Abstract
THE most important criticism in the review on May 13 of “The Origin of Vertebrates,” by Dr. W. H. Gaskell, is based on a dogmatic view as to the fundamental distinctness of the germ layers and their predetermination for the formation of certain organs. It is evident that your reviewer regards this as a settled fact. It is therefore only fair to point out that this is by no means the opinion of all morphologists. Indeed, Morgan, Hertwig, Braem, Driesch, Conklin, Jenkinson, and many others grant little phylogenetic value to the germinal layers.
