formation was to have been expected under these circumstances. 

 The authors also attempted to analyze the original mineral, but 

 two independent specimens obtained from the same dealer proved 

 to be chemically sodium chloride while their specific gravity was 

 only 2*16, that given for sulphohalite being 2*489. 



The authors conclude, on the grounds stated, that for the pur- 

 poses of their investigations they are not called upon to take such 

 a double salt as 3Na 2 S0 4 . 2NaCl into consideration. Further- 

 more, they add that " the existence of sulphohalite appears at 

 least doubtful," a conclusion which hardly seems justified.* —
