cies, which grows on the French Mediterranean coast, is much 
used in Languedoc for the preparation of this salt, which is usually 
exported to Sicily and Italy. 
Salsola Tragus, Zin. affords an ordinary kind of Soda, with 
which the French frequently mix that made in Languedoc: this 
adulteration is also practised by the Sicilians, who distinguish the 
plant by the term selvaggia.*

over Europe. Linnzus prefers the Soda obtained from this plant 
to that of all the others;' but though the quantity of fossile alkali 
which it yields is very considerable, as a great portion of it is 
united with muriatic acid, it is mixed with much common salt.

this alkali. It has also been procured from several of the Fuci,

_. yielding Barilla or Soda-by combustion ;+ but the principal are 
confined to the genus Salsola and that of Salicorttia-—The Salsola 
Kali, on the authority of Rauwolf, is the species from which the 
salt is usually obtained in eastern countries.*

t To these we may add Batis maritima, (Vide Jacquin Hist. Stirp. Amer. p- 
127.) which on the coast of Carthagena is found to have a very salt taste, where 
it is prepared into soda, which is used for the purpose of making glass. The 
Carthaginians call this plant baré/a.
