Skey. — 0)1 the Mineral Waters nf Neic Zealand. 



441 



Only two of tliese interesting waters have as yet been fully analyzed, 

 tliey are Nos. (11) and (12) ; the former, from the Hot Sin-ings 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 tlie 

 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 a 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 Labassere (Hautes Pyrenees) 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' Sx^ring, 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 scrofulous complaints, and in congested liver 'and hemorrhoids 

 arising from sedentary habits. 



The samples from the other springs have been 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 i^resence of sulphuretted hydrogen, but as they were 

 enclosed in corked bottles, the quantity of this gas naturally existing in 

 them could not be ascertained, organic matters, such as cork, being able
