Human blood

“ He maintains, and it is true, that, by using very high magnifying powers and taking much trouble, an expert can satisfactorily identify human blood, if he has some half-dozen drops of blood from different animals—such as the sheep, goat, horse, dog, cat, &c., all fresh at hand for comparison, and if the human blood is normal. ”

“ However, when we come to the blood of persons suffering from disease, there are changes in the diameter and even the form of the corpuscles which much complicate the matter; while, in blood-stains of any age, the blood-corpuscles, even with the most artfully-contrived solvent, are so distorted in shape that he would be a bold man who should venture on any definite conclusion as to whether the blood was certainly human, more especially if he had to give evidence in a criminal case. ”

“ Believing that all disease, of whatsoever nature, can be safely treated only through the blood, this ill to which human flesh is heir particularly must be treated in that way, for we know that a stagnant state of the blood in one spot, at least, is the cause of the patient's malady. Therefore I have been experimenting botanically to discover a remedium for the state in question—something that will act swiftly upon the blood, and directly dissipate such a clot as is spoken of above."
"My dear Professor! I can announce with joy that this remedium is discovered. ”

“ It is that the hemoglobin or red colouring-matter of the blood forms crystals. That has long been known, but working on this fact Dr. Reichert and Professor Brown of the University of Pennsylvania have made some wonderful discoveries.
"We could distinguish human from animal blood before, it is true. But the discovery of these two scientists takes us much further. By means of blood-crystals we can distinguish the blood of man from that of the animals and in addition that of white men from that of negroes and other races. ”

“ In such a case bleeding should not be again resorted to, but the deranged residue should be subdued by means of pacifying or absorbing remedies.
Blood is the origin of the body. It is blood that maintains vitality. Blood is life. ”

“ In these ceremonies, it is evident that the Zuñis, like the Orientals, [307] recognize the blood as the life, the heart as the epitome of life, the liver as a congealed mass of blood, and the transference of blood as the transference of life. Moreover, there is here a trace of that idea of the revivifying, by blood-bathing, of a being that had turned into stone ”

“ The Blood is the Life—never be Bled!—"He who loses a pint of blood, loses a pint of his life. Of what is the body composed? Is it not of blood, and blood only? What fills up the excavation of an ulcer or an abscess? What re-produces the bone of the leg or thigh, after it has been thrown off dead, in nearly all its length? what but the living BLOOD, under the vito-electrical influence of the brain and nerves! How does the slaughtered animal die? ”

“ Once it was recognized that the state of unconsciousness or death was due to the loss of blood it was a not illogical or irrational procedure to imagine that offerings of blood might restore consciousness and life to the dead. [255] If the blood was seriously believed to be the vehicle of feeling and knowledge, the exchange of blood or the offering of blood to the community was a reasonable method for initiating anyone into the wider knowledge of and sympathy with his fellow-men. ”

“ The elements of the blood are derived from the chyle, and, if it be vitiated, the blood also must suffer: if the blood be diseased, so must necessarily be all the organs which it supplies; and if the body be thus debilitated, can any wonder be felt that it should no longer be able to resist the action of offending causes which full health alone can withstand? ”

“ That the blood of the living has a peculiar vivifying force, in its transference from one organism to another, is one of the clearly proven re-disclosures of modern medical science; and this transference of blood has been made to advantage by way of the veins, of the stomach, of the intestines, of the tissue, and even of the lungs—through dry-spraying. ”

“ The interesting part of the experiment to us is, that if serum only, without globules, be restored to the unfortunate animal, it is of no use whatever, and the corpse does not revive.
It is evident, then, that all the power and virtue of the blood lies in the globules; and according as their number is great or small it is "rich" or "poor," as it is called; and where their number is not up to the mark, the blood acts more feebly on the organs, life is calmer, and people are no longer troubled with emotions—in other words, with violent heats of the blood. ”

“ The properties of blood are of great importance from a medico-legal point of view."
"Can you tell us what happens when a drop of blood—say from a cut finger—falls upon a surface such as the bottom of an iron safe?"
"A drop of blood from a living body falling upon any non-absorbent surface will, in the course of a few minutes, solidify into a jelly which will, at first, have the same bulk and colour as the liquid blood." ”

“ In order, therefore, to relinquish its seat of origin, and enter constricted and colder places, and move in opposition to its bent, [261] the blood has need not only of violence but of an impeller, such as is the heart alone, and after the fashion described already. ”

“ Indeed, there is nothing to be met with in the animal body prior to the blood, or more excellent; nor are the spirits which they distinguish from the blood to be found anywhere separate from it; for the very blood itself, if without spirits or heat, does not deserve the name of blood, but of cruor.... ”

“ By what incomprehensible mechanism are our organs held in subjection to sentiment and thought? How is it that a single melancholy idea shall disturb the whole course of the blood; and that the blood shall in turn communicate irregularities to the human understanding? ”

“ Is not the blood, then, in the impressive language of Scripture, 'the life of the flesh?' How remarkable, that while the value of the blood to the animal economy should be thus so distinctly and emphatically acknowledged, blood-letting is not even once alluded to, among the various modes of cure mentioned in the sacred volume. We have 'balms,' 'balsams,' 'baths,' 'charms,' 'physics,'—'poultices,' even—but loss of blood, never! Had it been practised by the Jews, why this omission? Will the men who now so lavishly pour out the blood, dispute its importance in the animal economy? ”

“ Amid the general development of the sciences, transfusion has come up once more, transformed and widened; it will not satisfy the extravagant hopes indulged at first, but it will throw a broad light on the problem of health and disease. The principles on which this grand experience now rests are well settled—the functions of the blood have been clearly determined. We know that life dwells in every fragment of our being; the mass of nerves, the flesh of our muscles, the tissue of our glands, need the indispensable assistance of the blood, yet live by themselves. ”

“ Indeed, the blood nourishes, fosters, and keeps alive all the parts which it constructs and adjoins to itself, even as the heavenly bodies above, especially the sun and moon, impart life to what is below, while they continue in perpetual circulation. Since, therefore, the blood acts beyond the powers of the elements and is potent with those virtues aforesaid, and also is the instrument of the supreme workman, no one ever will give praise enough to its wonderful and divine faculties. ”

“ It stands clearly proved that the blood is a generative part, the source of life, the first to live and the last to die, the primary seat of the soul; that in the blood, as in its source, the heat first and chiefly abounds and flourishes; and that by and from the blood all the other parts of the whole body are fostered and obtain their life by means of the influx of heat. Indeed, the heat which accompanies the blood floods, fosters, and preserves the entire body, as I have demonstrated already in my book on the motion of the blood. ”

“ The demonstration by physiology of the individual life of the parts, and the practical applications of transfusion, are wholly modern, as the circulation of the blood itself is. In ancient days the general belief was, that the life dwells in the blood, and yet some ancients seem to have had a suspicion that the elements of the organization live of themselves, and that, perhaps, the blood has a movement of circulation. ”

“ But it is necessary that the heart shall be assisted considerably, in the circulation 357 of the blood, by a contractile power of the vessels themselves; and the same quantity of blood is not to circulate in the same body at all times, for animals are liable to frequent injuries, by which the quantities of blood in their bodies may be very suddenly reduced. ”

“ Therefore, if I shall add the causes and uses of the circulation and reveal other secrets of the blood, showing how much it conduces to mortal happiness and to the welfare of soul as well as body, that the blood be kept pure and sweet by a right regimen, I truly believe that I shall do a work as useful and grateful to philosophers and physicians as it will be new; and that the following view will seem to nobody so improbable and absurd as it formerly seemed to Aristotle, viz.: that the blood, a domestic deity as it were, is the very soul within the body, as Critias and others thought of old ”

“ All my thought is, to ascertain what new meaning, if any, is found in the Bible teachings concerning the uses and the symbolism of blood, through our better understanding of the prevailing idea, among the peoples of the ancient world, that blood represents life; that the giving of blood represents the giving of life; that the receiving of blood represents the receiving of life; that the inter-commingling of blood represents the inter-commingling of natures ”

“ But I trust that we have facts enough to establish it as a certainty, 1st, That the black blood after the interruption of the chemical functions of the lungs, continues for some time to circulate, and 2dly, That it penetrates into the organs, where it replaces the red blood; these circumstances explain the reason, why on opening the body we always meet with black blood even in the vessels which are destined for the circulation of arterial blood. ”

“ The circulation of the blood maintains health, and consequently life by carrying away from the various parts of the body the particles of worn-out and poisonous tissue, and replacing them with fresh, structure-building material. ”

“ There is no part of the body, within or without, that has not a vast many small blood-vessels, running in every direction, that carry the blood to nourish all parts. But there are more blood-vessels in the skin than anywhere else, so that the quantity of blood in our skin is greater than all that is to be found, in all the rest of the body put together. ”

“ But when the blood is driven with violence from the veins into the arteries, forthwith there is disease; and the blood is poured the wrong way into the arteries, and there withstands and dashes itself against the breath of life coming from the heart, and turns the course of it—and this forsooth is fever. ”

“ As it was found that no animal could exist when suddenly deprived of large quantities of blood, it was inferred that this fluid was the vital principle; an opinion, indeed, which was much strengthened by the injunction of the Mosaic Law, not to eat meat in which there was blood, "that being the life." A late celebrated anatomist adopted this opinion, and boldly declared that the blood was alive. ”

“ For, when we speak of a 'blood relationship' uniting those persons who stand close to one another through ancestry, the word 'blood' doubtless represents a sort of reminiscence of the old idea of a blood soul. To the dispassionate eye of the physiologist, the blood is one of the most unstable elements of the body, so that, so far as the blood is concerned, the father and mother certainly transmit nothing of a permanent nature to their descendants. ”

“ The rite is, in some cases, observed after the manner of the Syrians, by the contracting parties tasting each other’s blood; while, in other cases, it is performed by the inter-transfusion of blood between the two. ”

“ We may just mention that as a general rule he approves of bleeding after any accident. He disapproves of bleeding both at the onset and the crisis of a disease. In constitutions requiring bloodletting he holds that spring is the best season for it. Even in cases in which there is a deficiency of blood, but there is congestion in some particular part, he permits blood to be abstracted, in order to produce revulsion, the patient’s strength being recruited afterwards by a nourishing diet. ”

“ Not but that blood is as necessary as breath for respiration, and food for nourishment of the body; but too much blood is as dangerous to the life of the animal body, as too great a piece of food, which cannot be swallowed down, but doth stick in the throat, and stop the breath, or so much quantity as cannot be digested, for too great a fulness or abounding makes a stoppage of the blood, or which is worse, causes the veins to break, and an evil digestion, makes a corruption, or at least such disorder as to indanger the whole animal Figure. ”

“ But the words of the second passage foreshadow a closely related doctrine, advanced and held by him on the evidence of observation, viz.: that the blood, being the first part to live, is also the last part of the body to die. ”
