that of chloride of sodium, it is less soluble in alcohol than 
in water; exposed to the air it is not altered, but its mother- 
ley acquires under the same conditions a yellowish tint. 
Achilleate of soda is prepared with carbonate of soda in 
the same manner as the potassa salt. The taste of this salt 
very much resembles that of the preceding, as also its solu- 
bility in water and alcohol, but its crystalline form is very 
distinct from that of the potassa salt ; a clear concentrated 
aqueous solution yielded very beautiful rhombic crystals, 
which could be perceived with the naked eye. 
Achilleate of ammonia maybe prepared by mixing achil- 
le'ic acid with ammonia; the liquid becomes pale yellow 
when evaporated to a syrup. By exposure to the air for 
several days it slowly evaporates to a saline mass, which 
has a similar taste to the potassa and soda salts. It is solu- 
ble in water and insoluble in pure alcohol. 
Achilleate of lime crystallises in irregular scales or needles: 
it is obtained when lime is treated for some hours with 
slightly diluted achille'ic acid, filtered and set apart to crys- 
tallize; it is insoluble in absolute alcohol. 
Achilleate of magnesia is difficult to obtain in the crys- 
talline form; when its solution is allowed to evaporate in 
the air, a yellowish, solid, transparent, gummy mass, more 
soluble in water than in alcohol, is obtained. It is prepared 
in the same way as the salt of lime. 
Achilleate of quinine. — Quinine dissolves in slightly di- 
luted achille'ic acid by allowing the substances to act for 
several days on each other, stirring them frequently until 
the liquid no longer reddens litmus-paper. Upon this it is 
filtered, and some alcohol added ; it is heated nearly to 
boiling, and allowed to cool. Nearly the whole liquid is 
converted into very beautiful radiate-grouped prismatic 
crystals. The salt has a very bitter taste, and is readily 
soluble in water and alcohol. On account of its great solu. 
bility, the author considers that it will be found better 
adapted than sulphate of quinine for medical purposes. —
