The natural history of North America has been regarded with especial interest wherever the sciences have been cultivated since the discovery of the continent. Our advantages for study have been much superior to those possessed by former writers in America. There never was in the United States, until within the last ten years, a library of Natural History, approximating in any considerable degree to completeness, nor affording the necessary facilities for the study of Ornithology.

Nor until within that period was there any collection sufficiently comprehensive to answer the purposes of comparison and general research. In various branches of Natural History, but especially in Ornithology, these most important and desirable objects have been fully accomplished in the formation of the Library and Museum of the Academy of Natural Sciences of Philadelphia,—a result for which science is indebted, not to the Government, nor to public patronage of any kind, but to strictly private enterprise and individual scientific taste.
