6. In this view of the Nerves of Respiration, (ur.ginating in the Medulla Oblongata, which is an extension of the Cerebellum, (b) or seat of Voluntary Motion, and of the Cerebrum, (a) or seat of Rationality,) may be seen the nerve (c) that goes to the Diaphragm ((,) and is concerned in the office of breathing, which generally acts without the aid of the Will; but yet is controllable by the Will, to a certain extent; for we may breathe fast or slow, long or short. Next above this, is the Spinal Aceessory Nerve, used in moving the breast, &c., in respiration ; one of its fellow roots goes to the tungue (d,) and is concerned in mastication, swallowing, speaking, &c. (Some nerves are thrown back, the better to be seen.) Next in order is the 7.

This seat of the Motive power of the body; and from is a very correct representation of the Osseous these proceed the spinal marrow, (me,) enveloped system, or the bony paris which may be apuy in three different membranes, lying in the hollow of the back bone, and branching off by thirty pairs of spinal nerves into a great many ramifications over every part of the body; pb, the brachial plexus, a reunion or assemblage of the different nerves distributed to the arms, or upper extremities; and ps, the plexus, or folds of nerves, that form the great sciatic nerves, descending to the legs, or lower extremities. From the spinal marrow, the nerves arise by two sets, or bundles of roots; the front (anterior,) one serving for motion, and the back (posterior,) are the nerves of feeling, or sensibility. Now, in all voluntary actions of the body, whether reading, speaking, singing, or working, there should be a perfect harmony and co-operation of the Organic Nerves, Respiratory Nerves, and Molary Nerves; hence, the volunary effort must be made from the abdomen, where is the great centre of Organic Nerves, in connection with those of Respiration.

is to emancipate the human mind from the darkmess and slavery of ignorance, into the light and *iberty of rational humanity. The things of the Animal kingdom live, and move from an interior power; those of the Vegetable kingdom grow; and those of the Mineral kingdom do not live or grow; they simply exist. 11. Three objects are designed by this engrawing: first, to show the body, clothed in its own beautiful envelop, the skin, which is the contizent of our most wonderful piece of Mechanism: second, to call attention to the fact, that it is full cf pores, or little holes, through which passes out

ble perspiration, which is indicated by the cloudy mist, emanating from every part of the surface; and as our bodies wear out, by degrees, and are renewed every seven years, and the skin being the principal evacuating medium for the worn-out particles of the system; the great importance of keeping it in a clean, and consequent healthy condition, by daily washing in soft cold water, must be evident to every one of reflection, it being the safety-valve of the body: and thirdly, to indicate a higher truth, that of the passing off of a subtle and invisible fluid from the mind, in accordance with its state; which is often perceived when certain persons are present; also when powerful speakers are pouring forth their highly wrought affections, and brilliant thoughts; so as wo give the mind a kind of ubiquity, co-extensive with their tones and audible words, ruling immense audiences with absolute sway, and demonstrating the power of truth and eloquence. Animals and Plants increase by nutrition: Minerals by accretion. In infancy, we weigh but a few pounds: at adult age, we exceed one hundred pounds. Whence, but from foreign substances, are the materials of which our organs are composed? In sickness, extreme emaciation proves that our bodies may lose a portion of their bulk, and give back to the world what was once its own. Thus, composition and decomposition,

constituting the nutritive funct or of wh:eh living bodies are the centre, are revealed to us by evidences too plain to be misunderstood: may we have power to appreciate them, being assured that all truths are in perfect harmony with each other. 12. Here is a representation of the Human Form clothed and engaged in some of the uses of Elocution. But it is necessary to enter more

into the particulars of our subject; which is $ons in the succeeding parts of this introduction: however, let the reader bear in mind, that only the out. lines of subjects are given in the book, designed for such as are determined to dig for truth and eternal principles, as for hidden treasures; whose motto is “Press On.” Animals and Plants endure for a time, and under specific forms, by making the external world a part of their own being; i.e. they have the power imparted to them of self-nourishment, and when this outward supply ceases they die, having completed their term of duration: hence, death, to material existences, is a necessary corsequence of life. Not so with minerals: they exist so long as external forces do not destroy them : and if they increase, it is simply by the juxtaposition of other bodies; and if they diminish, it is by the action of a force, or power, from without. Has not every thing its circle? How interesting must be the history of all things, animate and inanimate! Oh that we had eyes to see, and ears to hear, every thing that is manifested around us, within us, and above us! 13.

representation of which is here presented as seen through a microscope, magnified one thousand times. O Every three or four minutes, as a general rule, the blood flows thro'out the whole body; and, of course, through the lungs, where it undergoes a purification: hence may be seen the importance of an upright position, and perfect inflation of the lungs; no one can live out his days without them. 19. Here are two attitudes, sitting, and standing, passive and active. Beware of too much

stiffiness, and too much laxity, of the muscles; be natural and easy. Avoid leaning backwards or forwards, to the right or left: and especially, of resting your head on your hand, with the elbow on something else: by which practice, many have caused a projection of one shoulder, induced spinal affections, &c. Beware of every thing that is improper: such as trying how much you can list with one hand, &c.
