Since witnessing this exhibition, we have attended many others of pretty much the same character. We have more lately examined a clairvoyant case. The subject was a young man about twenty-five years old, of a retiring disposition, unassuming manners, and a temperament bordering on the phlegmatic. He was said by the mesmerizer to be a good example of the clairvoyant faculty. He was easily brought under the magnetic influence, and entered readily into conversation with the mesmerizer, who requested him to go to California and describe what he could there see. His descriptions of the country, climate, and mineral treasures, were merely, a rehearsal of the current newspaper articles of the day touching this all-absorbing subject. As these precious scenes were passing before his mind, his imagination began to give color and extension to his ideas, and the golden regions were rapidly stretched along the Rocky mountains, reaching far up the Oregon. Mountains glittering with gold, and valleys to their river bottoms, were shining with their precious stores. From this extensive field of observation, he was brought back by his mesmerizer to the contemplation of objects immediately before him, with the request to describe what he then saw. The scene had evidently changed. From barely rehearsing, in part, his own golden visions, probably the great sum of his daily thoughts, he was constrained to deal with things within the compass of his own observation, and it cost great effort to convince the audience that he possessed, without the use of ordinary sense, a tolerable knowledge of surrounding objects. But to give perfect satisfaction that he was in a completely abnormal state, a dentist extracted a large molar tooth without disturbing in the least the calmness of the patient. On awaking, he remembered nothing of these circumstances.

The question now arises, did the subject see when he described surrounding objects, or was it a reflection of the mind of the mesmeriser? See, he certainly could not, because his eyes were closed, and the pupils were permanently dilated; but he assuredly did by some means perceive the objects, otherwise he could not have described them. Whether in this particular it was a reflection of the mind of the mesmerizer, or whether it was identical with an ordinary occurrence of somnambulic sleep, is difficult to determine. His descriptions of California were undoubtedly drawn from his own mind.

During this exhibition, his conductor again required him to change the scene of his observations, and it was thence transferred to the spirit land. The first object he there saw, was a near relative of the magnetizer who had been dead some years, but whose memory, from peculiar circumstances, was strongly impressed upon his mind. Of this person he gave an apt description. He also saw his own mother, on having his attention so directed, who also had been dead a long time; of her too he gave a good description. In the former instance, he presented a counterpart of the mind of the manipulist, but in the latter he must have drawn upon his own memory, because his mother was unknown to the lecturer.. The description of the deceased relative of the mesmerizer in the one case, most fully confirms the opinion that he simply reflected the mental operations of the mesmerizer; and the description of his own mother, an entire stranger to the lecturer, proves that he drew upon his own memory alone; while his imagination arranged the whole so as to appear a present reality. Throughout the exhibition, the power of the mesmerizer in directing the attention of this patient to particular subjects, but without the power of controlling him relative to them, was entirely conclusive.

Now to say, that, because the statements of the clairvoyant are correct in regard to circumstances with which we are acquainted, we are bound to believe them equally so in regard to such as are beyond the reach of human knowledge, is unphilosophical; because we should attempt to apply analogical reasoning to that branch of philosophy which is itself the source of all reason. Analogy is merely the means whereby the reason assists itself in determining properties subordinate to its own powers.

From among the many experiments showing the influence of animal magnetism on the sensitive apparatus, we will copy a surgical case which occurred in hospital practice. "James Wombell, 42, a laboring man, had suffered for a period of about five years with a painful affection of the left knee joint. He was admitted into the hospital at Wellow, in Nottinghamshire, and it wag decided that amputation should take place above the knee joint, and it was accordingly done while the patient was under the influence of mesmeric sleep! On the 1st of October this wonderful operation was thus performed, as given in the words of the mesmerizer, one Mr. W. Topham, a lawyer of the Middle Temple, London: I again mesmerized him in four minutes. In a quarter of an hour I told Mr. W. Squire Wood (the operator), that he might commence. I then brought two fingers of each hand gently in contact with Wombell's closed eyelids, and there kept them still further to deepen the sleep. Mr. Wood, after one earnest look at the man, slowly plunged his knife into the centre of the outer side of the thigh, directly to the bone; then made a clear incision round the bone to the opposite point, on the outer side of the thigh. The stillness at this moment was something awful. The calm respiration of the sleeping man alone was heard, for all others seemed suspended. In making the second incision the position of the leg was found to be more inconvenient than it had appeared, and the operator could not proceed with his former facility.

"Soon after the second incision, a moaning was heard from the patient, which continued at intervals until the conclusion. It gave me the idea of a troubled dream, for his sleep continued as sound as ever. The placid look of his countenance was never changed for an instant: his whole frame rested, uncontrolled, in perfect stillness and repose: not a muscle or nerve was seen to twitch. To the end of the operation, including the sawing of the bone, securing the arteries, and applying the bandages - occupying, a period of more than twenty minutes - he lay like a statue. With strong sal volatile and water, he gradually and calmly awoke, and when asked to describe what he had felt, thus replied: 'I never knew anything more
