RESULTS. 



The Atomic Weight of Iodine. Series V. AgI:AgBr. 



These two series of experiments confirm with considerable exactness the 

 higher value indicated by Series IV, and lead to the suspicion that owing to cer- 

 tain pecuHarities of silver iodide which have already been discussed, the values 

 furnished by the earlier syntheses of silver iodide are too low. Further evidence 

 was therefore sought in new experiments which had as their object the deter- 

 mination of the ratio of iodine to both silver and silver iodide. Agreement be- 

 tween the sum of the weights of the iodine and the silver and the weight of the 

 silver iodide would furnish important evidence as to the accuracy of the methods 

 involved.
