This classification of the Materia Medica, being designed for the use of nurses, follows the order in which Anatomy is commonly taught in training schools for nurses, as it is thought that the study of those remedies most frequently employed in diseases of the various systems of the body, taken in conjunction with the anatomy and physiology of each system, may induce a clearer comprehension of both our Materia Medica and Anatomy, and at the same time serve to fix both in the mind.
