A study of 149 hamsters indicates that there are periods in life when the animal is immune to tumor induction by a known virus. By studying normal serum protein levels, standards were established for the adult age and for the tumor forming period. The data emphasize the importance of the immunologic status of the host for virus induction of tumors.
