CALCIUM NITRATE. 



It was thought that the study of a ternary salt might prove interesting. 

 Jones and Lindsay had already made a study of strontium iodide, and had 

 found it to exhibit the same phenomena as did binary salts. 



The calcium nitrate used was a preparation obtained from Kahlbaum. 

 This substance was found to be particularly difficult to dehydrate. Heating 

 for several days to a temperature of 103 to 140 was necessary to bring it to 

 constant weight. This treatment caused no perceptible decomposition. All 

 the original solutions were made by direct weighing.
