etted, for the cause of science and literature over the
world, that the great traveller has been prevented from setting out
late in life to a fresh region of discovery. It has left the remainder
of his life, and his yet undiminished powers, to illustrate and
explain what he has already seen. To do that, was enough for the
ordinary span of human life.

Humboldt's works relating to the New World are very numerous. I. He
first published, in 1805, at Paris, in four volumes quarto, the
_Personal Narrative_ of his travels from 1799 to 1804. Of this
splendid and interesting work, several editions have since been
published in French, in twelve volumes octavo. It is upon it that his
fame with the generality of readers mainly rests. II. _Vues des
Cordilleras et Monumens des Peuples Indigenes de l'Amerique_--two
volumes folio: Paris, 1811. This magnificent work, the cost of which
is now L130, contains by far the finest views of the Andes in
existence. Its great price renders it very scarce, and not more than a
few copies are to be met with in Great Britain; but a cheap edition,
without the great plates, was published at Paris in 1817. III.
_Recueil d'Observations Astronomiques, et de Mesures executees dans le
Nouveau Continent_: two volumes quarto. This learned work contains the
result of Humboldt's astronomical and trigonometrical observations on
the lunar distances, the eclipses of the satellites of Jupiter, the
transit of Mercury, and upwards of five hundred elevated points in the
New World, taken from barometrical observations, with all the
requisite allowances and calculations carefully made. IV. _Essai sur
la Geographie des Plantes, ou Tableau Physique des Regions
Equinoxiales_: in quarto, with a great map. V. _Plantes Equinoxiales
recueillies au Mexique, dans l'Ile de Cuba, dans les Provinces de
Caraccas, &c._: two volumes folio. A splendid and very costly work.
VI. _Monographie des Melastomes_: two volumes folio. A most curious
and interesting work on a most interesting subject. VII. _Nova Genera
et Species Plantarum_: three volumes folio. Containing an account of
the botanical treasures collected by him in the New World, and brought
home in his magnificent herbarium. VIII. _Recueil des Observations de
Zoologie et d'Anatomie comparee faites dans un Voyage aux Tropiques_:
two volumes quarto. IX. _Essai Politique sur la Nouvelle Espagne._
1811: two volumes quarto. Of this admirable work a subsequent edition
has been publish
