was also hinted in the _method_ above) may be prepared and administred, to
bleed them all out into one.

2. It seems not irrational to guess afore hand, that the exchange of bloud
will not alter the nature or disposition of the Animals, upon which it
shall be practised; though it may be thought worth while for satisfaction
and certainty, to determine that point by Experiments. The case of
exchanging the bloud of Animals seems not like that of _Graffing_, where
the _Cyons_ turns the Sap of the _Stock_, graffed upon, into its nature;
the _Fibres_ of the Cyons so straining the juice, which passes from the
stem to it, as thereby to change it into that of the Cyons, whereas in this
transfusion there seems to be no such {358} Percolation of the bloud of
Animals, whereby that of the one should be changed into the nature of the
other.

3. The most probable use of this Experiment may be conjectured to be that
one Animal may live with the bloud of another; and consequently, that those
Animals, that want bloud, or have corrupt bloud, may be supplyed from other
with a sufficient quantity, and of such as is good, provided the
Transfusion be often repeated, by reason of the quick expence that is made
of the bloud.

_In the last _Transactions_ was also promised an Accompt by the next, of
Monsieur _Hevelius_ his accurate Calcul. of the late _Solar Eclipses_,
Duration, Quantity, &c. But this being to be accompanyed with _Scheme_, the
_Graving_ whereof met with a disappointment, it must be still referred to

_An Accompt of some Sanative-waters in _Herefordshire_._

This account was communicated by Dr. _B._ in these words.

There are two Springs in _Herefordshire_, whereof one is within a Bolt, or
at least Bow-shoot of the top of the near adjoyning loftie Hill of
_Malvern_, and at great distance from the Foot of the Hill; and hath had a
long and old fame for healing of eyes. When I was for some years molested
with Tetters on the back of one and sometimes of both my hands,
notwithstanding all endeavors of my very friendly and skilful Physitians I
had speedy healing from a neighbouring Spring of far less fame. Yet this
Spring healed very old and Ulcerous sores on the Legs of a poor Fellow,
which had been poyson'd by Irons in the Gaol, after other Chirurgery had
been hopeless. And by many tryals upon my hands, and the Te
