Among other things, the first two months were spent in getting a feel from the faculty for their hopes and aspirations and receiving input from the veterinary profession in Ohio as to their greatest needs. The Ohio veterinary profession gave an early indica tion of continued interest in upgrading their knowledge of the science and art of veterinary medicine. The level of veterinary practice in Ohio is indeed high already, due primarily to the profession's history of emphasis on Continuing Education. When one considers that four years of veterinary education costs the State of Ohio at Dean Leslie E. McDonald least $40,000, it becomes obvious that the State cannot allow its graduates to become obsolete. Science is ad vancing so rapidly that the scientific body of knowledge doubles approximately each ten years. Combined with the fact that we retain only a percentage of the material originally learned, it is essential that the Continuing Education program be fostered in Ohio. The College of Veterinary Medicine is pleased to share this responsibil Appointment of Dr. Koestner as Chairman of the ity with the State Associations.
