The advances in general medical science and practice have also necessitated great elaboration of the resources for the study and treatment of the physical condition of the patients. Instruments of precision, laboratories, x-ray departments, dental and surgical operating rooms, massage and hydrotherapy departments, facilities for eye, throat, nose, and ear examinations and treatment, and all the other means of determining disease processes and applying proper treatment have been supplied and the methods and standards of modern clinical medicine and surgery are utilized.
