with their distinguishing peculiarities, which we conceive will 
prove of interest to the Society. We are indebted for much of this 
valuable information to Mr. Caley, who collected the greater part 
of the New Holland birds belonging to the Society; and who - 
kindly. allowed us to make use of his original notes on these 
birds, written during his residence in the colony. We have also 
to express a similar acknowledgement to Mr. Brown, who, in his 
general zeal for science, did not neglect the interests of zoology 
while devoting himself to the advancement of his favourite 
study. To his liberality the Society is indebted for many of 
its choicest treasures; and the kindness with which he has 
communicated his information respecting them enhances their 
value. 
Still we have to regret that we are but imperfectly acquainted 
with a considerable number of the more important forms in the 
collection, either as to their manners or their internal anatomy ; 
and that many of our observations on them must necessarily be 
founded on conjecture. Great imperfection may consequently 
be expected in our details. A favourable prospect, however, 
opens to us of having our deficiencies supplied on many of 
these points; but a prospect, which we scarcely know whether 
we should most rejoice in or lament. The removal of the late 
Secretary of this Society to an important official situation in the 
country whose ornithology we are about to investigate, encou- 
rages us to hope for much valuable assistance to our labours : 
while at the same time we cannot avoid regretting his temporary 
absence from a Society, which is bound to him by every tie of 
respect and gratitude. But the evils attendant on separation 
will be softened down on both sides by the continued intercourse 
which science thus fortunately holds out between us; and we 
shall be the less. estranged, in being still participators in his 
eminent zeal for our common pursuit. We hope we do not
