124 MARRIAGE AND HEREDITY 



character, while the daughters had the temperament 

 of their father. It is certain that even when outward 

 resemblance is absent, and when there is no possi- 

 bility of imitation, children will take after one or other 

 of their parents in peculiarities of thought and feeling, 

 and proneness to certain constitutional disorders. 



The mule, the offspring of the he-ass and the 

 mare, is essentially a modified ass in appearance, 

 while the hinny, the offspring of the stallion and 

 the she-ass, is essentially a modified horse. A 

 monster engendered by a bull and a mare being 

 dissected at the Ecole V^t^rinaire of Lyons, some 

 curious physiological facts were disclosed. The case 

 is quoted by Lucas. The animal had the muzzle and 

 the eye of the bull, the teeth and stomach of the 

 horse — it did not chew the cud — the tongue and 

 spleen of the bull, and the womb and viscera of the 

 horse. From this strange example it is clear that 

 physical structure may be derived in pretty equal 

 measure from both parents. The fact is, moreover, 

 attested by anatomists both with regard to animals 

 and human beings. Lucas observes that a father 

 may transmit to a child the brain and the mothei 

 the stomach, one the heart, the other the liver, one 

 the kidneys, the other the bladder, and so on.
