 same or a different kind, and separate it from the Nerve of the Eight pair, and lay it bare above an inch. Then make a strong Ligature on the upper part of the Artery, not to be untied again: but an inch below, videl. towards the Heart, make another Ligature of a running knot, which may be loosen'd or fastned as there shall be occasion. Having made these two knots, draw two threds under the Artery between the two Ligatures; and then open the Artery, and put in a Quill, and tie the Artery upon the Quill very fast by those two threds, and stop the Quill with a stick. After this, make bare the Jugular Vein in the other Dog about an inch and a half long; and at each end make a Ligature with a running knot, and in the space betwixt the two running knots drawn under the Vein two threds, as in the other: then make an Incision in the Vein, and put into it two Quills, one into the descendent part of the Vein, to receive the bloud from the other Dog, and carry it to the Heart; and the other Quill put into the other part of the Jugular Vein, which comes from the Head (out of which, the second Dogs own blond must run into Dishes.) These two Quills being put in and tyed fast, stop them with a stick, till there be occasion to open them.

All things being thus prepar'd, tie the Dogs on their sides towards one another so conveniently, that the Quill may go into each other, (for the Dogs necks cannot be brought so near, but that you must put two or three several Quills more into the first two, to convey the bloud from one to another.) After that, unstop the Quill that goes down into the first Dog's Jugular Vein, and the other Quill coming out of the other Dog's Artery; and by the help of two or three other Quills, put into each other, according as there shall be occasion, insert them into one another. Then slip the running knots, and immediately the bloud runs through the Quills, as through an Artery, very impetuously. And immediately, as the bloud runs into the Dog, unstop the other Quill, coming out of the upper part of his Jugular Vein (a Ligature being first made about his Neck, or else his other Jugular Vein being compress'd by ones Finger;) and let his own bloud run out at the same time into Dishes (yet not constantly, but according as you perceive him able to bear it) Rh
