To quickly assess the difficulty of the text, read a short excerpt:
Muscicapidae. MeUphagidae. Turdidae. CincUdae. General Remarks on the Classification of the Passerines. 51 Conidae. Paradiseidae. Tanagridae. FringiUidae. Syhidae Hirwudmidae Alaudidae Certhidae. Tribus II. Tracheophones. Windpipe-voiced Birds. Myiotheridae. Scytalopidae. Anabaiidae. Tribus III. Pioarii. Pecking Birds. Opistkocomidae. Tyrannidae. Musophagidae. Trockilidae. Galbulidae. Fissirostres. Picidae. Colidae. Cuculidae. Prionitidae. Bucconidae. Meropidae. Trogonidae. Lipoglossi. Bhamphas...tidae. Coraciadae. Psittacidae. This classification is not free from objections, and it may be said against it, as would be said against the orders of Oscines, and Picarii, that Setophaga and Sylvicola are thus placed nearer to one another than Setophaga and Psiiiacus; and similarly Hirundo and Cypsehis, nearer than Cypselus and the Psittacidae. If we further consider, that there are no external characters which correspond to internal structure, the most natural classification would be to simply make the families, carefully founded, and united by the form of their larynx, succeed one another in such a way that the Singing Birds and the Parrots should be at the ends.
