The method for the production of mutations in Aspergillus terreus by ultraviolet radiation is described. The probability of producing "deficient" mutants through chemical changes and the occasional appearance of mutants having increased ability to produce certain compounds is pointed out. Results are given on the per cent of mutation and survival after exposure to λ 2280, 2650, and 2967 Å. The effect of secondary treatment after irradiation and the characteristic appearance of mutations after a relatively small number of spores are killed are reported.
