from Marseilles: 12 bottles in a basket.— Both these olive oils 

 are used with salads, and for frying, also to soften the hair, and 

 to anoint the body all over as a preservative from the plague. 

 They become concrete when poured upon a solution of 6 drachms 

 of quicksilver in 7 drachms of nitric acid at S8 deg. Baume.

 to sweat. Its quality is estimated by the quantity of foot or lees 

 that separates on standing, the less the better ; used for plaisters 

 and ointments, the lamp, as it yields scarcely any soot, and largely
