In obtaining these data, I unfortunately exhausted my stock of this 
water. 
12. Water from spring on west side of Waikato River. 
A water from a hot spring near a lake on the west side of Waikato 
River, Auckland, contributed by Mr. Justice Gillies, 28rd September, 
1868, is clear, of a decided alkaline reaction, contains 47:04 grains of fixed 
matters to the gallon consisting principally of alkaline chlorides, the 
remainder being chiefly silicate and sulphate of lime with alkaline car- 
bonates. There was not sufficient of this sample to allow of a complete 
analysis of these fixed matters. 
The following is Captain Hutton’s description of this a It was 
about four miles from Lake Wangape in the Waikato. There were several hot 
springs close together, but this was the largest of them being fifteen yards 
long by five yards broad, and it was very deep ; the water was so hot that it 
was impossible to bear the hand in it for more than a second, and on one 
occasion when he was in company with others, having caught a pig for 
dinner, they fastened it with flax and threw it into the spring, and on taking 
it out it was perfectly scalded and they had no difficulty in scraping the 
hair off; the temperature of the spring was from 160° to 200° Fahr. at the 
very least. The water itself was almost tasteless; he had drunk it himself. 
He thought it was the carbonate of sodium which gave it an alkaline re- 
action. What its effects would be as a mineral spring he could not say; but 
it was easy of access ; was very prettily situated, and was not more than 50 
miles from Auckland, and he trusted that some day it would be called into 
use," * E 
18. Wallingford Mineral Water. : 
The first water which I have to notice, as coming.from the provin- 
cial district of Wellington, is one from Wallingford; contributed 15th 
June, 1866. As only a few ounces of it were at my disposal, I have only 
been able to determine its character and the proportion of the saline 
matter contained therein. It is faintly acid ; has a pure strong saline taste, : 
and is somewhat turbid from the presence of aluminous substances. The 
total quantity of fixed salts present in a gallon of it is 826 grains. They are 
mainly composed of alkaline and earthy chlorides. There are present also 
traces of certain bromides and iodides. 
Dr. Grace subsequently handed in a water from about the same locality 
as the above. The two are similar, but the former is the richer in iodine.-- 
14. Mineral Water of Pahua. 
a. This is from a spring on Mrs. Sutherland's run, and i is remarkable 
for the quantity of iodides and the comparative paucity of sulphates therein.
