"Figure 1 shows the +increasing frequency of all childbirth operations taken together+. The period 1871 to 1879 shows an average of 4.38 operations to every 100 births, the period 1900 to 1907 up to 8.12 operations to every 100 births." [Sidenote: C 48-2] "Figure 2 shows the +frequency of each class of operation in every 1,000 births+. Each class of operation shows an increase in number, but the increase has not been uniform throughout the various classes." [Sidenote: C 48-3] "Figure 3, A and B, shows the +share of each class of operation in the total number for the various periods+. A more leading part is taken by aftermath operations, by artificially induced premature birth, by perforation of the head and by Caesarean section on the living. Aftermath operations depend (like the use of the forceps) to such a degree on the teachings of the various schools for midwifery (and on the time at the doctor's disposal) that they can hardly serve as a standard of birth capacity. The Caesarean section, too, can hardly be taken as a guide, as a much wider view is taken now of the indications for this operation. But the equally increasing numbers of perforations of the head and artificially induced premature birth are well worthy of attention. For these two operations exclude one another. With the existing tendency to avoid perforation of the head by artificially inducing premature birth, a rise in the curve of premature births should correspond with a sinking of the perforation curve. 1871 to 1879 a maximum of the former actually coincides with a minimum of the latter; but from there on both curves rise, though not in the same degree. Premature births have become since then (see Fig. 2) more than eight times as frequent; perforations of the head have trebled; and dismemberments of the child have doubled. This fact must be considered as a sign of lessened birth capacity." [Sidenote: C 48-4] "Figure 4 shows the +decrease of the total number of stillbirths+." [Sidenote: C 48-5] "Figure 5 gives the +share which abnormal position of the child has in this total+, and a comparison of the two shows that whilst the total has decreased by 1.42% the decrease (1880 to 1889) has been 2.35% in the case of stillbirth through abnormal position. The conclusion is, that there is now more opportunity for hereditary transmission of the tendency to faulty position of the child than three to four decades ago." [Sidenote: C 48-6] "But Figure 6 proves that up to now an +increased inheritance of this tendency has not taken place+. The curves of these positions not only show irregularities but (with the exception of cross births) a tendency to sink."
