The serum of a Memphis Negress was found to be incompatible with all donors tested. She had had 11 pregnancies and had received 16 pints of blood between 1955 and 1957. She was found to be strongly Js(a+) and her four living children were all Js(a+). Her serum was tested against the red cells of two sisters believed to be homozygous for Js a because all their ten children are Js(a+). They were found to be compatible. Thirteen of 1,269 Memphis and Milwaukee Negroes were found to be ccmpatible. Twelve of these were tested with anti‐Js a and all were positive. The probability of selecting 12 consecutive Js(a+) Negroes by chance is only four in a billion. The proportion of 0.0102 non‐reactors among the 1,269 Negroes tested agrees well with Giblett's estimate of 0.0106. The antibody has therefore been designated as anti‐Js b . No Js(b–) individuals have been found among 1,005 Caucasians tested.
