3. Admitting, however, that we may have expressed too sanguine expectations of commercial advantages, either within our own reach, or gradually to be unfolded at some future period, as the result of our voyages of discovery, we may still be allowed to consider them as a laudable effort to add to the stock of human knowledge, with regard to an object which cannot but deserve the attention of enlightened man. To exert our faculties in devising ingenious modes of satisfying ourselves about the magnitude and distance of the sun; to extend our acquaintance with the system to which that luminary is the common centre, by tracing the revolutions of a new planet, or the appearance of a new comet; to carry our bold researches through all the immensity of space, where world beyond world rises to the view of the astonished observer; these are employments which none but those incapable of pursuing them can depreciate, and which every one capable of pursuing them must delight in, as a dignified exercise of the powers of the human mind. But while we direct our studies to distant worlds, which, after all our exertions, we must content ourselves with having barely discovered to exist, it would be a strange neglect, indeed, and would argue a most culpable want of rational curiosity, if we did not use our best endeavours to arrive at a full acquaintance with the contents of our own planet; of that little spot in the immense universe, on which we have been placed, and the utmost limits of which, at least its habitable parts, we possess the means of ascertaining, and describing, by actual examination. So naturally doth this reflection present itself, that to know something of the terraqueous globe is a favourite object with every one who can taste the lowest rudiments of learning. Let us not, therefore, think so meanly of the times in which we live, as to suppose it possible, that full justice will not be done to the noble plan of discovery so steadily and so successfully carried on since the accession of his Majesty; which cannot fail to be considered, in every succeeding age, as a splendid period in the history of our country, and to add to our national glory, by distinguishing Great Britain as taking the lead in the most arduous undertakings for the common benefit of the human race. Before these voyages took place, nearly half the surface of the globe we inhabit was hid in obscurity and confusion. What is still wanting to complete our geography, may justly be termed the _minutiæ_ of that science.
