LIG:f^ITE JAYET. 



1. Turf and Peat. Characterised by the pre- 

 sence of Ulmic Acid, and also by the woody 

 fibres or the cellules of the medullary rays, 

 which may be purified and extracted in 

 notable quantity by means of nitric acid or 

 hypochlorites, in which they are insoluble. 



2. Fossil Wood, or Woody Lignite. This, 

 like the preceding, is partially soluble in 

 alkalies, but its alteration is more advanced, 

 for it is nearly wholly dissolved by nitric 

 acid and hypochlorites. 



3. Compact, or Perfect Lignite. This sub- 

 stance is characterised by its complete solu- 

 bility in hypochlorites and in nitric acid. 

 Alkaline sofutions do not in general act on 

 perfect Lignite. Reagents in this variety 

 show a passage of the orsranic matter into 

 Coal. 



4. Coal. Insoluble in alkaline solutions 

 and hypochlorites. 



b.' Anthracite. An approximation to Gra- 

 phite, resists the reagents which act on the 

 above-mentioned combustibles, and is only 

 acted on by nitric acid with extreme slow- 

 ness.

Rolled masses of Lignite were formerly 

 found on the shore at Brighton, in such 

 abundance as to be used for fuel by the 

 poorer classes, but its use was prohibited 

 on account of the very offensive odour it 

 gave out during combustion. 



It was employed by Dr. Russell as a fu- 

 migation in certain glandular complaints, 

 and it is said with decided benefit. 



The provincial name {Strombolo') by 

 which it was known is a corruption of 

 Strom-boJlen, stream or tide-balls, as they 

 were called by the Flemings, who formerly 

 settled in Brighton. (3Iantell.) 



Lignite Jayet. French for Jet. 



LiGURE. The stone mentioned under 

 this name in Exodus xxviii. 19 was pro- 

 bably the Jacinth or Hyacinth. It occupied 

 the seventh place among the stones ordered 

 to be set in the breast- plate of the Jewish 

 high-priest, and was engraved with the 

 name of the tribe of Gad. See Hya- 

 cinth.

 speckled externally. Colour apple-green.

 parency.
