attention, a great delay is avoided by adopting this method of
publication, which must otherwise have been incurred before the
matei’ials could have been made known.
An Account o f the Voyage, drawn up by Captain FitzRoy,
(and to which I have added a volume) being on the point of
publication, I shall not in this Work enter on any minute details
respecting the countries which were visited, but shall merely give
a sketch o f the geology in the introduction to the part containing
Fossil Mammalia, and a brief geographical notice in that attached
to the account o f existing animals. At the conclusion o f this
Work, I shall endeavour to place together the leading results in
the natural histoiy of the different countries, from which the
collections were procured. I may here state that Mr. Owen
has undertaken the description o f the Fossil Mammalia; Mr.
Waterhouse, the Recent Mammalia; Mr. Gould, the B ird s ;
Mr. Be ll, the Reptiles ; and the Rev. L. Jenyns, the Fish.
Wliatever assistance I may obtain in the invertebrate classes,
will be noticed in their respective places. The specimens have
been presented to the various public museums, in which it was
thought they would he o f most general seiwice ; mention will be
made in each part where the objects described have been
deposited.
