INTRODUCTION. OF THE ARCTIC WORLD.
AKNOWLEGE of the geography, climate, and soil, and a general view of the productions of the countries, whose Zoologic History is to be treated of, are points so necessary, that no apology need be made for introducing them into a prefatory discourse.
It is worthy human curiosity to trace the gradual increase of the animal world, from the scanty pittance given to the rocks of Spitzbergen, to the swarms of beings which enliven the vegetating plains of Senegal: to point out the causes of the local niggardness of certain places, and the prodigious plenty in others. The Botanist should attend the fancied voyage I am about to take, to explain the scanty herbage of the Arctic regions; or, should I at any time hereafter descend into the lower latitudes, to investigate the luxuriancy of plants in the warmer climates.
The Fossilist should join company, and point the variations of primaeval crea∣tion, from the solid rock of Spitzbergen through all the degrees of terrestrial matter: the steps it makes to perfection, from the vilest earth to the precious diamond of Golconda. The changes in the face of the globe should be attended to; the de∣structions by vulcanoes; the ravages of the sea on some coasts, and the recom∣pence it may have made to others, by the retreat of its waters.
The pursuit of these enquiries will also have a farther and more important object. History should be called in, and a brief account given of the population of the more remote countries—the motives which induced mankind to seek re∣treats in climates seemingly destitute of incitements to migration. Particular attention should be paid to the means of peopling the new world, and of stocking it with animals, to contribute to the support of mankind, after the first coloniza∣tion—the increase of those animals, and their cessation, and giving place in a certain latitude to genera entirely different.
