[B, 
some idea of the Flora of its shores and neighbouring 
country, from which I gathered materials for comparison 
with the vegetation of Endeavour River, situated at the 
eastern extreme of its parallel on the opposite shore of the 
continent : the identity of certain species on either coast, 
together with the inference drawn therefrom, will appear 
stated, towards the close of this general notice. Very few 
new genera were the fruits of this third voyage, but many 
undescribed plants of old genera were discovered, and with 
those that are frequent on the North Coast, and tropical 
shores of New South Wales, some were remarked that were 
originally discovered on the South Coast. The period again 
arrived, that rendered it necessary to depart from the coast, 
independent of the leaky state of our vessel, which mate- 
rially hastened our return to Port Jackson, when the cutter 
was considered wholly unfit for a fourth voyage, in which 
the complete survey of the north-west, and the examination 
of the line of west coasts were contemplated. To effect this 
important service, the colonial government purchased a brig, 
subsequently named the Bathurst, and I again accompanied 
Captain King from Port Jackson, in May, 1821, to those 
parts of the coasts then remaining unexplored, at which we 
arrived at the close of July. Our very limited stay on those 
shores, however, was at that season wherein all vegetation 
was suffering under the excess of drought; I had never- 
theless the means afforded me of ascertaining the general 
identity of the plants of Prince Regenffs River, Hanover Bay# 
and Port George the Fourth, (portions of the coast explored 
in the voyage) and other parts in the vicinity, that were ex- 
amined the preceding year, at a like season, but under cir- 
cumstances much more favourable. Upon ourre turn to the 
North-west Coast from the Mauritius, early in 1822, the 
only part visited was Cygnet Bay, situate about 2-J° to
