We cannot too often place before the student those objects in nature which seem more especially to illustrate that wonderful system on which the whole has been created. In the infinite diversity which pervades the works of "Him who made us," two things have obviously been intended: one, the manifestation of His power in the creation of the individual: the other, an illustration of some important truth connected with the spiritual welfare of mankind. The first is manifest, and speaks to our senses: the second is emblematical, and calls for an exertion of those reasoning faculties with which the Creator, for such purposes, aided by those helps he has promised, has given to us. In accordance with this latter assumption, both divines and Naturalists concur in considering Nature as a book of Emblems, "where one thing represents another." That this theory, resting heretofore on general belief, is capable of mathematic definition, we have elsewhere largely demonstrated, (North. Zool.). And if, as regards one division of animated nature the theory is correct, it follows that it will be equally manifested in _all_ other portions of the animal world, when they are sufficiently investigated. Hence it is that remote resemblances between objects, widely different in themselves, can be explained: hence the analogy which the _Glires_ bears to the Hedgehogs, and to the _Ceblepyrinæ_; and hence the resemblance between this shell and the Porcupines; an analogy the more singular, as it extends even to the black and white colour of the spines. * * * * * * [Illustration: JASIA _Australis_.] JASIA Australis, _Australian Jasia-Butterfly._ ---- Family Nymphalidæ. Sub-family Paphianæ. Genus, ---- SUB-GENERIC CHARACTER. See pl. 90. ---- SPECIFIC CHARACTER. _Wings above yellowish white, the outer half of the anterior black with a series of spots disposed in the shape of the letter Y; inferior wings with a black border, margined by cinereous, and an orange spot at the anal angle._ ---- We believe the specimen from which our figures of this new and strikingly distinct butterfly were taken, is the only one which has yet been sent to Europe. It was captured by Mr. Cunningham, who accompanied Captain King, in his voyage to the North West coast of Australia, on the skirts of Careening Bay, Port Nelson, where the Ship Mermaid was hove down; and the officers had more leasure to attend to zoological pursuits. Mr. Cunningham remarked that it flew with great swiftness, in which respect it perfectly resembles the rest of the genus _Jasia_, of which it is a typical example. The geographic range of this group is thus proved to extend from the South of Europe to Australia, but it is entirely unknown in the new world.
