and other southern countries :*— thus more than doubling the extent of the work in respect
of letterpress and illustrations of species.
It remains for me to record my obligations to the unrivalled botanical artist, Mr. Fitch,
who has, with few exceptions, lithographed the whole o f the plates, and drawn the majority
of them. The accompanying microscopic analyses (amounting to upwards o f 4 ,5 0 0 ) have
been made partly by him, partly by myself, and partly by the distinguished Botanists who
have aided me in the Cryptogamic portions of the several Floras. I am especially indebted
to the Rev. M. J. Berkeley for the descriptions and analyses of all the F m g i; to Dr. Ilm-vey
for the descriptions of the Algce of the first series, as well as for the lithographs and analyses
of the species figured in the Tasmanian and New Zealand F lo ra s; to W. Wilson, Esq., for the
analyses and descriptions of most of the M u sc i; to the Rev. C. Babington and Mr. W.
Mitten, for the descriptions of the Lichens in these F lo ra s; and to Mr. Mitten for those of
the H ep á tica , and their illustrations, in the New Zealand and Tasmanian Floras.
I have also sincere pleasure in thanking Mr. Reeve for having, from the commencement,
guaranteed the publication of the whole series ; and for the spirited and liberal manner in
which he has co-operated with me throughout.

* Tlie grant made by the Treasury to aid in the publication of the Botany of the Antarctic Voyage was £10 0 0 ,
to be expended solely in the drawing and lithographing of 500 quarto coloured plates. These, with the descriptive
matter, have been given by the Author free of all cost, and of all share in the proceeds of the undertaking, to the
Publisher, who has thus been enabled to bring out the series at a very much more moderate price than any similar
work.
