trigonometrical survey of the colony; and, in closing on Mount Riddell, a
survey extending two degrees within the tropics, the near coincidence of
his intersections with that summit, as fixed by his survey of 1830, could
not but be very satisfactory to the author.

The geological specimens collected during this journey have been
deposited in the British Museum, and their original locality is shown on
the maps by the numbers marked upon the specimens, so that they may be
available to geologists; hence, in the progress of geological science,
the fossils now brought from these remote regions will be accessible at
any future time, and something known of the geology as well as of the
geography of the interior. As Professor Forbes most readily undertook to
describe the freshwater shells after the work had passed through the
press, that portion of the collection also has thus been brought under
the notice of geologists.
