The heifer (seen alive in November, 1962) appeared in good flesh, and her activity did not seem hampered by her cervical heart. Casual observation revealed that the animal's heart was located between the thoracic inlet and the midcervical region. The heart protruded laterally 3-5 cm on either side in the normally loose tissues of the ventral neck. As she stood quietly the heart moved in a cranio-caudal direction with each contraction; when she walked, the heart swung from side to side.
