Attention should be paid to the Geology of districts which
iiave not liitherto been examined, and collections of minerals,
rocks, and fossils sliould be made. Detailed suggestions as to
tlie duties of tlie geologist accompanying the Expedition are
unnecessary ; but it seems desirable that, at all sliores visited,
evidence of recent elevation or subsidence of land should be
sought for, and tlie exact nature of these evidences carefully
recorded.
Every opportunity should be taken of obtaining photographs
of native races to one scale ; and of making such observations
as are practicable with regard to their physical characteristics,
language, habits, implements, and antiquities. It would be
advisable that specimens of hair of nnmixed races should in
ail cases be obtained.
Eacli station should have a special number associated with it
in the regular journal of the day’s proceedings, and that number
sliould be noted prominently on everytiiing connected with that
station ; so that in case of labels being lost or becoming indistinct,
or other references failing, the conditions of the dredging
or otlier observations may at once be forthcoming on reference
to tlie number in tlie journal. All specimens procured
should be carefully preserved in spirit or otherwise, and packed
in cases with the contents noted ; to be dealt with in the rvay
wliich seems most likely to conduce to the rapid and accurate
development of the scientific results of the Expedition.
A diary, noticing the general proceedings and results of each
day, should be kept by the Scientific Director, with the assistance
of his Secretary ; and each of the members of the Scientific
Staff should be provided with a notebook, in which to enter from
day to day his observations and proceedings; and he should
submit this diary at certain intervals to the Scientific Director,
who would then abstract tlie results, and incorporate them,
along with such additional data as may be supplied by the
officers of the ship, in general scientific reports to be sent home
to the Hydrograplier at every available opportunity.
The Scientific Staff sliould be provided with an adequate set
of books of reference, especially those bearing on perishable
objects.
Eesolved,—That the Eeport of the Circumnavigation Committee,

In reply to your Letter of tlie 22iid of August, referring to
the Exploratory Voyage of H.M.S. ‘Challenger,’ and desiring
to learn, for the information of the Lords Commissioners of the
Admiralty, what are the precise objects of research which the
Eoyal Society have in view, and in what particular portions of
the Ocean such investigations may, in tlieir opinion, be carried
out with the greatest advantage to science and the best probability
of success, I am directed to acquaint you that the matter
was carefully considered by a Committee, consisting of the
President and Officers, with Dr. Allman, Dr. Carpenter, Dr.
Erankland, Dr. Hooker, Prof. Huxley, the Hydrograplier of the
