To form a just estimate of the relative position of any science at a given period, it is necessary that the prominent events in its history be rightly under- stood. It seems, therefore, expedient to commence this discourse with a slight sketch of the rise and progress of zoological science ; or, more properly, of the progressive discovery of the forms, structures, and habits belonging to the animal world ; a world replete with such an infinity of beings, each pos- sessing so many peculiarities of habit and economy, that, notwithstanding the united efforts of human research for thousands of years, there is not one of them whose history, as yet, can be pronounced complete. (2.) The vast and diversified field of enquiry over which zoology extends, and the many distinct por- tions into which it is now distributed, rendti' it extremely difficult to embrace the whole in one general exposition. For it has happened, that at one period of time while our knowledge has made gigantic progress in one department, it has been stationary, or even retrograde, in others; and at RISE AND PROGRESS OF ZOOLOGY 3 another epoch we find that original research has been abandoned, and the technicalities of system and nomenclature alone regarded. To meet the first difficulty, and to preserve, nevertheless, a connected narrative, it seems advisable to treat the subject historically; and pre-supposing certain epochs in this science, to detail the peculiar charac- teristics of each. This will of course lead to some enquiry into the merits of those who have successively promoted or retarded the progress of knowledge ; or who have been the founders of systems and methods, which for a time have endured, and then been laid aside. The revolutions of science are almost as frequent, and often more extraordinary, than those of political institutions. Both are results, not so much of the talents or efforts of large communities acting simultaneously, as of the influence of some one individual, whose qualities, good or bad, have not unfrequently worked the overthrow of laws, and modes of thinking, which had long been supported by the voice of a nation. It is, therefore, the part of the natural not less than of the political historian, to trace the causes of such revolutions, as far as possible, to their sources ; and not to rest contented with the bare enumeration of the facts themselves, or of the results which followed. (3.) Nor is the above the only difficulty of the task before us. To estimate aright the progress of this science, it is essential to draw a just distinction between analogical research and systematic arrange- ment; or, in other words, between the minute in- vestigation of the properties and characters of an animal, and its subsequent arrangement among other B 2 4 STUDY OF NATURAL HISTORY. animals. It has been the misfortune of those who have written in some respects ably upon the rise and progress of zoology, that this distinction has either not been perceived, or has been entirely set aside. Hence it has resulted that praise and blame have been frequently misapplied; while discoveries of the highest interest have been quite overlooked in the fancied importance attached to the maker of a system, or to the industry of a nomenclator. Without, at present, entering further into these essential differences between the labours of naturalists, we must bear in mind that all true knowledge of the laws of natural combination takes its rise from minute analysis ; and that the value of a system is to be judged of according to the degree with which it arranges in harmonious order, all the various and infinitely diversified facts resulting from analysis. Of artificial systems there may be no end, because the materials of which they are composed show a diversity of relations : each system may differ from the other, yet each may have some- thing to recommend it. But with the materials employed for their construction the case is quite different : the analysis of a species, if correctly made, remains for ever, unchangeable and unchanged : it is permanent ; it cannot be gainsaid, nor does it perish with the system into which it may be incor- porated. The system may be overthrown, yet the analysis remains. True it is that minute research is of more easy accomplishment than the power of ge- neralising : the one requires only a simple accuracy of observation, the other an enlarged and compre- hensive judgment. But, when once a system, like that RISE AND PROGRESS OF ZOOLOGY. 5 either of Aristotle or of Linnaeus, has been framed, it is easy for a host of imitators to follow, each making some fresh modifications, or some small improvements upon the models before him; and thus dazzling the world with a new system, which the inventor would never have composed, had he been left to his own unassisted powers of com- bination. In estimating, therefore, the respective merits of the two classes of naturalists here alluded to, we shall be obliged to assign a much lower station to some names than has been done by our predecessors, and transfer that praise which has been bestowed upon them to others whose labours, although less brilliant, have more contributed to the advancement of science. (4.) In reference to the above observations, we shall now take a rapid sketch of the history of zoology under the following epochs : 1. Its found- ation by Aristotle ; 2. From the revival of learning to the time of Linnaeus ; and, 3. From the appear- ance of the Systema Naturae of Linnaeus, to that of the Regne Animal by Cuvier. (5.) The state of natural history, in the early ages of the world, must ever remain more a matter of conjecture and of theory than of positive fact. Some acquaintance with the properties of animals was cer- tainly possessed by our first parents, who were en- abled, by the Divine agency, to assign names to tne beasts of the field, and to distinguish such as were adapted to their wants. The wisdom of the wisest of men, also, was extended to the works of that God whom he worshipped ; but these and similar B 3 O STUDY OF NATURAL HISTORY. .ntimations in ancient history, whether sacred or profane, must not be interpreted too literally, or be supposed to imply more than that the knowledge of natural history, possessed by the early inhabitants of the earth, was commensurate with what was known of astronomy or other of the physical sciences. (6.) Passing over, therefore, those obscure ages, when all human learning was in its infancy, we may date the rise of zoology, as a study, from the time when the immortal Aristotle directed the powers of his mind to the animal world ; and in his famous book, TIspi ZuSv c I
