RemArks.—The residue from this water gave no reaction for 
nitrates ; it contains a little sulphate of calcium in solution ; but 
the major part of the solids are present chiefly as chlorides of 
sodium, potassium and magnesia. The smallness of the sample 
(about 4 litre) precluded a more detailed examination, but enough 
had been done to show that it was a fair water. Poisonous metals 
were not detected.

sumption.
