LITHIUM BROMIDE. 



The lithium bromide used in this work was obtained from Kahlbaum. No 

 appreciable impurity could be detected. It was dried in an air-bath at 159, 

 after which it was kept in a desiccator. Whenever the salt was exposed to 

 the air, the operation of drying to constant weight was repeated.
