The next engraving (fig. 27) offers illustrations of three parallel scries taken from thebirds. The first three are alike in the enormous volume of their beaks; the second have CLASSIFICATION OF BIRDS. 41 elongated, compressed, and pointed beaks, a little hooked at the extremity; in the thirdseries the beaks are straight, conicle, and with equal mandibles. m ^r. ilU. :iO.— lAPvALLEHSJI UF MAMMALIA A>fD BIRDS. 43 THE FEATHERED TRIBES. In the engraving (fig. 28) the parallelism is more remarkable ; it contains two series,formed from two very closely allied families. The swallows and the goatsuckersare distinguished from other birds of the same family by their large and deeply-cleftbeaks. These are distinguished from one another in this, that the swallows have closeplumage and are bii-ds of day, while the goatsuckers have soft pliunage and are nightbirds. A resemblance may also be traced in the claws of the birds thus compared. Most justly was it long since remarked b) Locke: All the great business of generaand species amounts to no more than this, that men make abstract ideas, and, settingthem in their minds with names annexed to them, do thereby enable themselves toconsider things and to discourse of them, as it were in bundles, for the easier and readierimprovement and commmiicafion of tlieir knowledge, whic
