vl PREFACE TO VOL. V. 
came the earliest collections of Australian Algee which, through the kind- 
ness of Sir W. J. Hooker, fell under my notice; many new species are of 
his discovery; to him is also due the re-discovery of Claudea elegans ; 
and to him [ am not only indebted for the freest use of his personal col- 
lections, but for multitudes of duplicate specimens. 
During my residence at Georgetown, Tasmania, the Rev. J. Fereday 
rendered me the most efficient aid in prosecuting my researches. His 
boat and his strong arm were almost daily at my service, and many 
thousands of specimens were collected under his auspices. He knew all 
the best localities on the ‘Tamar, and was continually my guide to them. 
Without his able guidance and active assistance, my visit to Georgetown 
would have proved comparatively unfruitful, instead of yielding me a rich 
harvest of specimens. ‘lo Mrs. Fereday I am indebted for many beauti- 
fully preserved specimens, and for aid in “laying out” and drying the 
tubs-full of delicate Algee which we almost daily brought home. 
And now I must, in more general terms, return thanks to other cor- 
respondents and contributors. ‘To Henry Watts, Esq., Warnamboul; to 
S. Hannaford, Hsq., Geelong; to Mrs. Barker, Cape Shank; to William 
Archer, Hsq., Cheshunt; to Dr. Curdie, Geelong, and to — Raw- 
linson, Esq., Melbourne (through Dr. Mueller), I am indebted for many 
choice specimens. 
And lastly, though not least, | have to express my warm thanks to my 
friends George Bennett, Esq., M.D., Sydney; to Charles Moore, Hsq., of 
Sydney Botanic Gardens; and to Dr. Mueller, Melbourne, for their very 
active and kind exertions in making known this work in Australia, and in 
procuring subscribers to it. 
I speak not now particularly of personal attentions rendered to me 
during my sojourn in the Colonies, further than this, that I landed in 
Australia a stranger, and left its hospitable shores, after about a twelve- 
month of maritime excursions, having made many friends, and taking 
away with me very pleasant memories of its society.
