, is important, in that it furnishes additional evidence of the dependence of memory upon sensational integrity. In the further consideration of the subject in its connexion with memory in our conclusion, we shall present a case exhibiting the peculiar features of double consciousness.

The mind in somnambulism is always conscious. It may or it may not perceive external relation, but the physical phenomena show conclusively that the mental being is at work. It will appear, when examining, in our concluding remarks, the memorial power, that the mind may be cognisant of surrounding circumstances, and yet retain no remembrance of them, because sensation - the foundation upon which memory rests - is wanting.
