' Take yellow Wax melted in a' little Canary Wine, ft i. Oil of' Olives, Venice Turpentine wafh'd« in Rofe Water, ana It ifs. Boil« them till the Wine is evaporated,' and when almoft cold, ftir in of' red Sanders finely powdered, § it.1 and piefcrve it for ufe."

This was very unskilfully directed ;

and lofe the better part of the Flow- for the melting the Wax in Canary

ers,and give an Empyremna, where-as Infolation alone will beft drawout and communicate their Effica-cies to the Oil, and preferve theirnatural Scent therein. But Oils,which have frequently the greenLeaves of Plants committed to themto draw the Virtues therefrom,ftand in need of boiling; the ufualStandard of which is, until the In-gredients grow crifpy. And herean Empireuma is carefully to beavoided, and alfo care to be takenthat the whole aqueous Part of theHerbs be evaporated ; for till thenit will not come up to its true Colour,but will be dingy, or have a yel-lowifh hue. The beft way there-fore to procure a fine green Colourto Medicines of this kind and raife'em to their greateft height,and at thefame time to avoid an Empyreuma,which befides the Stink would alfoturn it black, is to ftrain out the Oil,and afterwards pouring it into aclean Pan, let it ftand over a gentleFire, until by frequent Trials upona white Tile, it arrives to a high un-mixed Green ; for this way the Co-lour will very much heighten,beyondwhat it was when firft drained fromthe Ingredients. This Managementalfo quite driving away all aqueousParticles, it will keep much the Ion-

can anfwer no End, unlefs to fuchwhofe Opinions of a Medicine arein proportion to the trouble of mak-ing it ; nor does the warning theTurpentine with Rofe-Water availany thing. If therefore the Mate-rials are all good in their kind, asfoon as the Wax and Turpentine aremelted, let the Sanders be ftirr'd inwithout any boiling at all. But e-ven this way, which the Shops areoblig'd to comply with, becaufe thePhyfician would not elie know whathe prefcribes, the Sanders is a veryinjudicious Ingredient ; for it can-not anfwer any End as a Balfamic,neither in internal nor external Ufe jand if it be put in for the Colour-fake only, this might be much bet-ter done by boiling Dragons Bloodfor fome time in the Oil, with a fuf-ficient quantity of Water to keep itfrom burning : for with that it mightbe brought up to any degree of Co-lour and to a much more elegant Redthan the Sanders will give. Andwhen the Oil is tinged, ftrain itoff, mix the Wax and Turpentinewith it, and all is finifhed ; andthis way it is made in fome of ourHofpitals. By this means theMedicine is not clogg'd with Duftto give it a Colour, and is thereforemuch better for all the purpofes itI i 4. feerns
