cies; among the Anseres, which are characterized as having the bill smooth, covered with epidermis, and enlarged at the tip, are the gannet with a bare pointed bill, the divers, the terns, and the gulls, with bills not at all answering to the description given; among the Gralla with a cylindrical bill, are the ostrich with a short depressed one, the boatbill with one resembling a boat, the spoonbill, the heron, the flamingo, and others, whose bills differ from each other as much as from that of the snipes and curlews; the character given to the bill of the Gallinæ agrees with that of many Passeres; and, lastly, the wagtail, the swallow, the tit, the robin, and a multitude of other small birds, have bills extremely unlike those of the goldfinch, bunting, and crossbill, which are referred to the same order. We mention these circumstances, not for the purpose of detracting from the merit of Linnæus, but simply because we are persuaded that many of his generalizations are extremely incorrect, as are in many respects those of all his predecessors, and even of the ablest philosophers of the present age. It is absurd to attempt to thrust the objects of nature into squares or circles, or enclosures of any other form. Every system that has been invented has failed in presenting even a tolerably accurate view of the discrepancies and accordances of the endlessly-diversified forms that have resulted from the creation of an Infinite Power.

The following table presents the Linnæan arrangement of Birds in outline :
