"Class IV. Results of analysis of specimen No. 156-L. Water, six bottles; forwarded by T. B. Gillies; locality, Hot Springs, near Mahurangi, Auckland; received, 24th January, 1868; reported on, 25th February, 1868; 4 oz. of water from cold spring (A) yielded 1.85 grain, or per gallon 74. grains; ditto hot (B), 3.51 grains, or per gallon 140.4 grains; ditto hottest (C), 3.54 grains, or per gallon 141.6 grains. The analysis of the solid residue from A could not be completed for want of material.

"(C.) The composition of C appearing the same as B to a qualitative examination, it was not quantitatively analyzed.

"Results of analysis of specimen No. 252-L, forwarded by T. B. Gillies, from a hot spring near a lake on the west side of the Waikato River, received 23rd September, 1868:—

"Water: Character, clear; reaction is decidedly alkaline; contains 47.04 grains of fixed matter per gallon, consisting principally of alkaline chlorides, the remainder being chiefly silicates of lime and alkaline carbonates.

"The carbonaceous matters are very small in quantity.
