Note 39 — Chapter XIX
Reading edition
At the request of Professor Liversidge, of the Sydney University, I asked Dr Bromlow, of H.M.S. Sapphire, to take water from these springs for analysis. The following table gives the proportion of salts in a million parts of water, or milligrammes per litre:—
Silica, insoluble, 131.33
” soluble, 5.78
Alumina and traces of iron, 74.92
Chlorine, 4506.06
Calcium, 1428.84
Magnesium, 3.04
Potassium, 72.03
Sodium, 1298.28
Sulphuric acid, 219.29
Undetermined or loss, 73.34
From the foregoing it will be seen that the greater part of the salts in solution consists of the chlorides of calcium and sodium.
