The most part of the oils that wee have touched on, heretofore, being adustible, are by consequent of a strong and troublesome odour, as smelling the burnt, when they burn, you must therefore set them in the Sun certain dayes, that is to say, to dry them in the Sun, and in the Air, to take away from them this fiery smell: for recompence we will here treat of some rare ones and of good agreeable odour. And in the first that of Been, which prefumers use, hath neither colour, odour, nor savour: and therefore it is susceptible of all those which you shall apply thereunto. Being repassed upon Sand to take away the fatnesse, it would bee of long durance, and without an ill sent, but it is too dear. As for oils of Olive, rapes or long turneps, _chenevy_, sesamum, but is rare in these quarters: and other the like which are drawn by the press, by means of the heat of fire: what repasses soever there may bee, yet they never desist to be of a good odour, but so much lesse, according as they shall bee depured and by the same means of longer durance: Oils of Sage, Thyme, Pepper and other the like, drawn by an instrument proper thereunto, such artifices, are so divulged even unto Chamber maids, that I should bee ashamed to speak of: That of Benzoine is more rare, and lesse known, and more laborious to make. Take Benzoin thoroughly beaten to grosse powder, and put it into a Cornue with fine _Aqua vitæ_, which swimmeth thereover three or four fingers, and leave them so for two or three daies upon a moderate fire of ashes, that the _Aqua vitæ_ may not distill, removing them every houre; this done, accommodate the _Cornue_ upon the furnace with an earthen vessell full of Sand. Distill the _Aqua vitæ_, with a gentle fire, afterwards increasing it by degrees, there will appear infinite little _aiguilles_ and filaments, such as in the dissolutions of lead and quicksilver. The which sheweth sufficiently that Benzoin participates thereof: It whitens Copper, quickens Gold, and put in decoction of _gayac_, doth admirable effects, as also Tartar, which containeth much quick-silver. When then these veins or little _aiguilles_ shall shew themselves, continue this degree of fire, and let them play within the Cornue a certain space, so long that all vanish away. In the interim have in a readinesse a little stick which may enter within the neck of the _Cornue_ for these _aiguilles_ will come thither to bring again as in an _mouelle_, and if you take them not away speedily the vessell will break when this Gumme or Mouelle shall bee all past, with a certain form of butter, which will cast it self afterwards within the Recipient, the oil will begin to distill fair and clear, of an hyacinth colour, and fragrant odour: after which reinforcing the fire, there will issue out another more thick and dark, which you must receive apart. This Gumme or white marrow, which you shall have drawn out of the neck of the Cornue, wash it with the _Aqua
