The Families of A and B. Pedigree Chart I. 



BY GEO. p. MUDGE. 



I am indebted to Miss Gertrude Flumerfelt, who 

 was recently one of my students at the London School 

 of Medicine for Women, for the facts of this pedigree. 

 I cannot sufficiently express my obligation to her 

 for the interest which she manifested in this case, and 

 for the trouble and care which she took in elucidating 

 the various facts. 



The Facts of the Pedigree. 



This pedigree was constructed in 1907, by enquiry 

 of some intimate friends of the B family, f Tliere are 

 two families concerned, and they have apparently 

 lived for many generations in an English village. 

 Both families are very respectable, and their msmbers 

 as a whole are moderately well off, while some 

 members have been wealthy farmers. 



As already indicated, two families are primarily 

 involved in the pedigree, namely, the A and B 

 families. There exists a tradition in the village in 



* The Editor will be glad to receiv e from medical men and others, 

 family pedigrees showing the transmission of disease, peculiarities, 

 abnormalities, or of marked abilities, but not necessarily for publica- 

 tion. See Prologue. 



fThe symbolic letters employed to indicate the two families 

 concerned do not in any way reveal their identity. The two first 

 letters of the alphabet have been chosen for the necessary purposes of 

 description.
