CHAPTER VI. 



THE LAWS OF HEREDITY. 



WE will now very briefly consider the so-called laws 

 of heredity. These laws are not based on any very 

 scientific foundation, but they are nevertheless most 

 useful when we leave the broad theory and come down 

 to the very interesting study of individual facts. 



The following live "laws" are generally given as 

 including all the phenomena of descent. 



I. Direct Heredity. 

 II. Eeversional Heredity or Atavism. 



III. Collateral or Indirect Heredity. 



IV. Initial Heredity. 



V. Heredity of Influence. 



This is not Kibot's, or the usual classification. He 

 omits initial heredity altogether, although it is of 

 the utmost importance, and has perhaps a greater 

 influence upon the child than any other form of 

 heredity excepting only the direct, of which it is 

 really a form. 



Let us now glance at each of these rules or laws, and 

 see what part of the great law of heredity each includes.
