Book excerpt: Excerpt from Observations on the Genus Unio, Vol. 5: Together With Descriptions of New Species in the Families Unionid, Colimacea and Melaniana, Read Before the American Philosophical Society, and Originally Published in Its Transactions I am aware that many persons doubt the existence of so extended a production of species, but this arises from the want of a knowledge of them, closely cultivated and analytically examined. An organic form, instituted by nature must be recognised as dis tinct, for it will remain in a state of autonomy to the end of its term. It is the duty of the zoologist to bring to the investigation an eye practised in discrimination, and a judg ment experienced in analysis, as well as also an honest intention of purpose, that he may give the best and most accurate results to his investigations.
