 gen bromide when the salt is heated in air increases generally 

 with the temperature and is inhibited, as is the loss of water,

by the atmosphere of hydrogen bromide. It appears that 

 about a third of the water of magnesium bromide bears a 

 relation to the salt different from that of the remainder.
