which are to be put into a Qiiart of Olive Oil* 

 and boiled till they are criip, and the Oil is to' 

 'be then ftrained off. 



3* What is called the Green Oil, is thus maae, 

 bruife in a marble Mortar, three Ounces of green 

 Chamomile, with the fame Quantity of Bay 

 !Lea\?es, Sea Wormwood^ Rue, and Sweet Mar- 

 joram ; then boil theni in a Quart of Oil of 

 Olives, till they are a little crilp. The Oil is 



then to be poured off, and when cold put up for 

 Ufe. 



Thefe Oils are ufed to rub the Limbs when 

 there is Pain and Swellings ; their Virtues will be 

 found at large, under the feveral Herbs which 

 are the principal Ingredients : And after one or 

 other of thefe Methods, may be rnade the Oil 

 by Infufion, or . by boiling of any Plant, or of 

 any Number of Plants of like Virtue; ' . ; 



Laftly, tho' Herbs are now left out of the Com- 

 pofition of Plaiflers, even the Melelot being now 

 made without the Herb from which it was firfl. 

 named : It may be proper to add the Way of 



preparing a few that are mofl: ufeful, and ought 

 to be kept in Families. 



I. The Common Plaifter is thus made; boil 

 together a Gallon of Oil, five Pounds of powder- 

 ed Litharge, and a Quart and four Ounces of 

 Water. When the Vfater is boiled away, the 

 reft will be united into a Plaifter, but it nmft be 

 ffirred all the Time : This ufcd to be called Dia- 

 chylon. To 'make Diachylon with the Gums, add 

 to a Pound of the laff defcribed, two Ounces of 

 Galbanum, and an Ounce of common Turpentine", 

 and the fam.e Quantity of Frankincenfe. Melt 

 them all together, the Gums firff, and then add
