No. (12). — From Arild-kapakaxm, 2 miles from Oliinemutu, a small 

 pool with a strong outflow, having a temperature of 160°. It deposits 

 sulphur, and is surrounded by a great number of other baths and mud 

 volcanoes. It is reported to have powerful curative properties. It was 

 colourless as received, with a heavy deposit of silica, and an acid reaction, 

 which was permanent at its boiling point.

No. (13). — Sulphur Bay Spring, on the edge of Lake Kotorua, formed 

 by innumerable small jets forced up through sand, having a disagreeable 

 odour, and a temperature from 90° to 100°. This bath is reported to have 

 a powerful action on the skin, owing no doubt to the large quantity of 

 sulphuric acid it contains. As received, it was colourless, with a slight 

 flaky sediment.
