Not many generations ago physiology was taught in connection with anatomy only, and was a simple statement of the functions, as then understood, of the various structures described by the anatomist. It was Haller, who in his "Elements of Physiology,"1 outlined the field of physiology and clearly established the boundary line between that subject and anatomy. Since Haller's time physiology has been recognized as a separate branch of medicine and soon after the publication of Haller's Elements, provision began to be made by the medical faculties for the teaching of this subject in a separate department.
Begun as an appendage of normal human anatomy, it continued as normal human physiology, gradually broadening into animal and plant physiology. Great as has been the activity in thefield of morphology, that in the field of physiology has been scarcely less until the mass of facts and principles of physiology already firmly established
