 the temperature increases to 180°, with a strong outflow. Thick masses of 

 shmy Confer void plants Hne the bottom of the pool. As received, the water 

 was clear and colourless, with an alkaline reaction.

Excess of silica over what is required to pass these bases as mono-silicates is 5-55. 



Xo. (8) — From Turi-kore or Whakarewarewa, 2f miles from Ohine- 

 mutu. The sample was taken from a waterfall which drains from a large

Xo. (4) — From Kuirua, in the native village of Ohinemutu, on the shore
