[Retrospective marginalia:]
Esprit de {vitriol} avec celuy de Vinaigre. (in Boyle hand)

Take of good vitrioll calcined to yellowness what quantity you please, and wett it throughly with strong spirit of <vinegar i>, and abstract the liquor which will be very flegmatique, ad siccitatem. Then without takeing the <matter> out of the retort poure on as much <fresh> Spirit as before which <in> distillation will come over flegmatique almost as at the first.

This doe in all about four times, and at last press the matter left dry after the last operation, with a strong fire in a sand furnace, and Reserve carefully the Spirit, <which will be of {vitriol} & very sulphureous.>

La meilleure voye pour faire aigril le vin. (in Boyle hand)

Fill halfe a dozen barrells with <W: (or other fermented> 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], 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, of Zahab which being mixt with four partes of the other ingredient was afterwards by the fire freed from it, and then was very well mixt with about three times its weight of <Orpiment>, 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>, (though nothing fell into the crucible) for when it was taken out it weighed <twoo> dramms and a halfe.

[Entry 8]
[Hand: R]

[Note: This workdiary has been bound in Boyle Papers vol. 25 with workdiaries 34 and 35. We have distinguished these three workdiaries on the basis of handwriting. This workdiary from the 1660s, written largely in Hand E, is on pp. 71-4, but is then interrupted by pages 75-86, in Frederick Slare's and Warr's hands, who did not work for Boyle during the same time as Hand E. These pages constitute Workdiary 35 from the 1680s. Workdiary 23 resumes on p. 87 to p. 94. Pp. 87-94, though, are badly damaged. There is a large tear and various smaller holes at the bottom of the folded foolscap sheet making up pp. 87-90 which render much of entries 28, 29, 35, 37, 38, 41, 48, 49, 50 illegible; much of the bottom of the folded foolscap sheet making up pp. 91-4 has been torn off rendering many of these entries illegible, if not completely missing (approximately the bottom fifth of pp. 93-4 is missing).]
