The formula requires 46-67 per cent (4n=54). The sulphate 
employed was pure and perfectly anhydrous. In two analyses 
of crystallized chlorid of manganese not quite free from mechan- 
ically mixed water, Mr. F. W. Clarke obtained 27:08 and 27-07 
per cent of manganese. In the same salt the percentage of 
chlorine was found to be 35°68 which corresponds to 27:14 per 
cent of manganese
