is affirmed in that Letter about the time and place of the Conception of that Transfusing design; and intimated to the Curious, that how long soever that Experiment may have been conceived in other parts (which is needless to contest) it is notorious, that it had its birth first of all in England; some Ingenious persons of the Royal Society having first started it there, several years ago, (as appears by their Journal) and that dextrous Anatomist, D. Lower, reduced it into practice, both by contriving a method for the Operation, and by successfully executing the same: wherein he was soon overtaken by several happy Trials of the skilful hand of D. Edmund King, and others, encouraged thereunto by the said Society; which being notified to the world Numb. 19. and 20. of these Transactions, Print-Novem. 19, and Decemb. 17. 1666; the Experiment was, soon after that time, heard of to have been tried in forein parts, without hearing any thing then of its having been conceived ten years ago.
1 . Having infused into the Jugular and Crural Vein of a Dog some Aqua fortis diluted, the Animal died presently; and being opened, all the bloud in the Vessels was fixed, but that in the guts not so well. It was also observed, that the great vessels were burst, perhaps by an effort of Nature; even as in the greatest part of those that die of an Apoplexy, the vessels of the Lungs are found broken. Upon which Experiment the Author maketh these Reflections: First, That an Apoplexy being often caused by a like Coagulation of the bloud (as hath been observed by the opening, made of sundry persons, who died of that distemper) it might be cured by a timely infusing some Dissolvent into the veins. Secondly, That it is likely, that that useful secret, by which Monsieur de Bills dissected Animals without any effusion of bloud, consists in some such Infusion.
2. There was afterwards infused into another Dog some Spirit of Vitriol, which had not so present an effect; for the Animal complained a great while, and foam'd like Epilepticks, and had its respiration very thick; and observing the beating of his breast, one might easily judge, the Dog suffered much: who dying at last, his bloud was found fixed in the veins, and grumous, resembling soot.
3. Then there was injected into a Dog some Oyl of Sulphur: But he died not of it, though this Infusion was several times tried upon him. And
