The agreement of this value with that from the earlier work on the 

 chloride and nitrate is all that could be desired. It would seem of 

 little use to further extend the work on the chloride, but a thorough 

 study of the bromide is very desirable. It is hoped that this part of 

 the work will be completed shortly.
