Fig. 132. — Pedigree of multiple telangiectasis. I, 1, is an English woman 

 who was subject to epistaxis (nosebleed) and had rod spots on her face; her 

 daughter, II, 2, 60 years old, has a number of bright red angiomata distributed 

 over face, ears, lips, tongue, mucous membrane of mouth, and imicr surface of 

 all 4 eyelids. During last 6 years has had recurrent attacks of epistaxis. 

 By her first husband she had a son and 8 grandchildren of whom 1 

 suffers from epistaxis. By her second husband she had 8 children of whom 

 III, 3, has had epistaxis since 8 years and 2 small "spider naevi" on left 

 cheek and has a child of 11 who suffers from epistaxis; III, 5, has nose- 

 bleed and 3 small spots on cheek; his son is normal as yet; III, 11, has epis- 

 taxis; III, 16, has slight attacks of epistaxis but no spots visible. Weber, 1907.

 hausted, when the "core" falls out and the wound heals. 

 Binding up the wound does no good. The only death known 

 to have occurred through bleeding is supposed to have been

 ceded and the conclusion would not be weakened were a 

 specific hemophilia germ some day demonstrated. The par- 

 ticular method of inheritance is well illustrated by Fig. 133 

 of the Sullivan County strain. The males alone are af-
