NITRAT OF LIME. 



THIS saline substance is found in the rubbish of old 

 buildings, and in those materials from which salt-petre 

 is extradted : viz. animal and vegetable matters, which, 

 with a due proportion of calcareous earth, have under- 

 gone the putrefactive process, together with a subse- 

 quent, sufficiently long, exposure to atmospheric air. 

 According to Dr. HOME, it is likewise contained in what 

 is commonly called hard water, which, by his experi- 

 ments, was found to promote the growth of plants in 

 a much higher degree than soft- water. 



Nitrat of lime is very soluble, and is deliquescent; it 

 is decomposed by fixed alkalis, and forms therewith 

 nitrat of potash or salt-petre, and nitrat of soda, or cu- 

 bic nitre.
