Excerpt from Introductory Lecture to the Course on the Principles and Practice of Surgery, in the Medical Department of Pennsylvania College: Session of 1846-47 The constitution is also varied, in different individuals; according to age, sex, condition in life, mode of living, occu pation, physical and moral training, and in the same person from week to week, or from day to day, precisely as the ascertained laws which govern the operation of agents upon the system are conformed to or transgressed - there being a necessary connection and mutual dependence among all the organs of the body, and also particular relations between them and the objects of inanimate nature. This connexion and dependence, and these relations, can never be infringed without suffering. Man cannot escape these laws. They pertain to his existence; they are the ordinances of the Creator himself. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
