which have been most effective for man's advancement must have been 

 of slow growth, and of still slower diffusion among the nations. They 

 are to be regarded as the great remaining landmarks of man's progress, 

 whilst the mass of minor influences which contributed to their adoption 

 have fallen out of knowledge. 



The customs and institutions relating to the family state, and in the 

 probable order of their orgination, may be stated as the following : —
