Fig. 1. Menstruation age and copulation age taken from the curve constructed by me and published in the Manual of Human Embryology
All embryos are entered with CR. length. I have also added for the sake of comparison the curve giving the convention of His. NL and CR give the neck-rump and crown-rump lengths respectively, according to His. The fertilization age is according to Bryce and Teacher for smaller embryos, and according to Tricpel for larger ones. The dots record the menstrual age of the embryos under consideration, and the squares the copulation age. The crossed squares mark the best records, as mentioned in the text. It may be noted again that the curves are not constructed from these records, but the records are entered to test the curve.
