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.

This sketch was put together hastily for his Excellency the Governor, that I might not lose the opportunity of forwarding it when I sent from Port Lincoln to Adelaide for supplies early in October, 1840.

It was constructed entirely, after I found myself compelled to return from the northern interior, and could only be attended to, in a hurried and imperfect manner, during the brief intervals I could snatch from other duties, whilst travelling back from the north to Port Lincoln (nearly 400 miles,) during which time my movements were very rapid, and many arrangements, consequent upon dividing my party at Baxter's range, had to be attended to; added to this were the difficulties and embarrassments of conducting myself one division of the party to Port Lincoln, through 200 miles of a desert country which had never been explored before, and which, from its arid and sterile character, presented impediments of no ordinary kind.
Upon my return to Adelaide in 1841, after the Expedition had terminated, other duties engrossed my time, and it was only after the publication of Captain Frome's report, that my attention was again called to the subject.
