noticed as yielding Barilla or Soda by combuftion ;J but the prin- 
cipal are confined to the genus Salfola and that of Salicornia. The 
Salfola Kali, on the authority of Rauwolf, is the fpecies from whicl 
the fait is ufually obtained in eaflern 
It is to be regretted, that the different kinds of Soda which are 
brought to European markets, have not been fufficiently analyfed 
to enable us to afcertain with tolerable certainty the refpeclive 
value of each ; and indeed while the practice of adulterating this fait 
continues, any attempts of this kind are likely to prove fruitlels : 
the beft information on this fubjecl: is. to be had from Turn

Marcorelle, 1 Cadet, Borlafe, 1 and Seftini. m In thofe places where 
the preparation of Soda forms a confiderable branch of commerce, as 
on the coaft of the Mediterranean, feeds of the Salfola are regularly 
fown in a proper fituation near the fea, n which ufually moot above 
ground in the courfe of a fortnight. About the time the feeds becom 
ipe, the plants are pulled up by the roots, and expofed in a fuitable 
to dry, where their feeds are colleded : this being done, the 
plants are tied up in bundles, and burned in an oven conftruaed for 
the purpofe, where the afhes are then while hot continually flirred 
with long poles. The faline matter, on becoming cold, forms a hard
