In order to bring this vast symptomatology within the ready reference of the busy practitioner, Hahnemann, himself a physician of large and extensive practice, and, hence, in need of labor-saving devices, re-arranged it in anatomical order, which has been found so practical for everyday use, that it has been universally adopted by all our authors on Materia Medica. He begins with the head and first records all the symptoms of the mind, sensorium, etc.; then those of the eyes, nose, face, etc., downwards, placing together all the symptoms relating to each section. In this way the original provings were dissected, destroying the order of development of the symptoms, but greatly facilitating ready reference.
