In the article titled "Growth Hormone Deficiency, Brain Development, and Intelligence," published in the June Journal (132:565-572, 1978), several errors occurred in the text and in Tables 1 and 2. In Table 1, column 4 (Inactive HGH) instead of column 3 should have an "X" under it for the Frankel and Laron entry. In Table 2, column 12 (Gonadotropins), the PE-10 entry under this column should have a paragraph symbol, not the section mark symbol. On p 566, right text column, fifth and sixth lines from the bottom should read "(based on Tables 2-5 and 2-6...)" not 2 through 5 and 2 through 6. On p 567, left text column, third line from the bottom it should read "≤ 8μg/100 ml." And on p 567, middle text column, sixth line from the top, it should read "17-OHCS," and not "17-OHCS."
