J 54 ACTION OF SALTS ON VOLATILE OILS. 



General re- General conclusions. 



Fi^m the experiments above related it follows: 

 Effects of ace- !• That the oils of thA'me, lavender, rosemary, sage, and 

 tate of lead, or lemons, undergo no alteration, even by standing, with solu- 



' tion of acetate of lead, or of alum, 



ef muriate of 2. That the oil of the vulnerary plants with a solution of 

 limej muriate of lime, loses its lemon yellow colour, and becomes 



whiter. 

 «.f hyperoxi. 3. That the solution of superoxigenized muriate of potash 

 miiriateof pot- occasions no change in the oils of thyme, lavender, pepper- 

 mint, lemons, or cloves, 

 of lime water; 4. That lime-water destroys in part the colour of oil of 



rosemary, 

 of nitrate of 5. That nitrate of mercury is decomposed in oil of rose- 



mercury, mary, which it renders high coloured. 



of corrosive 6. That conosive sublimate, and its solution in distilled 



sublimate; water, increase the colour and consistency of the oils of le- 

 mons, chervil, h}ssop, lavender, and rosemary, and are 

 partly decomposed by them, producing mild muriate of 

 mercury. 

 of calomel and 7. That mild muriate of mercury and factitious cinnabar 

 esnnabar j occasion neither action nor i-eaction with oils of lavender and 



rosemary. 

 of tvirbith mi- ^' That turbith mineral is partly decomposed in oil of 

 ^"^•■3l ; rosemary. 



of rod precipi- 9* That red precipitated mercury is in part converted into 

 ^^^^'f g^'ay oxide in oil of lavender, without causing the oil to un- 



dergo the least alteration, 

 of muriate of 10. That caustic muriate of antimony is decomposed in 

 autmiony; oil of rosemary, which it colours and thickens; while part 

 of this muriate loses its acid, and appears to be converted 

 into silvery flowers of antimony, 

 of sugar; H. That an oleosaccharum is a more or less perfect com- 



bination, according to the oil emplo3'ed. 

 and of water. 12. Finally, that volatile oils shaken in distilled water 

 produce no heat, that is sensible to the thermometer, unless 

 they have been adulterated with spirit of wine.
