MINERAL WATERS OF AUSTRALASIA. 93 
Pahua, Wairarapa E.—W. Skey. Transactions, New Zealand 
Institute, vol. x, p. 444; XIIth Colonial Museum and 
Laboratory Report, p. 45. 
Chlorinated saline water, containing free iodine ; reaction 
distinctly alkaline.—Total solids, 1,474-09 grs. per gal. ; sodium 
chloride, 1,305°32 ; potassium chloride, ‘50 ; magnesium chloride, 
34:96 ; calcium chloride, 120-88 ; magnesium iodide, -58 ; mag- 
nesium bromide, traces ; calcium sulphate, 3:02 ; aluminium 
phosphate, *64; calcium phosphate ; -43 ; calcium bi-carbonate, 
6°45 ; silica, 1-69 ; iodine free, 1°59. A very characteristic water 
from the amount of free iodine it contains. 
Pakaututu, Napier.—W. Skey. XXIXth Colonial Museum and 
Laboratory Report, p. 19. 
Two waters, containing respectively 20°12 and 14:3 grs. per 
gal. of sodium chloride, with sulphuretted hydrogen and iodine in 
sensible quantities. 
Papawhaniki, near Gisborne.—W. Skey. XXIVth Colonial 
Museum and Laboratory Report, p. 41. 
A chlorinated saline water, feeble alkaline reaction. 
Total solids, 764:5 grs. per gal., principally sodium chloride ; 
iodine, 3°69 grs. per gal. 
Puriri, Hikutaia, Auckland.—W. Skey. Transactions, New Zea- 
land Institute, vol. x, p. 425. XVth Colonial Museum and 
Laboratory Report, p. 45. 
Alkaline water.—Specific gravity, 1-006; total solids, 537-11 
grs. per gal.; sodium chloride, 21:93; sodium sulphate, -94 ; 
potassium sulphate, 4:93; calcium bi-carbonate, 28-50 ; magnesium 
bi-carbonate, 25°62; sodium bi-carbonate, 452°39; silica, 2°77. 
Traces of magnesium iodide, ferrous carbonate, and lithia. 
This water is highly sxrated with carbonic acid, and effervesces 
strongly when escaping from the spring. 
A second analysis, 1880, showed but little change in the nature 
of the salts present, but that the water had become more concen- 
trated. Total solids, 825-10 grs. per gal. 
Rotorua District.—J. Hector. New Zealand Official Year Book, 
1896, p. 429. <A. Ginders, zbid., p. 433, 
See analyses, p. 100.
