The heating of E. coli strains W6 and 15 at 55 to 60 C (below the melting temperature of deoxyribonucleic acid) increased the spontaneous rate of mutation (S. Zamenhof and S. B. Greer, Nature 182:611, 1958). Heat also apparently caused some depurination of deoxyribonucleic acid (S. B. Greer and S. Zamenhof, J. Mol. Biol. 4:123, 1962), and hence must also induce chain breakage. Temperature effects on the production of mutations have also been found in Tradescantia (K. Sax, Genetics 22:523, 1937), Drosophila (H. H. Plough, Cold Spring Harbor Symp. Quant. Biol. 9:127, 1941), and Neurospora (B. J.
