8. When it is perfectly united with phlo- 

 giftic fubftances belonging to the ve- 

 getable kingdom, and the water has 

 been perfectly feparated, this mixture 

 catches flame in the open air, and is 

 confumed, as may be feen by the powder 

 called Pulvis pyrophorus. 



9. It attracts water ftrongly, and the 

 aqueous vapours out of the air : and if 

 a great quantity of water is added to it 

 at once, a ftrong heat arifes. 



10. It unites readily and eafily with the 

 alcalis, whereby, according to their na- 

 ture, different compounds are produced, 

 which have obtained the names of Tar- 

 tarus vitriolatus^ fal mirabtle y and/*?/ am- 

 moniacum fixum.
