It is one of the most scientific and best executed works on Indigenous Botany ever produced in this country. "A truly admirable work, which may be honestly designated as so excellent, that nothing can be found to compete with it in the whole range of Indigenous Botany; whether we consider the importance of its critical discussions, the accuracy of the drawings, the minuteness of the analyses, or the unusual care which is evident in the publishing department. After expressing this opinion, we are sure the work will need no further recommendation with the public." _Loudon's Gardener's Magazine._ HARRIS'S AURELIAN; a Natural History of English Moths and Butterflies, together with the Plants on which they feed; also a faithful Account of their respective Changes, their usual haunts when in the winged state, and their standard Names as established by the Society of Aurelians, new and greatly improved edition, containing a complete Modern Nomenclature of all the Species figured in the work, and further Accounts of their Economy, by J.
