article of inquiry concern metal and mineral the three letter of the cross-row  touch the variation of metal into several shape body or nature the particular  whereof follow tincture turn to rust calcination sublimation precipitation  Amalgamatizing or turn into a soft body vitrification open or dissolve into  liquor Sproutings or branch or Arboresss induration and mollification make  tough or brittle volatility and fixation transmutation or Version for tincture  it be to be inquire how metal may be tinge through and through and with what  and into what colour as tinge silver Yellow tinge copper white and tinge read  green blue especial with keep the lustre item tincture of glass item tincture  of marble flint or other stone for turn into rust two thing be chief to be  inquire by what corrasives it be do and into what colour it turn as lead into  white which they call cerus iron into Yellow which they call crocus Martis  quicksilver into vermilion brass into green which they call verdigrease for  calcination how every metal be calcine and into what kind of body and what be  the exquisite way of calcination for sublimation to inquire the manner of  sublime and what metal endure sublime and what body the sublimate make for  precipitation likewise by what strong water every metal will precipitate and  with what Additaments and in what time and into what body so for amalgama what  metal will endure it what be the mean to do it and what be the manner of the  body for vitrification likewise what metal will endure it what be the mean to  do it into what colour it turn and further where the whole metal be turn into  glass and where the metal do but hang in the glassy part also what weight the  vitrify body bear compare with the Crude body also because vitrification be  account a kind of death of metal what vitrification will admit of turn back  again and what not for dissolution into liquor we be to inquire what be the  proper menstruum to dissolve any metal and in the negative what will touch  upon the one and not upon the other and what several menstrua will dissolve  any metal and which most exact item the process or motion of the dissolution  the manner of rise boil vapour more violent or more gentle cause much heat or  less item the quantity or charge that the strong water will bear and then give  over item the colour into which the liquor will turn above all it be to be  inquire whether there be any menstruum to dissolve any metal that be not fret  or corrode and open the body by sympathy and not by mordacity or violent  penetration for sprout or branch though it be a thing but transitory and a  kind of toy or pleasure yet there be a more serious use of it for that it  discover the delicate motion of spirit when they put forth and can get forth  like unto that which be in vegetable for induration or mollification it be to  be inquire what will make metal hard and hard and what will make they soft and  soft and this enquiry tend to two end first for use as to make iron soft by  the fire make it malleable second because induration be a degree towards  fixation and mollification towards volatility and therefore the enquiry of  they will give light towards the other for tough and brittle they be much of  the same kind but yet worthy of a enquiry apart especial to join hardness with  toughness as make glass malleable c and make Bldes strong to resist and pierce  and yet not easy to break for volatility and fixation it be a principal branch  to be inquire the utmost degree of fixation be that whereon no fire will work  nor strong water join with fire if there be any such fixation possible the  next be when fire simple will not work without strong water the next be by the  test the next be when it will endure fire not blow or such a strength of fire  the next be when it will not endure but yet be malleable the next be when it  be not malleable but yet be not fluent but stupefy so of volatility the utmost  degree be when it will fly away without return the next be when it will fly up  but with ease return the next be when it will fly upward over the helm by a  kind of Exufflation without vapour the next be when it will melt though not  rise the next be when it will soften though not melt of all these diligent  enquiry be to be make in several metal especial of the more extreme degree for  transmutation or Version if it be real and true it be the further part of be  and will be well distinguish from extraction from restitution and from  adulteration I hear much of turn iron into copper I hear also of the growth of  lead in weight which can be without a conversion of some body into lead but  whatsoever be of this kind and well express be diligent to be inquire and set  down
