{vitriol} avec celuy de Vinaigre. (in Boyle hand)
Take of good vitrioll calcined to
yellowness['y' altered from 'a'] what
quantity you please, and wett it throughly with strong spirit of
<vinegar i>[replacing '???e ??rd'], and abstract the liquor which will be very flegmatique, ad
siccitatem. Then without takeing the
<matter> out of the
retort['e' at end of word deleted]
poure on as much
<fresh> Spirit as before which
<in> distillation will come over flegmatique almost as at
the first.

La
meilleure voye pour faire aigril le vin. (in Boyle hand)
Fill halfe a dozen barrells with
<W: (or other fermented>[in Boyle hand] lyquor) soe
that one third may remaine empty and each of the Barrells may have a pretty
large hole to stand still open in the upper
<parte>, these vessells being kept in a [stove][unclear], or some such warme place for some dayes, a pretty
quantity of liquor is by the tapp to be taken out of the first and without
stiring the vessells to be putt into the second, and some out of that into the
third, and soe onwards, this must bee done from time to time with some
intervall, for the space of about sixe weekes, within which time the operation
may be compleated.

An od
Experiment about the weight of Zahab. (in Boyle hand)
There was taken a
dramm['e' at end of word deleted], of
Zahab which being mixt with four partes of the other ingredient was afterwards
by the fire
[ 'fire' deleted] freed from it, and then was very well mixt with about
three times its weight of
<Orpiment>[replacing 'the Roman Emperours' Minerall', Boyle hand], from which being alsoe freed there remained a dramm and a halfe
of fine powder which being putt per se in a crucible under a muffle and kept in
a strong heat for two houres instead of looseing in weight encreased a full
<Drachm>[replacing 'graine', Boyle hand], (though nothing fell into the crucible) for when it was taken out
it weighed
<twoo>[in Boyle hand] dramms and a halfe.
[ 'and a graine more' deleted]
