"ALKALI, in cliemistry ; from the 

 Arabian kali, the name of a plant from 

 the ashes of which one species of alkali 

 can be extracted. The true alkalies 

 have been arranged by a modern che- 

 mist in three classes: — 1, those which 

 consist of a metallic basis, combined 

 with oxygen ; these are three in num- 

 ber — potash, soda and lithia; 2, that 

 which contains no oxygen, viz., ammo- 

 nia ; 3, those containing oxygen, hydro- 

 gen and carbon ; in this class are placed 

 aconita, atropia, hrucia, cicutn, datura, 

 delphia, hyoscyamia, morphia, strych- 

 nia. And it is supposed that the vege- 

 table alkalies may be found to be as nu- 

 merous as the vegetable acids. The 

 original distribution of alkaline sub- 

 Btnnccs was into volatile and fixed, the 

 volatile alkali being known under the 



ashes of'vegetables gener:illy; the other, 

 \soda or mineral, on account of its hav- 

 ing been principally obtained from the 

 incineration ofmarine plants.'' — Encyc. 

 Am. The sulphate of ammonia has 

 been used with success as a stimulant to 

 vegetable growth — and is now prepared 

 and sold by chemists for that purpose.
