IV.—CHEMISTRY. 
Art. LXV.—On certain of the Mineral Waters of New Zealand. 
By W. Sxey, Analyst to the Geological Survey Department. 
[Read before the Wellington Philosophical Society, 12th January, 1878.) 
Ar the instance of Dr. Hector I take up the subject of this paper, but all I 
think necessary to do at present in this matter is to collate from our 
several museum and laboratory reports statements of all the analytical 
results which I have obtained upon these waters, and to compare them 
with those of the celebrated European waters which ours resemble, stating 
at the same time their therapeutie properties, either as deduced from their 
composition, or such as to my knowledge have actually been discovered 
by direct observation. 
The arrangement of these waters here will necessarily be a geographical 
one, for I find that to present them in anything like a chemical order, that 
is, classified according to their composition, would entail upon me a far 
greater expenditure of labour and time than I can well spare, as several 
compendious tables would in such case have to be re-cast,— in fact, 
completely broken up, owing to their arrangement being geographical, 
dominantly so at least. The task of presenting our mineral waters in 
chemical order I therefore leave for some future time, when the whole or 
the greater number of them shall have been analyzed. 
There is this to be said in favour of the geographical arrangement I 
propose, viz., that it will enable anyone to gather at a glance the nature 
of all the waters of any particular district which have been reported on by 
the Geological Survey Department. 
It will be observed that several of the analytical results I shall describe 
are very meagre, but I have decided to enter all that has been accomplished 
in the Colonial Laboratory upon these mineral waters, as a little informa- 
tion even regarding any water may be valuable, and suffice for one’s wants 
until opportunities occur for making it fuller. 
The following is a list of the localities whence the mineral waters 
described in this paper were obtained :—
