Veit and Esch have recently given us the most complete and detailed study of a vertebrate embryo during the period of somite formation that has ever appeared. All the labor and study expended upon it has been Well worth while, as human embryos of this period are very rare. The specimen is certainly normal and the preservation above reproach. The embryo has eight somites and belongs to the beginning of the third Week, a period which Prof. H. M. Evans and I have been studying for some years. Most of Veit and Esch’s findings fit well into the sequence of events as We have interpreted it from our series of embryos. There is, however, a radical disagreement in our interpretations of the nervous system, and in View of the great importance of the Veit embryo to human embryology, it would seem wise to call attention to the matter.


In his first paper based upon this embryo (’18), as well as in the complete description (’22) Veit has adopted a slight modification of the traditional interpretation of the nervous system in young human embryos. This seems to have originated with Kollmann (’89) in his description of the celebrated embryo ‘Bulle,’ which he had studied simply as a whole mount in balsam. The identification of the regions of the brain was, in the nature of the case, almost wholly subjective. The subsequent Writers who have ventured interpretations of the nervous system of embryos younger than ‘Bulle’ have followed Kollmann more or less closely. They have all made the forebrain relatively enormous and the hindbrain insignificant in size. None of these workers
