stages of development analogous with those of 

 embryonic life in other animals ; but reaches a more 

 advanced condition. 



From infancy to maturity, it is different. The 

 unfolding of life discovers a new and distinctive order 

 of functions, from which we infer a new order of 

 powers, of which no account appears in embryology, 

 or even in the physiology of the mature life. The 

 first stage of development in infancy is entirely 

 physical, quite explicable physiologically, and capable 

 of being expressed in terms applicable to material 

 existence. The only thing to be remarked is, that the 

 child is much slower in the exercise of the functions 

 of the special senses. In sight and movement, a 

 chick is at first vastly quicker than a child. The 

 reverse appears later. As development progresses, 

 the barn-door fowl increases in size, gains in muscle 

 and strength, but does not exercise sight functions 

 more than at first. For the fowl, food, corn-pickles, 

 flies, and objects around may stand for the maximum 

 visibile. For the child, as for the chick, birth is the 

 beginning of new conditions of nutriment, along with 

 which there is scope for freer muscular activity. 

 Beyond this, the difference is remarkable. The 

 similarity observed in the embryonic life continues 

 in the unfolding physical life. But a_later stage of 

 development in the life of the child introduces pheno&quot; 

 mena altogether singular. These belong to the visible 

 dawn of intelligence. This comes considerably after 

 the date of birth, when analogies of animal life are 

 being left behind. A higher life, with new functions, 

 begins to show itself. From this point, a new develop 

 ment proceeds under new conditions. Thought, not
