I explored the wound; and first, marveling at the extraor. dinary nature of the case, I set about the examination of the heart. Taking it in one hand, and placing my finger on the wrist, I satisfied myself that it was indeed the heart which I grasped. I then brought him to the king, that he might behold and touch so extraordinary a thing, and that he might perceive, as I did, that, unless when we touched the outer skin, or when he saw our fingers in the cavity, this young gentleman knew not that we touched his heart !”
3. This absence of sensibility in the heart is not because it is not well endowed with nerves. It is well endowed, not with the nerves of ordinary sensation, but with those which are devoted to another purpose.
They are nerves of sympathy, which notify the condition of the heart to the seats of involuntary motion in the spinal marrow, and which also establish a connection with every part of the body, making the heart to be so easily affected by motion, by disease, and by every passing emotion in the mind. IV. THE REUNION AND HEALING OF SEVERED NERVES.
1. There are some wonderful facts in regard to the reunion and healing of severed nerves. It has been seen that if a nerve trunk be divided, all communication between the part which it supplies with branches and the brain is cut off. But the two cut ends of the trunk can grow together, and the communication can thus be more or less restored. This must appear to us passing wonderful when we consider that each nerve trunk is made up of a great number of separate fibres, each one of which goes from its origin in the nervous centre to its destination by itself. For these nerves to heal without causing confusion, it is essentially necessary that each little fibre should unite, at its cut end, with its corresponding end, and not with the end of some other fibre. For example, if the nerves distributed to the hand were cut, it would not do to have the fibres which go to the thumb unite with those which go to a finger.
2. The difficulty of accurate union would seem to us to be still further increased by the fact that, in the same bundle of 'nerve fibres, the different kinds, those of motion and those of sensation, are bound up together, and we know that it would not do for a nerve of motion to unite with a nerve of sensation. Yet we learn, by repeated experiments, that the most accurate union of severed nerves is often effected, each minute fibre, in whatever position it may be placed, apparently seeking out and uniting with its severed part, so that eventually the communication of impressions is as perfect as before.
3. But a still more wonderful fact is exhibited in the union of parts which did not originally belong together, as, for example, when a piece of skin is dissected from the forehead, and is twisted down so as to be made to grow upon the nose, to supply a deficiency there. Here entirely new relations are established between the nerves of the divided parts, and, as we should expect, there is confusion in the sensations. The patient at first, whenever the new part of the nose is touched, refers the sensation to the forehead. But this confusion of the sensations is after a while removed. And it is curious to observe, that while the old nervous connections are breaking up, and the new ones becoming established, there is an interval of partial, sometimes entire insensibility in the part. How these new relations can be established consistently with the known arrangement of the fibres in the nerve bundles is a mystery. Physiologists do not attempt to explain it; they merely attribute all such processes to what they call the “ Healing Power of Nature.” 1 Těxt'-ŪRES, different parts or layers, each ?

LES. VII.-INTEMPERANCE, THE PRIME MINISTER OF DEATH.
1. DEATH, the king of terrors, was determined to choose a prime minister;' and his pale courtiers, the ghastly3 train of diseases, were all summoned to attend, when each preferred his claim to the honor of this illustrious office.' Fever urged the numbers he destroyed; cold Palsy set forth his pretensions by shaking all
his limbs; and Dropsy, by his swelled, unwieldy carcass; Gout hobbled up, and alleged his great power in racking every joint; and Asthma's inability to speak was a strong though silent argument in favor of his claim. Colic and Rheumatism pleaded their violence; Plague his rapid progress in destruction; and Consumption, though slow, insisted that he was sure.
2. In the midst of this contention, the court was disturbed by the noise of music, dancing, feasting, and revelry, when immediately entered a lady, with a confident air and a flushed countenance, attended by a troop of cooks and bacchanals :6 her name was INTEMPERANCE. She waved her hand, and thus addressed the crowd of diseases: “Give way, ye sickly band of pretenders, nor dare to vie with my superior merits in the service of this great monarch. Am not I your parent? Do ye not derive the power of shortening human life almost wholly from me? Who, then, so fit as myself for this important office ?” The grisly monarch grinned a smile of approbation, placed her at his right band, and she immediately became his principal favorite and prime minister.-ANONY

LESSON X.-HOW THE MIND SPEAKS THROUGH THE
NERVES AND MUSCLES.
(Adapted chiefly from Sir Charles Bell.)
There is something that can not be told;
And thoughts—but the eye can unfold." 1. THERE is quite as much truth as poetry in the above fines—and, indeed, poets are often the most faithful interpreters of nature. Spoken and written language are not the only methods by which mind communicates with mind; and it will be found, on examination, that “the language that's mute," and that is read only in the moving play of the muscles,” forms the greater portion of the language of daily life.
2. Thoughts and feelings are expressed only by muscular motion as controlled by the nerves. Even the voice in speaking, and the hand in writing, merely translate the language of the muscles into conventional signs; but it is more especially of the mute language of the features, and of bodily motions, that we are now to speak. As we watch an animated speaker, we observe that not only are the muscles of the forehead, the eyebrows, the eyes, the cheeks, the nose, and the mouth in almost constant action, but the head is nodded or shaken, the shoulder is shrugged, the foot is stamped, the body variously inclined, and, above all, the hand executes a great variety of motions, and all to give force to the thoughts and feelings which the moûth utters.
3. Various muscles of the human features are also used to express thought or passion without any connection with the voice. So, also, the feelings or emotions which are attributed to the heart find expression here. Says the Son of Sirach, “The heart of a man changeth his countenance, whether for good or evil.” And so also Shakspeare, “I do believe thee; I saw his heart in his face.” Certain strong feelings of the mind produce a disturbed condition of the heart; thence the impulse is sent to the organs of breathing, which then give us, in this indirect way, the outward signs of the mental emotion. Sir Charles Bell says, “The man was wrong who found fault with Nature for not placing a window before the heart, in order to render visible human thoughts and intentions. There is, in truth, provision made in the countenance and outward bearing for such discoveries." These principles form a rational basis for the science of physiognomy.
