SkEv.— On the Mineral Waters of New Zealand. 441 
Only two of these interesting waters have as yet been fully analyzed, 
they are Nos. (11) and (12) ; the former, from the Hot Springs of Tarawera, 
contains a considerable quantity of free hydrochloric acid, its principal 
constituent being sodic-chloride. 
The other water (No. 12) is from Parkes' Spring, Taupo, and is the 
most saline water of this series ; it contains, besides, much silica. 
Both waters are rich in iodine. 
Subjoined are the results of these analyses, stated in grains per gallon.

The carbonic acid in No. 12 is that which is in a combined form; there is, besides, a 
quantity of this acid in & free state 
It will be gathered from these results that the Tarawera water is dis- 
tinctly an aluminous one, that is, it contains alum in some quantity, and is 
fairly rich in iodine. It has but few representatives in Europe. One of. 
these is the Labassére (Hautes Pyrénées) which is drunk for bronchial and 
laryngeal catarrh. The strength of this water, however, is only about one 
third that of ours. 
The other water, that from Parkes' Spring, Taupo, is of very much the 
same character as that from the Waiwera Hot Springs, but is far richer in 
iodine ; it bears a great resemblance to the mineral water of Luhatschowitz, 
in Moravia, which is useful in chronic bronchial catarrh, especially if com- 
bined with serofulous complaints, and in congested liver and hemorrhoids 
arising from sedentary habits. 
The samples from the other springs have a examined so far that 
their general character has been ascertained. The results will be found in 
the table given on the next page, computed in grains per gallon. 
It should be stated that'all these samples of mineral waters gave 
evidence of the presence of sulphuretted hydrogen, but as they were 
enclosed in corked bottles, the quantity of this gas naturally existing in 
them could not be ascertained, organie matters, such as cork, being able
