Then change the receiver or else put on new liquor to repair the weakening of part of the menstruum & drive over what will come in white fumes a good part of which will settle in a liquor & [d] if the fire have been strong most if not all of the rest will ascend in a dry form but in much less quantity then before. Mix this with twice its weight of strong menstruum (supplyd new from time to time to make amends for the produced phlegm) & soe by some cohobations you may bring the [d] whole {sulphur} naturæ into a liquor which in balneo or sand you may dephlegm as you will or if you please you may by further abstraction [d] reduce it to an El. F. P. of our pinguedo which [d] you may afterwards marry with {mercury} & proceed therewith according to Paracelsus.
