CONCLUDING REMARKS. 
slate at the lower elevation. At the points of highest elevation 
from Mount Bryan northward, igneous rocks of basaltic charac- 
ter protruded from below, forming rugged and fantastic outlines. 
“At one spot, particularly, about 30°, there were marked indi- 
cations 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° 
Farenheit, when the thermometer standing in water in the kegs 
stood at 52°, and in the atmosphere at 54°. 
“ 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 fur- 
nished to the Colonial Government, was sent from 
Port Lincoln, and is the same which was subse- 
quently published with other papers, relative to 
South Australia, for the House of Commons, in
