No. (14), — From Ti Kute, the " Great SiDiing," 10^ miles from Oliine- 

 mutu, a pool three-quarters of an acre in extent, having a temperature 

 varying from 100° to 212° in various parts. It boils furiously, and dense 

 vohmies of steam are continually rising from it. The water is of a muddy 

 brown colour, and contains a large proportion of sulphuretted hydrogen, 

 and is reported to be wonderfully ef&cacious in cases of rheumatism and 

 cutaneous disease.
