Figure 36. An X-ray photograph of the feet of the daughter to see 

 if she really did inherit the extra toes from her mother. In the left 

 foot the bones of the fifth and sixth toes are double, while in the 

 right foot this doubling extends only to the first two joints. 



Figure 37. An X-ray photograph of the feet of the mother 

 which shows that the doubling of the toes is not the same on 

 each foot. A comparison of these conditions reveals that the 

 daughter inherited the extra toe from her mother but that the 

 doubling in the right foot is like the mother's left; and the 

 doubling in the daughter's left is like the mother's right. Photo-
