Aristotle noted that living things develop according to type. If we are to ascribe development of kinds to natural selection we must believe that the plan of an organism is incomplete and tenuous; so much so that among the chance variants there are some which are superior to their parents, along with others which are inferior. Yet among the variants which are hereditary, nearly all are inferior and this study describes such a strain. The data favor the idea that the type is important. A tomato plant with an extra cotyledon might be considered an advantageous type but in these observations it was found to be inferior in germination, rate of growth, and resistance to frost. A few morphological peculiarities were noted.
