Excerpt from Biological Bulletin of the Marine Biological Laboratory, Vol. 29: Woods Hole, Mass A study Of this material by my students and myself has brought to light a situation so interesting, but withal so intricately com plex, that I almost despair of being able to render an intelligible account of it. Yet I cannot but be impressed with the unique ness Of the data and with the fact that it contains clews, afforded by no other material, as to methods Of attacking some Of the problems Of the mechanics Of hereditary transmission and Of the development Of organic symmetry. In presenting the results Of the study Of the heredity Of band and scute anomalies I have found that the problems Of heredity, and that Of the symmetrical distribution Of these inherited characters among the quadruplet embryos, are inseparably parts Of a larger problem that has to do with the mechanics Of organic symmetry. When, for example, it is found that a bilateral anomaly in a mother is inherited unilaterally in the various Offspring and appears in reversed symmetrical relations in twins, we have something more than a case of simple inherit ance. When again we find a unilateral anomaly in one pair appearing bilaterally without reversed symmetry in the opposite pair we see the problem in a more complex form. When, still further we note that an anomaly of a single scute in the mother is inherited as such in some of the Offspring and as a whole series Of anomalous Scutes (a band anomaly) in others, we begin to Suspect that the problem is too intricate for any Simple solution and that only in certain of its aspects is it likely to yield to analysis. Yet it is our duty to carry the analysis as far as our data allows. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
