Daudin's Natural History of Reptiles has considerably increased the number of species, and has brought us ac quainted with many that were either not known before, or whose place in the systematic arrangement had not been distinctly ascertained. Though the matter of this work is excellent, we cannot, however, say so much for the exe cution of the plates. The figures are in general so deeply shaded, as to render it difficult to observe the characteris tic lines, scales, and dots, that distinguish the species.
Dumeril, whom we have already noticed as the assistant of Cuvier, has published two works on natural history, which contain, among other animals, the new systematic arrangement of reptiles. These are, Zoologie Analytique, published in 1806, and Traite Elementaire d'Histoire Na turelle, in two volumes, of which the second contains the animal kingdom. His arrangement is so near that of the other distinguished naturalists of the French school, that we need not detail it here, especially as we have already given a summary view of it under the article AMPHIBIA.
We might have extended these historical notices to a much greater length ; but we consider it unnecessary. We have given a succinct account of the principal writings on Herpetology, and shall now conclude this Part of our sub ject with a list of other works, to which the reader may refer for additional information.

Before commencing our account of the structure and economy of reptiles, it is necessary, in order to render that account intelligible, that we should here give a comprehen sive view of the arrangement which we mean to follow in the Second Part of this article.
On carefully comparing the various arrangements of rep tiles which have been adopted by modern naturalists, we are disposed to prefer that of the French school, though we think it unnecessary to carry the subdivision of the genera so far as has been done by Dumeril and some of his associates.
Exclusive then of the serpents, which, as we have seen, constitute the third order in this new arrangement, the rep tile tribes are distributed into three orders, CHELONIANS,
