These early observers of the effect of hybridization offered many fantastic explanations of the phenomena they reported. Not until a century later did Cotton Mather (whose theological eminence has distracted attention from his botanical attainments) offer the correct explanation for the occurrence of many colors on a single ear of maize. MORE RECORDS OF PLANT HYBRIDIZA TION BEFORE KOELREUTER Conway Zirkle University of Pennsylvania* IN a recent issue of this Journal, the writer^^ described some early records of plant hybridization which had escaped the attention of the his- torians of botany. Since the publica- tion of this paper, several unpublished documents have been found which not only clarify and supplement some of our existing records, but also bring to light the work of new investigators whose really important contributions have been overlooked. Indeed, from the very beginning, the development of genetics has been retarded by the fail- ure of biologists to recognize the sig- nificance of hybridization. We can safely estimate that thirty years were lost by their neglect of Mendel. But Mendel was not the first to be ignored. One hundred and forty years before he published, another Cleric, an English- man, casually observed the crossing of "pease," and noted the occurrence of different kinds in the same pod.
