In meiosis-I crane-fly spermatocytes 3 autosomal half-bivalents move to each pole in anaphase while the 2 sex-chromosomal univalents remain at the equator. The sex chromosomes move to opposite poles only after the autosomes reach the poles; the sex chromosomes start to move polewards about 25 min after the autosomal half-bivalents have begun to move. We irradiated portions of single autosomal s...

We present a kindred of 29 persons affected with erythromelalgia (erythermalgia) in 5 generations. This paper updates the family reported by Burbank et al. [1966].
