On the other hand, in plants and probably also in animals, a point is eventually reached in the difference of the two sides which is prejudicial to the life of the variety or species. Were not this the case, wild animals would doubtless be as asymmetrical in their coloration as our artificially protected domestic animals. While intercrossinn; makes for asymmetry, inbreeding; seems to lead to symmetry "in the markings. Mr. Prazak tells me the Craddock, an inbred race of mountain zebras, are remarkably symmetrical in their Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Ewart, J.
