 Melts and deflagrates on hot charcoal. 

 Rather sectile. Fracture imperfect-con- 

 choidal. H. 1-5 to 2. S.G. 2-1 to 2-2. 



Comp. Nitrate of soda, or Na Ni = 

 soda 36-6, nitric acid 63 4 = 100. 



BB fuses when heated, and on cooling 

 solidities in a white mass. 



Locality. The pampa of Tarapaca on the 

 borders of Chili and Peru. The dry plain 

 is covered with a bed of this salt, to a depth, 

 of several feet, over an extent of forty 

 leagues. 



The deposits of nitrate of soda in Peru are 

 described by David Forbes as being explored 

 from the river of Pisagua, southward to 

 Patillos, in Bolivia, a distance of about 

 110 miles; but, latterly, new and exten- 

 sive deposits have also been woi-ked fur- 

 ther south, inland from Tocopilla. These 

 deposits, situated at about 2500 to 3500 feet 

 above the present sea-level, appear to run 

 from latitude 19° southward into the 

 northern part of the Desert of Atacama, 

 showing themselves, according to the con- 

 figuration of the country, at distances 

 varying from ten to forty miles inland.* 

 (^David Forbes.) 



It is used in the arts as a substitute for 

 nitre ; but in consequence of its deliques- 

 cence it has not been largely used for 

 making gunpowder.

 Colour greenish and yellowish-white." Lus-

 Brittle. H. 2. S.G. 1-9. 



Comp. Nitrate of potash, or K N = 

 potash 46'64, nitric acid 53-36 = 100. 



Deflagrates on hot coals, and detonates in 

 the fire with charcoal and other combus- 

 tible bodies. Readily soluble in water, pro- 

 ducing great cold. 



Localities. Spain, Egypt, Persia, Ai'abia, 

 India, South America, and many places 

 where organic matter has been decomposed, 

 especially in hot climates. Also covering 

 the bottoms of caverns in the United States. 



Name. From Nitria, the name of a city 

 in Upper Egypt, in the neighbourhood of 

 which this salt is found in considerable 

 quantities.
