Note F — INTRODUCTION
Reading edition
Romanes, in “Darwin and After Darwin,” chapter iv., says that the embryo is a résumé or recapitulation of the successive phases through which the being has been developed, with explainable omissions. On page 102 he tells of the young salamander that is so complete in its gills shortly before birth that if it is removed from the womb and placed in water it will be able to live, breathing like a fish through its gills.
