D. Analysis by Prof. Liver sidge of the Sydney University of a 



sample of the water collected by Dr. Bromlow^ R.N., about 

 1879.2 



The specific gravity was 1-0064 at 60° F. The total solids in 

 solution were 5824 grains per gallon ; but when heated to a dull 

 red heat, the residue was 546'9 grains per gallon, the combined 

 water having been driven off. Iodine and bromine were carefully 

 sought for, but in vain. Four pints of the water were examined.

Looking at the general character of these thermal springs of 

 i Javu-savu we may quote the remarks of Prof Liversidge and Dr. 



* Islands of the Pacific, by H. Stonehewer Cooper, 1888 edition. 

 2 Journal Royal Society, New South Wales, 1880, vol. 14. Miss Gordon 

 ( umming in At Home in Fiji gives the same analysis but differently stated.
