TO
CHARLES LYELL, ESQ., F.R.S.,

This second edition is dedicated with grateful pleasure, as an
acknowledgment that the chief part of whatever scientific merit
this journal and the other works of the author may possess, has
been derived from studying the well-known and admirable

PRINCIPLES OF GEOLOGY.



PREFATORY NOTICE TO THE ILLUSTRATED EDITION.

This work was described, on its first appearance, by a writer in
the "Quarterly Review" as "One of the most interesting narratives
of voyaging that it has fallen to our lot to take up, and one which
must always occupy a distinguished place in the history of
scientific navigation."

This prophecy has been amply verified by experience; the
extraordinary minuteness and accuracy of Mr. Darwin's observations,
combined with the charm and simplicity of his descriptions, have
ensured the popularity of this book with all classes of
readers--and that popularity has even increased in recent years. No
attempt, however, has hitherto been made to produce an illustrated
edition of this valuable work: numberless places and objects are
mentioned and described, but the difficulty of obtaining authentic
and original representations of them drawn for the purpose has
never been overcome until now.

Most of the views given in this work are from sketches made on the
spot by Mr. Pritchett, with Mr. Darwin's book by his side.  Some
few of the others are taken from engravings which Mr. Darwin had
himself selected for their interest as illustrating his voyage, and
which have been kindly lent by his son.

Mr. Pritchett's name is well known in connection with the voyages
of the "Sunbeam" and "Wanderer," and it is believed that the
illustrations, which have been chosen and verified with the utmost
care and pains, will greatly add to the value and interest of the
"VOYAGE OF A NATURALIST."

AUTHOR'S PREFACE.

I have stated in the preface to the first Edition of this work, and
in the "Zoology of the Voyage of the Beagle," that it was in
consequence of a wish expressed by Captain Fitz Roy, of having some
scientific person on board, accompanied by an offer from him of
giving up part of his own accommodations, that I volunteered my
services, which received, through the kindness of the hydrographer,
Captain Beaufort, the sanction of the Lords of the Admiralty. As I
feel that the opportunities which I enjoyed of studying the Natural
History of the different countries we visited have been wholly due
to Captain Fitz Roy, I hope I may here be permitted to repeat my
expression of gratitude to him; and to add that, during the five
years we were together, I received from him the most cordial
friendship and steady assistance. Both to Captain Fitz Roy and to
all the Officers of the "Beagle" I shall ever feel most thankful
for the undeviating kindness with which I was treated during our
long voyage. (Preface/1. I must take this opportunity of returning
my sincere thanks to Mr. Bynoe, the surgeon of the "Beagle," for
his very kind attention to me when I was ill at Valparaiso.)

This volume contains, in the form of a Journal, a history of our
voyage, and a sketch of those observations in Natural History and
Geology, which I think will possess some interest for the general
reader. I have in this edition largely condensed and corrected some
parts, and have added a little to others, in order to render the
volume more fitted for popular reading; but I trust that
naturalists will remember that they must refer for details to the
larger publications which comprise the scientific results of the
Expedition. The "Zoology of the Voyage of the 'Beagle'" includes an
account of the Fossil Mammalia, by Professor Owen; of the Living
Mammalia, by Mr. Waterhouse; of the Birds, by Mr. Gould; of the
Fish, by the Reverend L. Jenyns; and of the Reptiles, by Mr. Bell.
I have appended to the descriptions of each species an account of
its habits and range. These works, which I owe to the high talents
and disinterested zeal of the above distinguished authors, could
not have been undertaken had it not been for the liberality of the
Lords Commissioners of Her Majesty's Treasury, who, through the
representation of the Right Honourable the Chancellor of the
Exchequer, have been pleased to grant a sum of one thousand pounds
towards defraying part of the expenses of publication.

I have myself published separate volumes on the "Structure and
Distribution of Coral Reefs"; on the "Volcanic Islands visited
during the Voyage of the 'Beagle'"; and on the "Geology of South
America." The sixth volume of the "Geological Transactions"
contains two papers of mine on the Erratic Boulders and Volcanic
Phenomena of South America. Messrs. Waterhouse, Walker, Newman, and
White, have published several able papers on the Insects which were
collected, and I trust that many others will hereafter follow. The
plants from the southern parts of America will be given by Dr. J.
Hooker, in his great work on the Botany of the Southern Hemisphere.
The Flora of the Galapagos Archipelago is the subject of a separate
memoir by him, in the "Linnean Transactions." The Reverend
Professor Henslow has published a list of the plants collected by
me at the Keeling Islands; and the Reverend J.M. Berkeley has
described my cryptogamic plants.

I shall have the pleasure of acknowledging the great assistance
which I have received from several other naturalists in the course
of this and my other works; but I must be here allowed to return my
most sincere thanks to the Reverend Professor Henslow, who, when I
was an undergraduate at Cambridge, was one chief means of giving me
a taste for Natural History,--who, during my absence, took charge
of the collections I sent home, and by his correspondence directed
my endeavours,--and who, since my return, has constantly rendered
me every assistance which the kindest friend could offer.

ST. JAGO--CAPE DE VERD ISLANDS.



After having been twice driven back by heavy south-western gales,
Her Majesty's ship "Beagle," a ten-gun brig, under the command of
Captain Fitz Roy, R.N., sailed from Devonport on the 27th of
December, 1831. The object of the expedition was to complete the
survey of Patagonia and Tierra del Fuego, commenced under Captain
King in 1826 to 1830--to survey the shores of Chile, Peru, and of
some islands in the Pacific--and to carry a chain of chronometrical
measurements round the World. On the 6th of January we reached
Teneriffe, but were prevented landing, by fears of our bringing the
cholera: the next morning we saw the sun rise behind the rugged
outline of the Grand Canary Island, and suddenly illumine the Peak
of Teneriffe, whilst the lower parts were veiled in fleecy clouds.
This was the first of many delightful days never to be forgotten.
On the 16th of January 1832 we anchored at Porto Praya, in St.
Jago, the chief island of the Cape de Verd archipelago.

The neighbourhood of Porto Praya, viewed from the sea, wears a
desolate aspect. The volcanic fires of a past age, and the
scorching heat of a tropical sun, have in most places rendered the
soil unfit for vegetation. The country rises in successive steps of
table-land, interspersed with some truncate conical hills, and the
horizon is bounded by an irregular chain of more lofty mountains.
The scene, as beheld through the hazy atmosphere of this climate,
is one of great interest; if, indeed, a person, fresh from sea, and
who has just walked, for the first time, in a grove of cocoa-nut
trees, can be a judge of anything but his own happiness. The island
would generally be considered as very uninteresting, but to any one
accustomed only to an English landscape, the novel aspect of an
utterly sterile land possesses a grandeur which more vegetation
might spoil. A single green leaf can scarcely be discovered over
wide tracts of the lava plains; yet flocks of goats, together with
a few cows, contrive to exist. It rains very seldom, but during a
short portion of the year heavy torrents fall, and immediately
afterwards a light vegetation springs out of every crevice.
