5. The Waiwera Hot Springs. 
These springs, now deservedly in such repute, were sampled for the 
Laboratory here so far back as January 26th, 1878, by Mr. Hardy; and 
this sample (a) was about that time analyzed, that is partially so, the 
result being as — stated in grains per =— —

This water as received was clear, and with a slight alkaline reaction. 
Since this analysis was made quite a large supply of this water has been 
presented by His Excellency the Marquis of Normanby, and upon this 
(b) a full analysis has been made. It is considerably more saline, as will 
be seen, than the former sample, so much so that it manifests a distinctly 
saline taste when applied to the palate. In other respects, however, it 
possesses similar characters. 
"The quantity of fixed matter gum in a gallon of it is 219-495 grains,

This water is of the same kind as that from Puriri, in the same provin- 
cial district, but is only of about halfits strength. It compares most nearly 
with the famous continental waters of Vichy im France and Fachingen in 
Nassau, both of which are largely used medicinally. 
I find that Dr. J. Carey has given a testimonial to Mr. R. Graham, of 
Auckland, in favour of this water, which is to the following effect :—'* Having
