 yet judged it fit, not to omit them, because the Importance of the Theories, they may give light to, may make the Tryals recompense the pains, whether the success favour the Affirmative or the Negative of the Question, by enabling us to determine the one or the other upon surer grounds, than we could otherwise do. And this Advertisement, he desires may be applied to those other Papers of his, that consist of Quæries or proposed Tryals.

The Quæries themseves follow.

1. Whether by this way of Transfusing Blood, the disposition of Individual Animals of the same kind, may not be much altered; (As whether a fierce Dog, by being often quite new stocked with the blood of a cowardly Dog, may not become more tame; & vice versa, &c.?)

2. Whether immediately upon the unbinding of a Dog, replenisht with adventitious blood, he will know and fawn upon his Master; and do the like customary things as before? And whether he will do such things better or worse at some time after the Operation?

3. Whether those Dogs, that have Peculiarities, will have them either abolisht, or at least much impaired by transfusion of blood? (As whether the blood of a Mastiff, being frequently transfused into a Blood-hound, or a Spaniel, will not prejudice them in point of scent?)

5. Whether any considerable change is to be observ'd in the Pulse, Urin, and other Excrements of the Recipient Animal, by this Operation, or the quantity of his insensible Transpiration?

6. Whether the Emittent Dog, being full fed at such a distance of time before the Operation, that the mess of blood may be suppos'd to abound with Chyle, the Recipient Dog, being before hungry, will lose his appetite, more than if the Emittent Dogs blood had not been so chylous? And how long, upon a Rh
