"According to present-day criteria the age of this embryo may be estimated as included in the period 18-21 days, and probably in the earliest part of this period. quote Born's estimate of the age of embryo "Klb" as 10-14 days. But if we take into account the more recently accepted criteria of age in early embryos, this age must be judged to be considerably underestimated. I shall show reason to regard embryo " Klb" as distinctly more advanced in development than embryo H3."

"Fig. 23. Four stages in the closure of the neural tube in human embryos possessing from 5 to 14 somites. A, embryo Klb, 5-6 somites, from Keibel u. Elze (Normentafeln); B, embryo No. 391, 7 somites, Mall collection, after Dandy; C, Eternod's embryo, 2.11 mm. long, 8 somites, after Kollmann; D, embryo 2.4 mm. long, 14 somites- estimated age 14 to 16 days. (C and D after Kollmann.) posterior ends of* the neural plate are found in the median line. In the closure of the tube it is the lateral portions of the anterior and posterior margins that unite last, and so the neuropores are found dorsal to what was originally the extreme ends of the neural"
