"At one spot, particularly, about 30 degrees, there were marked
indications of volcanic action, and several hollows resembling small
craters of extinct volcanoes, near one of which we found a small spring
of water, maintaining always a temperature of about 76 degrees Farenheit,
when the thermometer standing in water in the kegs stood at 52 degrees,
and in the atmosphere at 54 degrees.
"The accompanying sketch of the country from Mount Bryan northwards, will
probably explain its character better than any written description. The
altitudes marked at the different spots where they were observed, were
obtained by the temperature of boiling water, as observed by two
thermometers; but as they were not graduated with sufficient minuteness
for such purposes, the results can only be considered approximate."

In the above report it will be observed, that there are some apparent
discrepancies between my account and Captain Frome's. First, with respect
to the position of the south-east extremity of Lake Torrens. Captain
Frome states that he found that point thirty miles more to the east than
I had placed it in my chart. Now the only sketch of my course under
Flinders range, and that a rough one, which I furnished to the Colonial
Government, was sent from Port Lincoln, and is the same which was
subsequently published with other papers, relative to South Australia,
for the House of Commons, in 1843.
