NOSOLOGY, is a Greek word signifying a discourse or treatise of diseases; otherwise called pathology. The importance of a comprehensive and accurate nosology has been long and generally allowed. Baglivi, Boerhaave, Gorter, Gaubus, and Sydenham, have expressed their desire of a work of this kind, the great object of which is to fix pathognomons to every disease; or in which all diseases are disposed into certain classes, orders, and genera, founded on distinctions taken from the symptoms only, without regard to remote or proximate causes.
