What this source establishes
Nothing — and that is the point. Every account of 1803 descends from this one printed book. It has never been digitised; four physical copies are known (Paris, Canberra, Toulouse, Shembaganur); and nobody working on this website has opened any of them. There is no page to show you here, and we would rather say so than show you a page we have not read.
Nobody here has opened this book. What it is cited for is written above, and no more than that is claimed.
