The primary growth was usually situated in the axilla or the groin, and metastases occurred in the lungs. In a small proportion of cases in the other groups and in every case in the group receiving tethelin throughout the duration of life (tethelin fed males) the only new growths detectable by naked eye exami nation were situated in the lung; and these, in the tethelin - fed group, were very small, frequently but 1 to 4 mm. In diameter. In the more typical cases, involving a primary growth in the axilla or groin, death usually occurred within one month of the appearance of a manifest lump. The diet of the normal animals consisted of crushed barley and water ad libitum, fresh leaves of lettuce twice a week, dry hard unsweetened biscuit pilot bread) once a week, and 5 cc.
