One of these (No. 65) had a low serum thyroxine level. The adults with thyroid nodules (Nos. 59 and 64) and two of the children (Nos. 42 and 61) had normal responses to TSH. Several of the studies listed in Table 20 were performed after subtotal thyroidectomy (Nos. 17, 21, 69, 2, and 20). The results indicate inadequate function of the thyroid rem- nant, even in Nos. 17, 21, and 69, who had been Figure 27.

The serum iodoprotein levels (PBI less 7, I) ranged from 1.5 to 2.9 and did notdiffer significantly from values : in unexposed Marshallese. Figure 28.
