Excerpt from The Biological Problem of to-Day: Preformation or Epigenesis? The Basis of a Theory of Organic Development Shortly after the appearance of Dr. Oscar Hert wig's treatise 'praformation oder Epigenese I published in Natural Science (1894) a detailed abstract of it. But the momentous issues involved in the problem of heredity, and the great interest excited by Dr. Weismann's theories, make it de sirable that a full translation should appear. By the kindness of Dr. Hertwig and his German pub lisher, this is now possible. I have prefixed an introduction, written for those who are interested in the general problem, but who have little acquaint ance with the technical matters on which the argument turns. In the actual translation I have tried no more than to give a faithful rendering of the German. After no little perplexity, I have rendered the German word Anlage as 'rudiment.' It is true, a double meaning has been grafted upon the English word, and it is widely employed to mean an undeveloped structure, without discrimination between incipient and vestigial character. I use it in the etymological sense, as an incipient structure. For the difficult words, Erbglcfich and Erbungleich, a succession of new terms have been suggested. Here I use for the first term the word doubling, ' for the second differentiating.' About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at ...
