A male Hereford calf about 4 months old was brought into the Stange Memorial Clinic Dec. 12, 1958. The owner gave the history that it had only one testicle. Upon thorough external physical examination only the right testicle could be palpated which was in its normal position in the scrotum. A cryptorchid was suspected after this examination.
