THE recent demonstration1 of the clear-cut differential effect of streptomycin on the fertility of the equally sensitive Bact. coli K12 mutant strains 58–161 and W677, which show genetic recombination, suggested that analysis of the stimulating effect on recombination of small doses of ultra-violet light, reported by Haas et al.2, might yield interesting results.
