 resulted, and reason had conquered instinctive habit. She

IV. The Last Stages in Man's Development 



The following passage, which I have translated from 

 Prof. Ernst Haeckel's standard work on the development of 

 Man,* has particular reference to those last stages in Man's 

 history, those stages to which the characters of babies that 

 have been considered above especially point, and from 

 which they have been derived. 



"As the twenty-second stage f in our human genealogical 

 tree we can place, next to the Half-Monkeys [Prosimians, 

 or Lemurs] the oldest and lowest Platyrrhines of South 

 America, with jaws of 36 teeth. They have developed 

 from the former by the perfection of the characteristic 

 monkey-head, by the particular modification of the brain, 

 of the jaw, of the nose, and the finger. From this Eocene 

 Monkey-stem, by modification of the nose and loss of four 

 teeth, have come the oldest Catarrhines or Old World 

 Monkeys, with jaws of 32 teeth as in Man. These oldest 

 stem-forms of the whole Catarrhinc group would, at any 

 rate, have been still very hairy, and furnished with long 

 tails : Tail-Monkeys {Menocerca). They certainly lived 

 during the oldest period of the Tertiary, and are found
