[Integral marginalia:]
Jan. 10

Make with Sublimat and Kursella a thick oil like that made the common way with {antimony}, poure upon this <pure> Sp. of wine till it swim 3 or 4 fingers above it, digest it for some dayes, and then destill them off [ 'for' deleted] by degrees with a heedfull care, and imploy the acidulous <(not corrosive)> menstruum upon Coralls &c.

To one part of calcin'd English Talck add 2 (or one) of Tacola, melt this fusible mixture with Durca and though they will not incorporate the Durca will be much wash'd and innobled thereby.

Take the white stone that Paracelsus commends so much <(I.E. white Pebbles>[in pencil ] reduce them without calcination to fine pouder, put this in to an iron or other strong Cucurbit in a stoopeing posture, Let the head be of glass, give a very strong fire and dephlegm well what comes over < tis to make a spirit of [R?oals.][unclear]>[insertion in line in unidentified hand]

Take kursella very exquisitly calcined, and melt about 2 parts of it with one of Durca they will not well incorporate together, but yet the colour will be much improved, without makeing the body immalleable. < tis to make a new metal well coulered and not britle.>[insertion in line in unidentified hand]

Take very well calcind kursella, calcine it by casting in by degrees about thrice its weight of good Nitre, then mix with it a pritty quantity of pouder'd charcoal to facilitate the fusion, (which [ 'twill hardly be' deleted] 'twill be difficult and not absolutly necessary[altered from 'necessira'] to make perfect) after which you may take the reduc'd body and proceed with it as if it were Quatrum, [ 'by the' deleted] according to the same manner you may handle Vinetum Paracelsi. < tis to cople tin and Zinck.>[insertion in line in unidentified hand]

If you mix Tura or a little Cursella with Barakid you may with Ormum somewhat reduce it, but the best way is to keepe it an hour or better in a strong heat with 3 or 4 times its [approximately 3 characters tear in page] heat of good Dakilla well made and preser[approximately 3 characters tear in page] from the Air < to reduce Lune.>[insertion in line in unidentified hand]
