" Class IV. Eesults of analysis of specimen No. 156-L. Water, six 

 bottles ; forwarded by T. B. G-illies ; locality. Hot Springs, near Mahurangi, 

 Auckland ; received, 24-th January, 1868 ; reported on, 25th February, 1868; 

 4 oz. of Avater 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.
