Excerpt from Special Anatomy of the Gaseopoa of the United States When the researches were commenced in the winter of 1844, of which the following chapters are the result, it was the proposition of Dr. Binney for the author to give a complete anatomical and physiological description of the terrestrial Gasteropoda of the United States, includ ing the special and general anatomy, with the embryo logy of the several genera. Before the Special anatomy was fairly completed, the death of Dr. Binney put a stop to the work; and, a different course of observation hav ing occupied the author's attention, the subject is now published, after a long delay, in its present incomplete state, from notes taken at the time.
