of pulmonary disease in slieep did much to impi’ove the health
of tlie local flocks as well as to advance comparative pathology.
As his growing stature in the University led to his becoming

Medical School, and then President, his concern with medical and
scientific education develojxed, and he played important parts iu
several world conferences on medical education.
