described are added; besides many others which
display important peculiarities of anatomical structure.
As far as it has been possible, the Author has drawn his illustrations from British species; for these are within the reach of all: and many young readers, it is hoped, may be induced to verify the statements they read in books, by personal observation of the living types that surround them. By this means, the knowledge acquired will possess an assurance (and a charm also) which mere reading can never bestow.
Finally, the exhibition of the wondrous structure of living beings, and its beautiful and perfect adaptation to the instincts implanted in them, should produce a reverential admiration of God as He has manifested Himself in His works of Creation, and be, under the Divine blessing, one of the means of leading the heart to an acquaintance with His work of Grace.
London, June, 1848.
