TRANSLATED FROM THE FRENCH, BY A. R. MACDONOUGH, ESQ. IN all ages essentially the most totally different opinions as to the seat and the principle of life have been expressed; yet, the systems bequeathed to us by the ancients on this topic contain a common belief, easy enough to be very widely shared, and seemingly well based enough to endure for BloodVitals test centuries. One truth of commonest statement demise ensuing from haemorrhage gave rise to the notion that life dwells solely in the blood. Homer's heroes breathed out their souls with their blood; among the many Hebrews, as among the Greeks, providing the sacrifice of a life, BloodVitals test and shedding the blood of a victim, have been equal expressions. From Galen to Harvey, men of science supposed that the center solely sends out the fluid of the blood from the centre to the floor. Of their theories, the blood was incessantly formed and renewed within the liver, and at-home blood monitoring was impelled by centrifugal force into the veins and arteries alike.



Harvey first demonstrated that the blood returned in its course. The concept of the transfusion of blood takes its starting-level from the discovery of Harvey. As quickly as it was known that the blood can return to the center, and be taken up once more by the vessels, what was more natural than to hunt to introduce it right into a diseased physique? Isn't the blood still regarded as the only precept of life, as it was within the early ages of medicine? And, since it may be transfused in form, we shall be ready to revive health, to heal disorders, perhaps, even to lengthen life. In a second of pleasure the human mind believes it has penetrated the secret of life, and supposes that henceforward will probably be its master. The most famous alchemists of the middle ages by no means surrendered themselves to hopes so wild. Besides, the sixteenth and seventeenth centuries noticed the delivery of so many discoveries in pure sciences, BloodVitals test that nothing seemed impossible.



The colleges of medicine enter with feverish ardor BloodVitals test on these questions, BloodVitals home monitor so stuffed with promise; but, amid the sunshine that bursts upon them, BloodVitals tracker they typically neglect that severe remark of facts which led to the discovery of the circulation. Physicians of that day hassle themselves little or no with inquiries whether the historical notions concerning the blood are true or false; they accept them with out reserve, and publish them abroad with those forms of dialogue and people obsolete rules which brought upon them the properly-deserved ridicule of our satirists. Medicine and BloodVitals test physiology in that era have been treated underneath the type of philosophic argument, science and imagination were blended, and "reasoning banished reason." The history of transfusion, at its beginning, appears to be like like an vital but empirical discovery; new experience rests merely on scholastic discussions, the true mingles with the false, and, after the spectacle of a barren contest offered by detractors and BloodVitals test fans, transfusion was proscribed, and doomed to oblivion; and it will be long before its recovery, for the true scientific methodology has not but been found.



Within the last half-century now we have returned to the strategy of statement; nor is that technique now, as it was in Harvey's time, BloodVitals SPO2 the privilege of some savants; it has grow to be the information of all males of science in our day, and the actual cause of scientific progress. Amid the final growth of the sciences, transfusion has come up as soon as extra, transformed and widened; it will not fulfill the extravagant hopes indulged at first, real-time SPO2 tracking however it is going to throw a broad mild on the problem of health and illness. The rules on which this grand experience now rests are properly settled-the functions of the blood have been clearly determined. We all know that life dwells in each 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, but stay by themselves. If general anatomy has adopted out the work of Bichat, in studying the weather of useless Nature, physiology has realized Haller's conception, in analyzing the capabilities of those elements.
