"What distinguishes the practice of the medical profession, in treating the diseases and repairing the injuries of the genus homo, from that of the veterinarian? . . . . It is the worth of man, he being a rational being, the other being an animal destitute of reason. . . . . I would further define the mind as the superintending, the guiding power of corporeal manifestations; it directs all the movements of the body, over which it has complete control; it is to the body what the engineer is to the steam engine, the body being but a mere machine suited to develop the operations of the mind, and preserved and kept in order by the organic functions."
The above question, with its answer in two parts, is from an article by Dr. John M. Farrington, in the JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION of March 31, 1894.
