Of the survivors on this day one weighed -06 g. and the other -11 g. The smaller one, which experience showed would have died on a tomato diet, was transferred to knotgrass, and in nine days it outstripped the larger one and then grew rapidly and uninterruptedly, pupating with a weight of -94 g. on the 50th day of active life.

The remaining one continued to grow slowly on a diet of tomato foliage till the 46th day, when it ceased to feed for two days and lost weight. A ripe tomato fruit was then supplied to it and it fed readily on this for a few days, subsequently feeding alternately on foliage and fruit. It was not weighed after the 57th day but it was seen to be feeding little and died on the 76th day. The growth of this series fed solely on tomato, is shown in Diagram I by the continuous line, and is in striking contrast to the development on knotgrass.
