Part 6

The menstruum is supposed to act by "chymical attraction," from having "chymical affinity" on the involved "chymical solid," which enables it to draw out the elementary atoms of the solid: whereas the inert menstruum does nothing; it is but an interstitial recipient for the atoms to be forced into, as they become centrifugally forced out of the solid. And because the atoms of a body are of different sizes, some make novel interstices, and thus expedite the dissolution. Only by increasing the number and kind of interstices, can diluting a menstruum with water increase what is imagined to be its solvency. Neither chymical properties, nor chymical strength of a fluid, if it had any such, could be increased by dilution, and the stronger should dissolve that which the weaker is said to dissolve. The contrary supposes that the force which breaks a stone is too strong to break a nutshell. Mechanical dissolution by the centrifugal pressure is independent of chymicalities.

Gastric solution is effected similarly: the juice has none of the chymical properties of Liebig, nor does ingestion stand in need of the living principle of Coombe; the former are imaginary, the latter is denied from gastric solution taking place in a tea-cup. The gastric juice is an interstitial receiver of the elements of the pulp, when forced out by the centrifugal pressure into the gastric menstruum, as those of soap into water. The pulp and its striæ are disunited, mechanically decomposed, not abraded: some of its elements escape into the air within the stomach, which, by disturbing the equilibrium within, promote irregularity of pressure on the outside of the sac, which causes the pliæ to be in the peristaltic motion, supposed to be caused by the stomach stimulating itself. The same circumstances take place within and without the intestines. The whole process of digestion is dynamic, in which the only stimulant is pressure.

Of the various conjectures on the origin of the gastric juice, there cannot be any more unreasonable than that which considers it a fluid sui generis, and as having origin out of the stomach. All fluids are compounds; and those belonging to the body may be said to be formed out of, or by commixture with others. To suppose for an instant, that a fluid, which is destructive of all flesh, should have existence out of the stomach, and remain harmless in some fleshy vessel as long as the stomach is empty of food, or until food is required to "stimulate" its flow from without through the papillæ of the villous lining into the stomach, is a most strange physiologic oversight. Why not rather conclude at once, that the flesh-destroying juice exists only where it is required and for immediate service, and where only there are preventive means, the peristaltic motion, against it proving injurious to the flesh of the stomach; and to the vessels of secretion it would be injurious, hence, not as the juice but chyme it is passed out of the stomach into the system. Under such circumstances, the suggestion is nothing unreasonable, that, there is no gastric juice out of the stomach, nor within, but while there is food present to contribute one or more of its elements to the other juices, including the saliva, towards effecting its completion as a fit interstitial gastric menstruum, for receiving the elementary constituents of the pulp under mechanical decomposition by the centripetally disuniting pressure of the medium of space. Like the all de-electrising medium of fire, which exists only where and while it is being formed, the gastric juice should be looked upon as if designed to be of difficult formation; made more so by depending on the food for its completion, which is not a matter of "observation" within the stomach, or in the tea-cup: neither is the perfect juice, which may be sponged or syringed from the bottom of the stomach, any proof that as such precisely it came from the papillæ, as some suppose. As to the papillary flow being stimulated by the food, with as bad philosophy it might be said, charmed; or that clockwork is stimulated by the weights. The flow is promoted by the pulp, as were the latter a piece of sponge. And that the papillary flow is but a constituent, not the flesh-destroying juice, in promoting ingestion, is evident from the hunger pain it promotes while harmlessly accumulating out of the stomach, indicating the stomach being empty; and the relief experienced at its source when discharged into the stomach, it is, which has given rise to the idea, that certain organs sympathise with the stomach.

Such metaphorical expressions may pass for the poetry of pathology, but hitherto have stood in the way of deep research. Ingestion is expedited by sleep, in consequence of the accumulation of minus-pressure matter in the gastric region and stomach at the time; and sleep is promoted by imperfect mastication causing a deficiency of saliva in the stomach which is compensated by minus-pressure matter of the thus provoked comatose flow. The pollparrot masticates but little, if at all, and sleeps regularly after breakfast.

USE OF THE INSPIRED OXYGEN WITHIN THE SYSTEM.

There is none of the inspired oxygen returned to the lungs by the circulation. What becomes of it, or what its use within the system, has not been written for our learning. It is not retained in the blood, nor is it animalised; nothing yields less oxygen than animal matter. To convey "carbon" out of the system, and somehow purify the blood, is the supposed service; but if so, should it not be included in every expiration and of the inspiration quantity? but which is not the case.

Harvey proved that the blood circulates, but left undiscovered what keeps in motion the inert fluid, except the systole, which the inert heart cannot effect on itself. No organ can do anything of itself, the whole being composed of inert substance, and nothing else; even the life of the body, whatever it may be, leaves the function of every organ, not excepting that of the brain, dependent on the general pressure.

By the general pressure the air is forced into, but not through or beyond the lungs which it inflates, and inflates nothing else. Within the blood-vessels it would prove fatal; and although from it the blood derives that by which it becomes arterialised, yet the blood and air do not come in contact, extravasation and pulmonary rupture must happen, did the lungs permit the blood and air coming together, or in immediate contact. Of the air of an inspiration, the oxygenating imponderable element only can permeate the pulmonary tissue. This element it is which imponderably arterialises the blood; the nitrogen of the inspiration constitutes the immediate succeeding exspiration.

The oxygenating element promotes the circulation on the same principle that it promotes combustion; its diminutive interstices exclude electric matter, which coagulates, and admits the propelling force, medium of space, which is the only cause of motion, to enter the blood. The oxygenated blood being propelled, or pressed, by the medium of space it includes, from the lungs into the ventricle, the collapse, or systole, takes place, and the blood is forced out of the ventricle, through the auricle, into the aorta, thence through the several branches of the arterial system, to and through the capillaries, into the veins. Thus, from the medium of space within the blood being continuous with the medium of space generally, it is manifest that the blood is circulated not by the systole, but by the general pressure. To produce the systole, there is nothing but the normal pressure on the outside surface of the heart; nor, to lessen the normal pressure on the parietes of the ventricle, is there anything but the arterialising, minus-pressure, imponderable element of the blood just received into the ventricle.

Throughout the entire of the arterial flow, the blood is losing the arterialising minus-pressure matter to the different organs, as the means by which the functional action of each is promoted. Without such means, there is nothing to disturb the equilibrium of pressure on an organ to produce organic motion, action, or function. Hence, it appears, that the use of the inspired oxygen consists in promoting the circulation of the blood and the functional motion or action of the different organs within the frame.

Before entering the veins the blood is fully deoxygenated; within them it acquires gradually electric matter, productive of the livid or coagulating appearance; at the same time the blood-propelling medium is lessening in quantity; but which is compensated in the mucilaginous lining of the veins, which assists the venous flow on the minus-pressure capillary principle; capillary attraction would collapse the vessels. The electric matter collected by the venous blood is got rid of in the lungs, and expired with the nitrogen and a remnant of the oxygenating element of the last inspiration; hence the small portion of carbonic acid gas obtained from the expiration.

After all organic service, the arterialising minus-pressure matter is insensibly transpired, which is inferable from the supply being continued through respiration; which, although constant, yet, from being intermitting, might, perhaps, cause corresponding stoppings in the round of organic action; hence it would seem that, against such intervals or interruptions taking place, the liver has been designed to collect for casual distribution a portion of the same minus-pressure matter. The great surface of the liver may stand comparison with the plate, or cylinder, of the electrifying machine, and the organs as jars which receive electric matter from it, as each stands in need.

Use of the Spleen.--The SPLEEN, from being an organ common to the human frame, must have an allotted service to supply; although considered useless by some, to all of unknown utility, it may be a lateral channel of arterial blood direct from the heart, to supply the vessels lying in a portion of the body not traversed by the arteries belonging to the great arterial system; those of the diaphragm first; thence through the umbilical cord to the fetus, in which the circulation is indispensable, from being the only means of conveying and dispersing throughout the body, in the absence of respiration, the minus-pressure matter which the organism of the fetus requires to promote the several functions, without which life would become extinct if commenced. In this supply of motion promoting elementary matter, consists all that can be considered aeration of the blood, and all that the blood of both the fetus and the adult requires, or can possibly receive. In the chirping chick, while within the yet unbroken shell, aeration is prevented by incubation of the mother bird; but the arterialising elementary matter is amply provided within the larger, apparently empty, end of the shell. To keep out electric matter, which would exclude the blood-moving medium, is the object of the hen sitting on the eggs, and oven-hatching is effected on the same principle.

How the Diaphragm Is Raised.--The diaphragm cannot rise of itself, and has no self-acting, self-lifting nerves or muscles, all flesh being composed of inert atoms. The rise is proof positive that pressure is greater on the posterior than anterior surface of the membrane, and the unchanged normal pressure beneath indicates reduced pressure above; the latter is promoted by minus-pressure matter imparted by the splenic blood to the diaphragm, while passing through the vessels of the diaphragm. This arterialising matter being highly evanescent, escapes from the diaphragm and upwards, and during the escape mitigates the pressure, intercepts it in some degree from the superior surface; then, by the normal pressure beneath, the rise of the diaphragm is effected. As the escape, or separation, is becoming complete, the equilibrium is being restored, and the diaphragm depressed to the normal level. If this be not the rationale of diaphragmatic motion, it will be little improved by the substitution of muscular energy, leverage, or muscular vitality, while leaving out muscular inertia, which should not be omitted, but included, in accounting for every muscular action and motion.

CORRELATIVE ELEMENTS.

Any pair of the general elements, the interstices of one of which are the only interstices for receiving and retaining the atoms of the other, or that can be occupied by the atoms of any other of the general elements, such elements are correlatives.

Elementary co-relation is conspicuous in the opposite polarities of the loadstone, magnet, and crystals, and all bodies subject to polarization, which includes the animal frame. Similar co-relation is evinced between the galvanic fluids, those of the pile, and those named electricity; likewise between oxygen and hydrogen, the oxygenating element and nitrogen, acids and alkalies and all mutually neutralizing substances. Still it is not meant that all the general elements are so paired; doubtless, there are several ratios of size between the atoms of the different elements, for the purpose of multiplying variety among formations, the substance of which is of the same species throughout. Possibly the correlative principle gave rise to the ideal scale of chymical affinities, subsequently refined to affections of matter. Naturally, correlative elements will be found together, as are nitrogen and the imponderable element; also the magnetic fluids common to iron.

MAGNETISM.

Were attraction a property of the atomic substance of the loadstone, it could be neither transferable, receivable, nor liable to be destroyed by fire. A magnet is a work of art, the substance is inert, it can no more attract than think. Magnetism is an accident of matter; it consists in the correlatives of an iron bar having become separated, and drawn one to each end of the bar: separation and transition to the extremities of the bar, are what the rubbing on the poles of the loadstone effects.

Two paving-stones hanging a short distance asunder and touched by nothing but the tranquil air, remain at rest; but should attract each other had "every atom in creation" the property. Were a vacuum, partial vacuum or air much rarer than atmospheric, now placed between the suspended stones, each would be in motion towards the other the same instant. Here both causes, the general pressure, and the minus-pressure, or motion promoting means, are given; the latter are sensibly present, and the absence of attraction is as evident as the inutility of anything of the kind to effect the mutual approach of the two bodies. Not so is the approach of two magnets understood, because the intermediate minus-pressure means present are not sensible. That iron magnets do not move together by attraction, or that attraction is not the cause of the phenomena imputed to it, is proved in the case of iron-filings dropping from a bar, when the connection of the bar with the galvanic battery is broken; and it will not be contended that the galvanic current is attraction.

In order to arrive at a knowledge of wherein consists the means which subvert the equilibrium between two suspended magnets, reference has to be made to the artizan's mode of operating in converting the unmagnetised bar to a magnet. He holds the bar in the middle, and draws one half along the pole of a loadstone; then draws the other half along the other pole, and after a few such alternate rubbings against the poles, the bar is a polarized magnet. From which it was formerly supposed, that iron contains a magnetic fluid which the loadstone rubbings divide, and draw half to each end of the bar. But were such the fact, the ends or poles should be equals, whereas they are magnetic opposites. Now, with more reason, it is considered that iron includes two different, removable elements, (correlatives,) which, by the manipulation on the loadstone, are drawn one to each end of the bar, and there remain as polar atmospheres, and constitute what are termed the polarities, or opposite polarities of the bar; the latter opinion is somewhat confirmed by the corresponding manner in which iron filings, while being scattered on a sheet of paper, become arranged round the poles of a magnet lying under the paper.

The magnetic relation, which the polar atmospheres of any iron magnet bear to those of every iron magnet, being the same as exists between the polar atmospheres of every individual magnet, makes manifest, that a certain pair of correlative elements is common to all magnetisable iron; but without concluding that, by the same kind of correlatives, the polarities are produced in bodies not ferruginous, which, if the physical fact, so may the animal correlatives be different in some instances. From which it follows, that no one mesmeriser can affect mesmerically every person, nor any one person be so affected by all mesmerisers. Neither are all persons "nervous" alike, which should moderate the war cry against mesmerism generally because of failure in some cases; and should awaken the philosophic mesmeriser, willing to make perfect the science, to investigate the cause of exceptions and difficulties.

Now, as respects the interposed minus-pressure means or matter, which, by destroying the equilibrium, promote the approaching motion of two suspended magnets; there is nothing whatever to refer to, but the magnets themselves, that is, their polar atmospheres, which, together or facing one another, make a rare or minus-pressure medium between the proximate ends, into which both magnets are moved by the greater pressure on their remotest ends. It lies with the previously-instructed patient, while clairvoyant, through questioning by the mesmeriser, to make close observation, and report all circumstances respecting the magnetic lights; also, those attached to and proceeding from the mesmeriser, towards elucidating this most of all recondite subjects--magnetism, in the philosophy of physics. The mesmeriser should hold in mind, that, probably the air between the facing ends of two magnets is magnetically affected, that is, made a magnet in the series by the other two; which seems to be the case when the patient is magnetised at a distance from the mesmeriser by means of the pointed finger, and by the effect of will at a much greater distance.

NATURAL SLEEP.

That sleep is not at the command of will is certain, or why undergo the tedium of a restless night? Before the state of sleep can obtain, the body has to experience an electro-physico change, by which the extremities are left polarised and the body an animal or living magnet. That the extremities are polarised during sleep, is admitted by all physiologists; for the effecting of which there must be a pair of correlative elements concerned. While the elementary transfer, productive of the polarities, is taking place, so is drowsiness; when sleep has obtained, the natural magnetising procedure has terminated; hence from the degree of polarity, the mesmeriser can determine the stage to which the patient has been brought between the comatose and clairvoyant states, and know the capability of his patient for being made clairvoyant or not; this polar index should be well noticed.

Comatose Flow.--It must have been observed by many persons while dozing and the body in a sitting or leaning posture, that an agreeable warm glow arises in the chest, which increases while passing sensibly through the pectoral towards the gastric region, and which terminates, insensibly, in the consummation of sleep; from the feet upwards a similar, but less perceptible, flow takes place. Of this twofold comatose flow, the immediate consequence is polarisation of the extremities; sleep is a remote, but not the remotest consequence, when effects similar to those by the flow are mesmerically effected. Thus it appears that the theory of sleep and magnetism is the same. The magnetising procedure, however, has this difference; the magnetic correlatives are drawn from the middle to and out of the extremities of the bar; those of the body of the patient recede from the extremities to the central region, leaving one, the correlative of the other, at each extremity, in both cases.

The foregoing theory of sleep is described from immediate personal observation. While leaning over a table, the doze heavy, the comatose flow distinctly felt in its agreeable downward progress through the chest, when, just at the instant of forgetfulness, the violent slam of a door drove away all chance of sleep under the following circumstances: a sensible and sudden revulsion upwards, a few seconds of giddiness, and a smart painful stroke on the stomach took place, all in quick succession; which may be accounted for thus: the slam prevented the correlative fluids from the opposite extremities meeting centrally; each gushed irregularly back, and depolarized its extremity, the suddenness of which caused the giddiness. The stroke is the true electric shock, inflicted by the medium of space suddenly rushing or falling on the stomach, from which the matter of the comatose flow had been as suddenly displaced. Taking all circumstances into consideration, it is manifest that the state of sleep is the result of a natural magnetizing operation.

Before the fire, while reading, the superior extremity loses electric matter to the fire, which leaves it polarized and promotes the comatose flow. The lower extremity becomes polarized simultaneously with the upper as a correlative consequence. Sleep is supposed to be expedited by heat; hence the afternoon's nap is seconded by a silk handkerchief thrown over the head, but which is only a hindrance to electric matter, similar to that of the comatose flow entering from the air and depolarizing the extremity. The handkerchief, from being a non-conductor, only prevents the coming sleep being retarded; it could neither generate nor multiply heat.
