T he third volume of my log book and journal having been lost in 
the events which succeeded the decay of the Investigator, I have had 
recourse to a memorandum book and to officers journals to supply 
the dates and leading facts contained in the first three chapters fol- 
lowing; fortunately, my bearings and the astronomical observations 
taken by lieutenant Flinders and myself were preserved, as also were 
the rough charts, with one exception ; so that there are few cases 
where this department of the voyage will have materially suffered. 
There are, however, many circumstances related in these chapters, 
which either do not enter at all, or are slightly mentioned in the 
officers journals ; for these, my public papers and copies of letters 
have principally furnished materials, and a tolerably faithful memory 
lias supplied the rest. It seemed necessary to explain this, that the 
reader may know to what the deficiencies and abridgments in some 
1803.
