The only original work that has appeared in this country similar to our own, is the Zoological Miscellany by Dr. Leach, which, as it was discontinued after the third volume, it may be presumed was unsuccessful: although little can be said of many of the figures in the early volumes, those in the latter are much to be praised, and the whole are original; the descriptions also abound with details highly interesting to the scientific world, for which indeed the learned author principally intended it; nevertheless it is a question, whether science in the end would not have been equally, and perhaps more advanced, had this work been more adapted to general readers. Instruction in these days of refinement must be made easy, palatable, and enticing; the eye must be pleased, while the understanding is improved, and Wisdom in her simple dignified garb will often be deserted for Ignorance, decked out in the glittering trappings of Folly. The _Naturalist's Miscellany_ conducted by Dr. Shaw, in its miscellaneous nature also resembled the present work, and reached to the extent of twenty-four volumes. What an invaluable fund of information these might have contained had their contents been original! Unfortunately, however, the exceptions are so few, that the whole may be termed a loose compilation, the descriptions being mostly given in as few words as possible, and the figures not only copied from wretched representations found in old authors, but often coloured from their descriptions only! It is indeed lamentable that the Author, whose talents and abilities were unquestionable, should have exerted them so little, and thus have descended to the rank of a voluminous compiler, for little better can be said of the General Zoology, begun and continued under his name: little original matter can there be found, excepting in the latter volumes, yet even in these no notice whatever is taken of the immense number of new species discovered in Africa by Le Vaillant, and long ago published in the _Oiseaux d'Afrique_: the engravings also are in like manner copied from old prints, enlarged or diminished as occasion offers, without even a regard to the selection of the best. It may be as well to observe in this place, that a great number of generic distinctions have been made in the two last volumes; which, as they have not been followed by any of the great and acknowledged Zoologists on the Continent, and appear to us in many instances trivial and unnecessary, will not be adopted in this work.
