Fig. 134 gives the pedigree of the family Mampel from Kirchheim near Heidelberg (Lossen, 1905), and Fig. 135 is the pedigree of a family that settled in Carroll Co., Maryland, and has since spread over the country. It is remarkable because it contains records of female bleeders, whose occurrence has been doubted by Bulloch (1911).

Fig. 134. —Pedigree of hemophilia in the Mampel family, originally of Kirchheim near Heidelberg, Germany. Black symbols indicate bleeders; it is seen that they are males only, but they, in turn, have no bleeding sons.

Heavy ringed circles are normal females who transmit the trait. Lossen, 1905. The details of Lossen's paper are translated in the "Treasury of Human Inheritance," Parts V and VI, pp. 267–271.

Note. On account of the length of the chart it has been cut in two in the middle and the right-hand portion has been placed on the page, below the left-hand portion.
