From these results it appears that, at 100° and higher tem- 

 peratures, hydrous aluminum bromide loses water and hydro- 

 gen bromide simultaneously, both in air and in an atmosphere 

 of hydrogen bromide ; but that the loss of water, as well as 

 of hydrogen bromide, from the salt is retarded by the atmos- 

 phere of hydrogen bromide. At the highest temperature 

 recorded, 210° C. the salt still retained bromine. There is 

 nothing to indicate that any part of the water possesses a dif- 

 ferent relation to the salt from that possessed by any other 

 part of the water. 



Discussion of Results. 



In correlating the phenomena noted, Cushman's hypothesis 

 of inner and outer linkages of water relative to the molecular 

 complex, upon the assumption of quadrivalent oxygen, seems 

 applicable.
