All drawings were made by Mr. James F. Didusch according to geometric projection. With the exception of figure 7, which was made from a profile reconstruction, all figures were drawn from the original plaster-of-paris models made from human fetus No. 886 of the collection of the Carnegie Laboratory of Embryology. The number of the model from which each figure was drawn is given, together with the magnification. Note - the magnifications refer to the original print versions, not the online images.
