[Spain abounds with crystalline rocks of all kinds,a tnong which are included a vast variety of marbles ina Il conditions, from the finest statuary marble, to others^'Iiich are only adapted for building purposes. Theformer are chiefly metamorphic, and of doubtful age, and°ccur especially in the Sierra Nevada . The oolitic rocks,^hich are developed to a great extent in Old and NewPastille, and the cretaceous rocks of the northern districts°f Spain , yield large supplies of the more varied and lessperfectly crystalline varieties.—D. T. A.]

Seed and stone barilla.
[Barilla is prepared to some extent in the provinces ofYalencia and Murcia , from the Salsola sativa and theSalicornia , which are there cultivated for the purpose.On the salt marshes and littoral deposits on the south-west coast these plants are met with wild, and are thereused for the same purpose. Its commercial value de-pends on the per centage of alkali it contains.]

Stone barilla, or subcarbonate of soda, impure.
[It is a fact universally known, that on the southerncoast of Spain , in many of the regions adjacent to hershores, and in the Canary Islands , the “ Salsola soda”and other species of salts from whence the crystallizedcarbonate is derived, have been produced spontaneously,as at present, from time immemorial. But this branchof national industry has been seriously interfered withby the introduction into commerce of artificial alkalis.Yet the manufacturers of neighbouring countries inwhich natural kali abounds, continue, notwithstanding,to employ the Spanish product, in spite of its incon-testible disadvantages for the saponification of oils. TheSpanish collection comprises some natural alkalis ofAlicant, Murcia, Barcelona, Granada , tlio Canaries, &c.The price of these rough salts, in the mass, is not less than18 reals, or nearly 5 francs the quintal. The alkali ofMurcia and that of Barcelona fetch sometimes as muchas 11 francs the quintal.
Carbonated kali, in its natural state, is procured in theisland of Teneriffe , in an almost horizontal bed, at the baseof the Pic or Yolcano of Teida. It is extremely plentiful
