Contains a great mass of material f<.)r the inheritance of psychical characters. The 
statistical ti'eatment is very defective. It is now being reduced by biometiic methods, but 
the value of the observations has yet to be settled.

Finds a correlation of '764 between the age of husband and wife at marriage. " If this 
be compared with that of stature ('280), span ('199), forearm ('198) or longevity ('223), it 
will make it possible to appreciate more clearly the precise extent of the unconscious 
assortative mating." Data from 2500 man-iage records in Chicago license office records.
