who seek to discover and admire the good and the beautiful in the works of nature. Our next publication in this branch will be a volume on Exotic Moths and Hawk-moths,—an imperfectly known department of the subject,—for which drawings of new and splendid species are now in preparation by Mr. Westwood, to whose elegant pencil we have likewise, as will be seen, been largely indebted on the present occasion, in the volume which this accompanies.
The next volume of our work, which will form the thirtieth, will embrace the natural history of a very remarkable group of quadrupeds, and one with which the public are very little acquainted, namely, the Marsupialia, or Pouched Animals, by George Waterhouse, Esq. Curator to the Zoological Society, illustrated with nearly forty Plates from drawings by W. Dickes, Esq. an artist now first employed to contribute to the Naturalist's Library. These drawings have been made with great care and high artistical skill, from specimens which are to be found assembled only in the collection of the Zoological Society of London. It may be added that this will be the first attempt which has been made to give a complete history and representation of this very extraordinary race of animals.
