That the prejudiced adherence to the strict Linnaean system, has been the primary cause why Zoology has been more neglected with us than on the Continent, will admit of little doubt; for by shutting the door to all further improvement, it has impressed the generality of our countrymen with an idea, that the highest object of the Naturalist was to label the contents of a museum, and to arrange stuffed animals, like quaint patterns of old china, in glass cases: to thinking minds no less than to the vulgar, this idea has produced a feeling of contempt and ridicule, and very few of those qualified by nature for accurate investigation and philosophic reasoning, have been induced to make the science a study; and thus from such an unfortunate prejudice, to use the words of a powerful writer of the present day, "some future historian of the progress of human knowledge, will have to state that England, till within the few last years, stood still at the bottom of the steps where Linnaeus had left her; while her neighbours were advancing rapidly towards the entrance of the temple[1]." Finally--Linnaeus to a comprehensive genius united indefatigable industry; yet he could not see and study those innumerable productions that have been discovered since his death: in proportion as our knowledge of objects increases, so must our systems change, until the natural one is fully developed; and the question simply comes to this, Whether the Linnaean method should be upheld as a solitary exception to the mutability of human wisdom.
