AFRICA AND ITS EXPLORATION. 
rature of 110° Fahr., except one on the extreme north, 
which was only 107° Fahr. 
I bottled eight ounces of water from one of these 
springs, and on arriving in London sent it to Messrs. 
Savory and Moore, the well-known chemists, 143 Bond 
Street, who in a few days kindly returned me the follow- 
ing analysis : — - 
“ The fluid was clear, colourless, and odourless ; on 
standing at rest, a small quantity of red granular 
matter was deposited. 
“ Examined chemically, it was found to have a faint 
alkaline reaction, and its specific gravity, corrected to 
60° F., was 1004, water being considered 1000. 
“ One hundred grammes evaporated left a white 
crystalline residue, weighing *37 of a gramme, and it 
was composed of sodium carbonate, calcium carbonate, 
calcium sulphate, and sodium chlorine ; this order repre- 
sents their proportions, sodium carbonate being the chief 
constituent, and the other salts existing in more minute 
quantities. 
“ The deposit was removed and examined micro- 
chemically : it was thus found to consist of ferruginous 
sand, and two minute pieces of vegetable cellulose. 
“ It was therefore a faintly alkaline water, and its 
alkalinity depended on the presence of sodium carbonate 
possibly existing in solution as bicarbonate, as the water 
held in solution carbonic acid gas, and this gas was 
evolved by heating the water.” 
The natives praised the water of these springs so 
highly that I resolved to stay three days to test in my 
own person what virtues it possessed. I drank an 
enormous quantity of the water with a zealous desire to 
be benefited, but I experienced no good — on the con- 
trary, much ill, for a few days afterwards I suffered 
from a violent attack of intermittent fever, occasioned, 
I fancy, by the malaria inhaled from the tepid atmo- 
sphere. It is true I luxuriated morning and evening 
in the bath which was reserved for me by Luajumba, 
son of Rumanika, but that was all the advantage that 
accrued to me.
