e and assist others in a matter, which, to be well
prosecuted, will require many hands. At the reading of them, the _Author_
declared, that of divers of them he thought he could fore-see the Events,
but {386} yet judged it fit, not to omit them, because the Importance of
the _Theories_, they may give light to, may make the Tryals recompence 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 _Quaeries_ or
proposed _Tryals_.

_The _Quaeries_ themselves 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?)

4. Whether acquired Habits will be destroy'd or impair'd by this
Experiment? (As whether a Dog, taught to fetch and carry, or to dive after
Ducks, or to sett, will after frequent and full recruits of the blood of
Dogs unfit for those Exercises, be as good at them, as before?)

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 mass 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 {387} Vein opened of a Dog, the admitted blood will be found
to retain _Chyle_?

7. Whether a Dog may be kept alive without eating by the frequent Injection
of the Chyle o
