which swounded, and remained as dead for half a quarter of an hour: And when some alledged, that the Dog died, because he was wounded in the neck, where he could not lick himself, which rendred his wound incurable, answer was given, that Experiments had been made, wherein not only a Vein was opened, but also an Artery, yea, even the Aspera arteria cut of a Dog, that could not lick himself, and yet survived.
This whole Account is concluded with an Admonition, that all those, who have convenience, would make frequent and exact trials of this Experiment on Brutes, and carefully observe Weight and Measure, and all other circumstances, before any thing be hazarded, that may damnify the publick, and depreciate the Invention.
Abundans cautela non nocet, is a Maxime very fit to be minded here; though several succesful Experiments have been made in London, of very plentiful Transfusions; and among others (to mention a signal one) that upon a Bitch, which lost in the operation near 30 ounces of blood, and was recruited accordingly. This Animal does not only survive to this very day, but had another more severe Experiment soon after tryed upon her, by which her Spleen was cut out, without tying up the Vessels, whence that viscus was separated: Since which time (even before the wound was healed up) she took dog, was with Puppy, and brought forth Whelps, and remains well and jocund, being kept for a piece of remarquable Curiosity in the House of a Noble-man, that is as severe in Examining matters of fact, as he is able in Judging of their consequences.
So that it is not too hastily to be concluded, that large Transfusions are dangerous; but rather frequent Experiments should be made, before any thing be therein determined, with great as well as smaller quantities, both upon sound and sickly Beasts, carefully observing, how either is endured in either, and what are the Effects following thereon.
Before we dismiss this Subject, something is to be said of the Cause, why the Curious in England make a demurr in practising this Experiment upon Men. The above-mentioned ingenious Monsieur Denys has acquainted the World, how this degree was ventured upon at Paris, and what good success it there met
