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, Gaubius, and Sydenham, have expressed their desire of a work of this kind, the great object of which is to fix pathognomies to every disease; or in which all diseases are divided into certain classes, orders, and genera, founded on distinctions taken from the symptoms only, without regard to remote or proximate causes.

Under the article Medicine, we have mentioned some of the most accurate nosological arrangements; and have here only to add, that, in 1776, Dr Sagat, at Igław in Moravia, published a Systema Morborum Symptomatum, octavo, which is an useful abridgment of the work of M. Sauvages, with some alterations and additions. See Medicine, n° 123.
