The spaniel, subsequently drained of an equal volume of its blood, survived in robust health, while the mastiff met a tragic demise before the eyes of the assembled Society. This macabre spectacle served as a precursor to future endeavors in blood transfusion. Unshakeable Confidence PLR Review, Bonus, Earning

Jean Baptiste Denis’s Bold Endeavor (1667)

Taking inspiration from the London experiment, the royal physician to Louis XIV, Jean Baptiste Denis, conducted a more audacious undertaking in 1667. Faced with a 15-year-old boy weakened by excessive blood-letting, Denis injected about half a pint of lamb’s blood into the boy’s veins. Reports of the time indicate a marked improvement in the boy’s condition, providing a glimmer of hope for the potential of blood transfusion in medical interventions.

Arthur Coga’s Unconventional Transfusion (1667)

The Royal Society in London, emboldened by Denis’s success, continued its exploration into blood transfusion. In 1667, Arthur Coga, described as a slightly ‘frantic’ divinity student from Cambridge, became a subject for a transfusion experiment. Sheep’s blood, half a pint in quantity, was introduced into Coga’s veins with the hope of cooling his blood and mitigating his supposed madness. This bold experiment reflected the evolving and experimental nature of medical practices during this period.

Denis’s Continued Pursuit and Legal Repercussions (1668-1670)

Despite the success achieved by Jean Baptiste Denis in subsequent transfusions, a setback occurred in 1668 when one of his patients succumbed after a third transfusion. Legal troubles ensued, with Denis facing accusations and a court case initiated by the deceased patient’s widow. Though he was acquitted of murder, Denis’s fortunes took a downturn. In 1670, France, reacting to the potential risks and ethical concerns, passed a law making blood transfusion illegal, casting a shadow over further exploration in this field for the next two centuries.
