In the course of an investigation of the nutritional requirements of insects in mineral elements, we were confronted with a peculiar instance of an effect exerted by salt ions upon the production of one of the vitamins. The wax moth Galleria melonella can be reared on a medium composed of one part of yeast and two parts of wax. However, if in place of commercial bakers' yeast, yeast grown in the laboratory be used, the result will depend upon the composition of the culture medium.
