Excerpt from Classification of the Animal Kingdom: A Lecture Introductory to the Course of Anatomy, in the Philadelphia School of Anatomy, Delivered by D. Hayes Agnew, M.D., On Tuesday Evening, October 10, 1860In Radiates the nervous system is placed as a ganglionic collar around the mouth, and from which the nervous cords run like rays to the different prolongations of the animal. The skeletons of such are firm and frequently calcareous in their consistence. It is to this last division of Cuvier that the greatest objections are urged. It is entirely too heterogeneous in composition - its elements too diverse in their organic relations.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
